Cardiac rate and hyperkinetic rhythm disorders in healthy elderly subjects: evaluation by ambulatory electrocardiographic monitoring

Abstract

We performed 24-hour ambulatory electrocardiographic (Holter) examinations in 50 retired hospital workers (30 men, 20 women), aged 58-85 years (mean age +/- SD: 65.9 +/- 4.6 years), with a normal clinical history, physical examination and baseline ECG. There was a significant difference between daytime and nocturnal mean heart rates (79.2 +/- 8.4 vs. 65.3 +/- 7.8 beats per minute), and between maximal (122.4 +/- 15.6 vs. 99.9 +/- 13.7) and minimal (57.9 +/- 10.8 vs. 51.3 +/- 8.0) diurnal and nocturnal heart rates. 92% of the subjects were shown to have supraventricular extrasystoles (SVE) in the 24 h recording, with 16% having more than 100 SVE/h. 68% had ventricular extrasystoles (VE), but only 6% had more than 100 VE/h. SVE were mainly diurnal, and VE were equally distributed between day and night. No other rhythm disturbances were found in this group of healthy elderly individuals.

Attention Disorders

Attention is involved in all cognitive activities, and attention disorders are reported in patients with various neurological diseases. Here are the latest discoveries pertaining to attention disorders.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.
