- Arrhythmia is a disturbance of the rate, regularity or sequence of heart contractions, not a single ailment.
- Missed beats, pauses and a rapid pulse require a visit to a cardiologist, or, if unavailable, to a general physician.
- Fainting, chest pain and sudden weakness with cold sweat require an immediate call for an ambulance.
- Examination includes electrocardiography, 24-hour rhythm monitoring, echocardiography, blood tests and stress tests.
- A diary of attacks with the time and circumstances of the missed beats helps the doctor understand what is happening more quickly.
What is arrhythmia
Arrhythmia is a condition in which the heart contracts differently from normal: too fast, too slow, or with interruptions. Below we look at what exactly happens in the body, which circumstances trigger a rhythm disturbance, and who experiences it more often.
What happens in the body
The heart works thanks to weak electrical signals that are generated in a special area of muscle tissue and then spread through the atria and ventricles. These signals set the sequence of contractions: first the chambers fill, then they push blood into the vessels. When the path of the signal changes or an extra focus of excitation appears, the order of contractions is disrupted. The heart may beat faster than usual, slower than usual, or skip individual beats. Because of this, blood moves through the vessels unevenly, and the organs receive either more or less blood. A person notices this as interruptions, a pause, thuds in the chest, or shortness of breath during usual exertion. The rhythm does not always restore itself, so it is worth having it assessed by a doctor rather than waiting for everything to pass.
What causes it to develop
- Coronary heart disease and a previous heart attack: areas of the muscle receive little blood and conduct the signal worse, so the rhythm is disrupted.
- Hypertension and heart defects: the walls and valves change under load, the chambers stretch, and the path of the electrical signal is distorted.
- Thyroid disorders: its hormones speed up metabolism, and the heart begins to contract more often than it should.
- Electrolyte disturbances: a lack or excess of salts in the blood prevents muscle cells from receiving and transmitting the signal on time.
- Stress and lack of sleep: constant tension and lack of sleep keep the nervous system excited and disrupt the natural rhythm.
- Excess caffeine, alcohol, or smoking: these substances directly affect the heart muscle, so they should be discussed with a doctor.
Who experiences this more often
Older people who already have heart or vascular disease encounter rhythm disturbances more often. Over the years, changes accumulate in the muscle, the conduction system works less smoothly, and disruptions occur more easily. Heredity also plays a role: if close relatives had arrhythmia, it is worth telling the doctor about it. In young people, the rhythm is more often disrupted against a background of severe stress, lack of sleep, intense training, or consumption of stimulating drinks. A separate group is those who have undergone heart surgery or have lived with high blood pressure for a long time. Noticing the problem is helped by your own observation: if the interruptions recur rather than happening once, this is a reason for examination. Age and heredity cannot be changed, but lifestyle and control of chronic conditions largely determine how often the rhythm will be troublesome.
What symptoms can there be?
Arrhythmia is noticed by the sensation of missed beats, a pause or a rapid heartbeat, but sometimes a rhythm disorder goes unnoticed. This section helps to work out which signs require attention and when help is needed immediately.
How it is noticed at the very beginning
Arrhythmia often begins with a feeling that the heart has paused for a moment or missed a beat, and such episodes are easily put down to tiredness after the working week. A person feels a sudden rapid heartbeat while sitting quietly or lying down before sleep, and explains it by stress or strong coffee. Weakness is added to these sensations, making the usual walk or climb up the stairs harder than usual. Dizziness and breathlessness on exertion are also often put down to lack of sleep, stuffiness in the room or general overfatigue. Meanwhile, the missed beats recur more and more often, and the intervals between them become shorter, and the person begins to listen to themselves. Some people do not feel rhythm disturbances at all, and then they are detected by chance at a doctor's appointment or during an examination. If such sensations recur, it is reasonable not to wait for them to pass on their own, but to book an appointment with a doctor and tell them when and under what circumstances they occur.
The signs that occur most often
- Missed beats or a pause in the heart: a person feels as if the heart has stopped for a moment or missed a beat, and this is the most common reason for seeking help.
- Rapid heartbeat: the rhythm speeds up without an obvious reason, at rest or with slight exertion, and this is noticeable without measuring the pulse.
- Weakness and dizziness: there is a feeling that there is not enough strength, and vision darkens, which interferes with working and leaving the house.
- Breathlessness on exertion: the usual walk or climb up the stairs is harder than before, and breathing becomes uneven faster than usual.
- Pain or discomfort in the chest: unpleasant sensations in the heart area accompany the episode and require a doctor's attention, not waiting.
- Fainting and pre-fainting states: loss of consciousness or a feeling of near-fainting suggests that a visit to the doctor should not be postponed.
When to seek help urgently
Examinations and tests
Examination for arrhythmia is built from simple to complex: first the doctor talks and examines, then prescribes instrumental and laboratory tests. Below is what exactly is used and what task each one solves.
How the examination begins
Examination for arrhythmia begins with questioning and examination, not with hardware procedures. The doctor finds out how the person feels the interruptions, under what circumstances they appear and how long they last. Then he measures the pulse, listens to the heart and assesses whether there are signs of heart failure. It is important to record the rhythm disturbance itself, and at the time of the appointment it has often already passed. Therefore, one examination alone is almost always insufficient to establish an accurate picture. Next, the doctor prescribes instrumental and laboratory tests to catch the episode and find its cause. Sometimes this requires long-term monitoring rather than a short recording in the office. Keep your own records of the attacks: they help the doctor choose the right examination.
What is prescribed and what it shows
What is worth preparing for the appointment
- Attack diary: records of the time, duration and sensations during the interruptions help the doctor understand their pattern.
- Previous tracings and reports: earlier heart recordings make it possible to compare the picture and not repeat what has already been done.
- List of medications taken: a list of everything the person takes regularly is needed to take into account the effect on the rhythm.
- Discharge summaries about other conditions: information about past illnesses and operations explains the possible causes of the disturbances.
- Test results: recent data on metabolism and hormones save time on repeat tests.
- Questions for the doctor: points written down in advance help not to forget anything and get clear answers at the appointment.
Which doctor should I see?
The choice of doctor for arrhythmia depends on how pronounced the rhythm disturbances are and whether the person has other heart conditions. Below — who to see, what happens at the first appointment and what areas of care make up the treatment.
Which specialist manages this condition
Arrhythmia is managed by a cardiologist, and if there is no cardiologist nearby, the initial appointment is conducted by a therapist. The therapist listens to the complaints, measures the pulse and blood pressure, assesses the general condition and, if necessary, refers to a cardiologist. The cardiologist clarifies the type of rhythm disturbance, compares it with the complaints and examination findings, and determines further tactics. If the arrhythmia is related to another condition, the cardiologist decides whether a specialist in that condition needs to be involved. At the first appointment, the doctor takes a history: when the palpitations appeared, how often they are felt, what triggers them. Then they prescribe examinations to see the rhythm over time, not only at the moment of the visit. If there is no specialist nearby, start with a therapist — they will assess the condition and advise where to go next.
What the treatment consists of
- Monitoring and rhythm control: regular checks of the heart's function allow the doctor to see changes and adjust tactics in time, rather than acting blindly.
- Selection of therapy by the doctor: the decision on rhythm support is made only by a specialist, based on the type of arrhythmia, its cause and the person's condition.
- Lifestyle changes: sleep, exercise, giving up stimulants and daily routine affect the rhythm, so these steps are discussed with the doctor as part of the care.
- Treatment of the underlying condition: if the arrhythmia is caused by another condition, addressing its cause often changes the nature of the rhythm disturbances as well.
- Surgery when indicated: surgical intervention is considered when other approaches do not give the needed result and there are direct grounds for it.
What depends on the patient themselves
Regular follow-up is the part of the result that rests on the person themselves, not only on the doctor. If visits and rhythm checks take place as agreed, the specialist sees the picture over time and notices changes earlier. Missed appointments and postponed examinations lead to rhythm disturbances remaining unnoticed, and the care tactics not changing in time. Notes about how one feels — when the palpitations occurred, what preceded them — help the doctor more accurately compare the complaints with the examination findings. Following the agreements on daily routine and exercise affects the rhythm no less than the visit to the specialist itself. If something in how one feels changes, it is worth telling the doctor rather than waiting for the next scheduled appointment. An open conversation about what is troubling and what one is unable to do makes the care more precise. The most reliable support is a calm and consistent following of the doctor's recommendations without pauses and self-cancellations.
What helps prevent an exacerbation?
Arrhythmia prevention relies on controlling risk factors and treating underlying conditions. Regular check-ups help to notice changes in the heart's function in time.
What to change in your habits
Giving up smoking and limiting alcohol noticeably reduce the strain on the heart and blood vessels. Nicotine speeds up the rhythm and narrows the vessels, and alcohol itself often becomes a cause of palpitations. Moderate physical activity keeps the heart toned and improves circulation. Calm walks, swimming, and light gymnastics without sudden jerks or overexertion are suitable. A balanced diet with plenty of vegetables, fish, and wholegrain products helps to keep weight and blood pressure within normal limits. An excess of salt and fatty food, on the contrary, increases the strain on the heart and blood vessels. If palpitations, weakness, or breathlessness appear with your usual level of activity, it is worth discussing this with a doctor rather than putting it down to tiredness.
What to keep under control
- Blood pressure: it is measured regularly, because a persistent rise creates extra strain on the heart and triggers palpitations.
- Smoking and alcohol: it is better to give them up altogether, since both factors directly affect the rhythm and the condition of the vessels.
- Physical activity: it should be moderate and regular, without sudden overexertion, so that the heart gets feasible training.
- Diet and weight: a balanced diet helps to keep body weight and blood pressure in check, reducing the strain on the heart muscle.
- Heart and thyroid diseases: they are treated in good time, because an uncompensated condition often affects the rhythm.
- How you feel: any new palpitations, weakness, or breathlessness should be noted and discussed with a doctor at the next appointment.
How often to see a doctor
Regular check-ups are needed even when you feel well, because changes in the rhythm are not always felt straight away. The doctor assesses blood pressure, pulse, and general condition, and if necessary refers you for further examination. Between visits it is useful to keep a diary of how you feel and to note episodes of palpitations, weakness, or breathlessness. Such records help to see the dynamics and to notice a link with activity, sleep, or diet. If a person is being treated for heart or thyroid diseases, monitoring is especially important for timely adjustment. Missed visits often lead to an exacerbation being noticed later, when it has become more pronounced. Therefore it is worth agreeing with the doctor in advance on the timing of the next check-up and not putting it off when how you feel changes.
What is worth remembering
A conversation about arrhythmia comes down to a few conclusions that are worth keeping in mind. They concern how the reader should behave with this condition and what to rely on when making decisions.
Main conclusions
Arrhythmia is not a single ailment but a general name for various heart rhythm disorders, and the sensations they cause can differ greatly. Skipped beats, pauses or a rapid pulse do not always mean danger, but they are also no reason to ignore them. Arrhythmia often goes unnoticed, so how you feel is not the only guide for assessing your condition. Records of episodes, their timing and circumstances help the doctor understand what is happening more quickly. It is not worth putting off a visit if the episodes recur or interfere with everyday activities. The basis for a decision is not someone else's experience or advice from a chat, but a conversation with a specialist and the results of examinations. With arrhythmia, it is more sensible to find out the cause than to spend years blaming everything on fatigue or age.
