Twenty-four-hour electrocardiograms were recorded in 50 subjects (44 women, 6 men) older than 80 years without cardiovascular disease and with normal standard electrocardiographic responses. During waking and sleeping periods, the mean sinus rates were, respectively, 78 +/- 3 and 64 +/- 1 beats/min; heart rate ranged from 43 to 180 beats/min over 24 hours. Supraventricular tachycardia (SVT) was present in 28% of the subjects. Nocturnal sinus arrhythmia was only noted in 12% of the patients; it was accompanied by sinus pauses of 1.8 to 2 seconds, and 1 woman had a transient pattern compatible with atrioventricular dissociation. Supraventricular ectopic contractions (SVECs) were present in all cases. The frequency was less than 1 per hour in 25% and more than 20 per hour in 65%. Serious supraventricular tachyarrhythmias included an episode of ectopic atrial tachycardia (1 subject), a short run of atrial fibrillation (1 subject) and of flutter (1 subject), and several episodes of supraventricular tachycardia (2 subjects), all accompanied by more than 50 SVECs per hour. The number of ventricular premature contractions (VPCs) exceeded 10 per hour in 32% and were multifocal in 18%. There were couplets in 8% and a run of 6 VPCs in 1 subject (2%). In conclusion, sinus pause and atrioventricular block are unusual in people older than 80 years without apparent heart disease. In contrast, frequent SVECs and VPCs are more common. This study stresses the difficulty of evaluating the normality of the electrocardiogram with portable monitoring in the older population.
