Passive ventricular filling

Webpassive occurs when the tricuspid or mitral valve open due to greater pressure in the ventricle than the atrium and begins filling. active is when the atria contract draw the … WebRapid ventricular filling. 5. Slow ventricular filling (diastasis). 6. Atrial contraction. The duration of the cardiac cycle is inversely proportional to the heart rate. The cardiac cycle duration increases with a decrease in the heart rate and on the other hand it shortens with increasing heart rate. At a normal heart rate of 75 beats per
