Maximum treadmill exercise electrocardiography in female patients.
Exercise testing has become standardized for the diagnostic and functional evaluation of male patients but little data is available regarding its specificity and sensitivity in the female. Therefore, maximum treadmill exercise (Bruce protocol) was performed on 98 consecutive females and compared to coronary arteriography. Using 50% obstruction as indicating coronary artery disease and 1 mm ST-s...
متن کاملMaximal treadmill exercise electrocardiography. Correlations with coronary arteriography and cardiac hemodynamics.
SUMMARY Electrocardiograms were recorded during and at 2-min intervals following maximal treadmill exercise in 100 patients and were correlated with coronary arteriograms, left ventricular cineangiograms, and resting and exercise cardiac hemodynamics. The incidence and extent of exercise-induced "ischemic" S-T segment depression increased significantly (P < 0.01) with increasing extent of coron...
متن کامل[Heart rate recovery and treadmill exercise score as predictors of mortality in patients referred for exercise ECG].
CONTEXT Both attenuated heart rate recovery following exercise and the Duke treadmill exercise score have been demonstrated to be independent predictors of mortality, but their prognostic value relative to each other has not been studied. OBJECTIVE To assess the associations among abnormal heart rate recovery, treadmill exercise score, and death in patients referred specifically for exercise ...
متن کاملNormal electrocardiographic waveform characteristics during treadmill exercise testing.
Forty asymptomatic male patients at low risk for cardiovascular disease completed maximal treadmill testing. Electrocardiograms from leads CC5, CM5, V5, Yh and Z were recorded across multiple pretest, exercise and recovery conditions. ECG waveforms were subsequently digitized, averaged and processed to provide Q-, R-, S- and T-wave amplitudes, ST-segment means and slopes, and QS- and RT-interva...
متن کاملSudden Strenuous Exercise in Healthy Men
In ten healthy, asymptomatic men, intra-arterial pressure and electrocardiograms were recorded during various types of exercise. Potential subendocardial blood flow was estimated from a diastolic pressure time index (DPTI) and myocardial oxygen requirements estimated from the tension time index (TTI). The ratio DPTI/TTI provided an estimate of the supply/demand relationship. With sudden vigorou...
