About this document
Understanding the Wiggers Diagram by Kuro Shiro is a document available to read on EtoBox.
The document summarizes the cardiac cycle in 3 sentences: The cardiac cycle begins with the heart at rest and the left atrium filling the left ventricle, followed by ventricular contraction which increases ventricular pressure and ejects blood out of the heart. During ventricular relaxation, the mitral and tricuspid valves close and the ventricles fill passively from the atria. This cycle then repeats with atrial contraction pushing more blood into the ventricles.
