AB  - 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.
