The LVEDP was measured during expiration at end-diastole which was defined electrocardiographically by the onset of the next cycle’s QRS wave from left ventricular pressure tracing recorded with a 50 mm Hg scale. Electrocardiographic analysis

WebElectrical waves track a systole (a contraction) of the heart. The end-point of the P wave depolarization is the start-point of the atrial stage of systole. The ventricular stage of systole begins at the R peak of the QRS wave complex ; the T wave indicates the end of ventricular contraction, after which ventricular relaxation (ventricular ...
