title: [ECG changes in hypertrophic cardiomyopathy in children (data of routine and circadian ECG)].
abstract: Analysis is made of the routine and circadian ECG in 32 children with hypertrophic cardiomyopathy. The signs of myocardial hypertrophy of some or other parts of the heart were discovered in 29 children (90.6%). The signs of left ventricular hypertrophy were the most suggestive ones, whereas the signs of left atrial hypertrophy and right heart hypertrophy were observed less frequently. The use of the daily ECG monitoring allowed rhythm and conduction disorders to be revealed in 30 children (93.8%). It should be mentioned that in patients with the obstructive form of the disease, the signs of myocardial hypertrophy and heart arrhythmia on the ECG occurred much more often than in children suffering from the non-obstructive form. In accordance with the observations, prognostically unfavourable disorders of heart rhythm are not characteristic of children, they occur rarely, being primarily seen in the obstructive form of the disease. The daily ECG monitoring not infrequently allows the identification of heart arrhythmias and transitory disorders of conduction, which cannot be recorded on routine electrocardiography.
