SUMMARY
The study was designed to assess by 24-hour Holter
monitoring the prevalence of arrhythmias in a
group of patients with hypertrophic cardiomyopa-
thy (HCM), defined by an echocardiographic de-
monstration of inordinate interventricular septal
thickening (>1.3 cm), their relatives and a normal
group. Fifty nine close relatives of eight patients
(out of a total of 11 patients who came to autopsy
with HCM in 1966-77) were studied. Twenty five of
them had HCM. Twenty normal subjects served as a
control group. Seven patients had >50 supraventri-
cular premature beats per day, but only one subject
in the group of relatives and the control group.
Eight patients with HCM had supraventricular
tachyarrhythmias. Thhree patients with HCM had
runs of ventricular tachycardia but none in the two
other groups. Two patients with HCM had coupled
ventricular ectopic beats, one in the control group.
Twelve patients with HCM had more than 10
ventricular ectopics per day as compared with four
in the control group and two in the group of
relatives. Subjects with unexplained interventricular
septal thickening should be investigated by Holter
ambulatory monitoring.
