Pj. Roach et al., ASYSTOLE AND BRADYCARDIA DURING DIPYRIDAMOLE STRESS-TESTING IN PATIENTS RECEIVING BETA-BLOCKERS, International journal of cardiology, 42(1), 1993, pp. 92-94
Only rarely have serious side effects been reported with the use of in
travenous dipyridamole. We describe two cases of severe bradycardia, o
f which one led to asystole, in patients undergoing dipyridamole-thall
ium studies. The association between beta blocker therapy and the seve
n reported cases of asystole with dipyridamole is discussed and mechan
isms postulated. Some caution is advised when patients on beta blocker
s or similar medications have dipyridamole-thallium studies.
