Moderate altitude exposure warrants arrhythmia vigilance in elderly men; leaves open whether this translates to clinical events.
Does moderate altitude exposure increase the incidence of supraventricular and ventricular extrasystoles in healthy elderly men?
Moderate altitude exposure in healthy elderly men is associated with a twofold increase in supraventricular and ventricular extrasystoles and a shift in their circadian periodicity, likely due to beta-adrenergic activation.
