Abstract
5 normal young [male][male] were studied. Exercise lowered the T waves, with return toward normal in less than a min. During recovery the amplitude of T may become greater than normal. Adrenaline decreases the T waves for from 15-30 mins. Ergot-amine tartrate augments the T waves for as long as an hr. Atropine depresses the T waves. The effect is maximal in 1 hr. but may last 90 mins. Mecholyl decreases the T waves and causes tachycardia without preliminary brady-cardia. Right carotid sinus pressure causes an elevation of the T waves. The presence of such changes must be considered in interpreting electrocardiograms.This publication has 7 references indexed in Scilit:
