“Events in cardiac cycle” Look at this. Understanding this graph is a key to understanding hemodynamics and how the heart works (and more importantly what happens when it fails). *I learn and remember by drawing/copying stuff, there are probably better graphs out there than mine.
Structure and actions: LOCATION:- The heart of humans is located in the chest cavity.The heart is enclosed in a double membranous sac-the pericardial cavity,which contains the pericardial fluid.Pericardium protects the heart,prevents it from over.
Systole is the contractile phase of the cardiac cycle and diastole is the relaxation phase of the cardiac cycle. Cardiac Cycle Ventricular filling: Mid-to-late ventricular diastole (includes atrial systole, P-Q interval) Ventricular systole: isovolumetric contraction and ejection phase (Q-T interval) Quiescent phase: isovolumetric relaxation in early ventricular diastole until atrial contraction (end of T wave … Continue reading The Cardiac Cycle for NCLEX
