Poruchy srdecního rytmu u hypertrofických kardiomyopatií
[Disorders of heart rhythm in hypertrophic cardiomyopathy]

Vnitrni lekarstvi. 1989 Jul ; 35 (7) : 625-31.

In 64 patients with hypertrophic cardiomyopathy 24-hour Holter monitoring of the ECG was made in order to detect the incidence of individual disorders of the cardiac rhythm. The examination revealed a large number of potentially malignant ventricular arrhythmias (47% of the patients). Most frequently polytopic ventricular extrasystoles were involved (31.3%), attacks of ventricular tachycardia (20.3%), less frequently bigeminy was recorded (10.9%) and early extrasystoles type R on T (3.1%). As to other disorders of the cardiac rhythm, paroxysmal supraventricular tachycardia was frequent (34.4%), atrial fibrillation or flutter (9.4%) and more numerous supraventricular extrasystoles (7.8%). Sinoatrial (4.7%) and atrioventricular blocks (7.8%) were relatively rare. Examination of patients with hypertrophic cardiomyopathy is an essential prerequisite for the initiation of early and effective treatment which can exert a favourable effect on the subsequent fate of the patients.

The aim of the work was a more detailed characteristic of patients with hypertrophic cardiomyopathy who are threatened by an increased risk of serious disorders of the cardiac rhythm and thus probably also by sudden death. The authors analyzed a group of 64 patients subjected to 24-hour monitoring of the ECG by the Holter system. The patients were subjected to echocardiographic examination and the distribution of the myocardial hypertrophy was described in detail, incl. its extent in per cent of the affected myocardium, the mean thickness of the myocardium (arithmetic mean of the thickness of the left ventricular musculature and septum divided into 10 areas) and the maximum thickness of the heart muscle. The authors found a significantly higher incidence of serious ventricular arrhythmias in patients with an extensive area of the hypertrophy and a greater thickness of the hypertrophic myocardium. In subjects with a positive history of syncopes there was a high incidence of serious supraventricular and ventricular disorders as well as ventricular disorders of the cardiac rhythm. No relationship was found between the incidence of arrhythmias and the presence or size of obstruction. Patients with extensive hypertrophy (i.e. an extensive area of hypertrophy and thickness of the myocardium) and patients with a history of syncopes form thus as regards life-threatening arrhythmias a risk group which after diagnosis should be without delay examined by the Holter system and then treated by medicamentous therapy.
