Complications in 1000 consecutive treadmill tests.

ABSTRACT

Complication in 1000 consecutive Tread Mill Tests (TMT) done at the Cardiology Centre of Command Hospital (SC) Pune are reported. The tests were done following Bruce Protocol and analysed based on Selzer's criteria. Complications were noted in 18 cases (1.8%) which included ventricular fibrillation, ventricular tachycardia, atrial fibrillation, malignant VPBs, conduction disturbances, asystole following hyperventilation (HV), complete SA block following HV, atrial flutter following HV, hypotension and severe angina requiring ICCU care. No acute myocardial infarctions or deaths were noted. Coronary arteriography (CART) was done in 50 (5.0%) selected cases including 10 with complications. It is concluded that TMT is a safe procedure if carried out after proper patient selection and under supervision of an experienced and efficient team.
