Extrasystole (premature contraction) is untimely depolarization and contraction of the heart or its individual chambers, it is the most frequently recorded form of arrhythmias. Extrasystoles can be found in 60-70% of people. Basically they are functional (neurogenic), their appearance is provoked by stress, smoking, alcohol, strong tea and especially coffee. Extrasystoles of organic origin arise from damage to the myocardium (ischaemic heart disease, cardiosclerosis, dystrophy, inflammation). [1]
