Extrasystole is a premature contraction of the muscles of the heart. As a result of the phenomenon, the normal rhythm of the heartbeat is disrupted, which affects the functioning of the organ and causes certain problems in the patient in the future. The condition can develop in healthy people under the influence of various factors.
When diagnosed, an irregular heartbeat is the main symptom that indicates a disorder. The patient has changes in the strength of the blows and an unstable pulse. Extrasystoles usually follow a normal muscle contraction, after which a pause occurs. Then the heart returns to its rhythm and continues to beat normally.
Symptoms usually worsen over time and may disappear with exercise. If signs of illness worsen with exertion, the patient has a serious complication of the condition. Other nonspecific symptoms of extrasystole are fainting (frequent dizziness), chest pain, and fatigue. In medical practice, there are cases when patients had a chronic cough as one of the manifestations of the disease.
Diagnostics and treatment
Differential diagnosis of the disease begins with the collection of a detailed medical history of the patient. Before the examination, it is important to determine if there are structural heart defects that may be causing the muscle to contract incorrectly. Then an ECG is prescribed, according to the results of which it is possible to fix the fact of the presence of the disease. The use of Holter monitoring is desirable, since a conventional cardiogram does not always provide an accurate diagnosis.
Isolated extrasystole with benign characteristics does not need treatment, but requires a healthy lifestyle and adherence to the doctor's instructions. In the healthiest patients, the disease can be cured by adjusting the balance of magnesium, calcium and potassium in the body. The most effective treatment is based on getting rid of the factor that triggered the onset of the disease. Antiarrhythmics, beta blockers, calcium channel blockers, and magnesium and potassium supplements are commonly used. Radiofrequency catheter ablation is an alternative method when other techniques are not effective.
Most often, the disease has a positive prognosis and can be completely cured. There are studies that confirm that the occurrence of extrasystole can significantly increase the risk of myocardial infarction and cardiac death. However, getting rid of the underlying cause of the disease reduces this risk and enables the patient to live a long and healthy life.
