Duration of ventricular diastole
WebVentricular diastole is the period during which the two ventricles are relaxing from the contortions/wringing of contraction, then dilating and filling; atrial diastole is the period during which the two atria likewise are relaxing under suction, dilating, and filling. Is diastole ventricular systole? WebObjective: The aim was to elucidate the alterations of left ventricular diastolic properties, taking into account changes in unstressed length during exercise stimuli with and without …
