WebApr 1, 2005 · Coronary blood flow is mainly determined by local oxygen demand. The vascular endothelium is the final common pathway controlling vasomotor tone. When anaesthetising patients with coronary artery disease, maintain coronary perfusion pressure and avoid tachycardia.

The cardiac cycle is then further divided into three stages - atrial systole, ventricular systole, and ventricular diastole. Below is a diagram that shows the big picture of the cardiac cycle events.
