Evaluation of left ventricular relaxation using the continuous-wave Doppler velocity profile of aortic regurgitation: noninvasive measurement of left ventricular negative dP/dt and time constant.

abstract：:The usual normal S-T segment of the surface electrocardiogram (ECG) contributes little to the diagnostic procedure. When the S-T segment is too long or too short, or when it is displaced upward or downward, it is commonly abnormal. Under such circumstances, an S-T segment abnormality usually contributes considerable d...
