Stress-induced ventricular arrhythmias

Psychosom Med. 1979 May;41(3):259-62. doi: 10.1097/00006842-197905000-00008.


Restraint stress produced ventricular arrhythmias in seven of seven guinea pigs monitored by a Holter ECG recorder. Couplets and ventricular tachycardia, never seen in unrestrained guinea pigs, were noted in three. The arrhythmias were associated with high heart rates which showed no tendency to decrease during the restraint period.
