Ventricular ectopy frequency and complexity not altered by exercise training in coronary disease patients

L J LaslettE A Amsterdam


To assess the effect of exercise training on ventricular ectopy in coronary artery disease patients, 21 patients with coronary disease had 24-hour ambulatory electrocardiograph recordings done at entry into a cardiac rehabilitation program and after 6 months' exercise training. Mean frequency of premature ventricular contractions was not significantly changed, being 9.7 +/- 33.0/h before and 13.2 +/- 94.3/h after training. 9 demonstrated an increased, 9 a decreased, and 3 an unchanged frequency. Lown grade of ventricular ectopy was similarly not consistently changed with training.

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.
