Heartbeat is the feeling of rapid and (or) amplified heart regardless of their actual frequency and force. True increase in heart rate is called tachycardia (see).
Palpitations may be frequent, regular, and even slow heart rhythm and may not appear at increased frequency of cardiac contractions. In healthy people the emergence of a heartbeat facilitate changes of excitability of nervous system, regulating the activity of the heart under the influence of great physical exercise (especially in untrained individuals), excitement, high temperature, of the abuse of tobacco, alcohol, strong tea and coffee. In pathology causes palpitations different: neurosis, damage to the nervous system, regulating the activity of heart, a change of metabolic processes in myocardium and so on
Palpitation occurs in patients with diseases of cardiovascular system (with endocarditis, myocarditis, heart diseases, hypertension, myocardial infarction, atherosclerotic cardiosclerosis and others), especially with the advent of heart failure. Often the heartbeat is noted for violations heart rhythm: sinus and paroxysmal tachycardia, atrial fibrillation, arrythmia (see heart Arrhythmia). The heart rate may occur with fever, severe anemia, hyperthyroidism, menopause; sometimes it appears in diseases of the abdominal cavity in the pathological reflexes at heart.
Treatment should be directed at eliminating the underlying disease. In addition, recommended sedatives: 2-3% solution of sodium bromide by 1 table l 3 times a day, camphor bromide 0.25 g 3 times a day, preparations of Valerian, and a cold compress on the area of the heart.
