Cardiac arrhythmias in a healthy elderly population: detection by 24-hour ambulatory electrocardiography
Twenty-four hour ambulatory electrocardiographic examination was preformed in 98 healthy active subjects, ages 60 to 85 years, who were participants in a longitudinal study on aging. Normal health was confirmed by noninvasive testing, including maximal treadmill exercise (98/98) and thallium scintigraphy (38/98). Our studies indicated that a healthy population of elderly subjects shows a substantial prevalence of supraventricular ectopic beats and ventricular ectopic beats, both isolated and complex. High degree AV block, profound sinus bradycardia, abnormal sinus pauses and sinus arrest are rare in normal elderly subjects.

Bradyarrhythmias are slow heart rates. Symptoms may include syncope, dizziness, fatigure, shortness of breath, and chest pains. Find the latest research on bradyarrhythmias here.
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.
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.
