Comparison of QRS score and treadmill performance for assessing ventricular function after myocardial infarction. 1984

R Gupta, and S Gupta

QRS score as a means to assess left ventricular ejection fraction (LVEF) following acute myocardial infarction (AMI) has been developed recently and its significance confirmed by various studies. Similarly, the value of maximal treadmill exercise test as a means to assess functional capacity is well known. The present study was done to determine if there is any correlation between QRS score and treadmill exercise performance. Twenty patients with AMI, 3 months after the event, were studied. No significant correlation was observed in terms of duration of exercise (r = -0.007, p = 0.48) or magnitude of ST segment depression (r = 0.015, p = 0.475). QRS score denotes the resting LVEF while exercise-induced ischemia produces changes in dysfunctioning myocardium. These two tests denote different parameters and a judicious combination of both is suggested to assess patients following AMI.

D004562	Electrocardiography	Recording of the moment-to-moment electromotive forces of the HEART as projected onto various sites on the body's surface, delineated as a scalar function of time. The recording is monitored by a tracing on slow moving chart paper or by observing it on a cardioscope, which is a CATHODE RAY TUBE DISPLAY.	12-Lead ECG,12-Lead EKG,12-Lead Electrocardiography,Cardiography,ECG,EKG,Electrocardiogram,Electrocardiograph,12 Lead ECG,12 Lead EKG,12 Lead Electrocardiography,12-Lead ECGs,12-Lead EKGs,12-Lead Electrocardiographies,Cardiographies,ECG, 12-Lead,EKG, 12-Lead,Electrocardiograms,Electrocardiographies, 12-Lead,Electrocardiographs,Electrocardiography, 12-Lead
D005080	Exercise Test	Controlled physical activity which is performed in order to allow assessment of physiological functions, particularly cardiovascular and pulmonary, but also aerobic capacity. Maximal (most intense) exercise is usually required but submaximal exercise is also used.
