WebMar 27, 2024 · Furthermore, echocardiography pointed to the development of DCM-associated cardiac remodelling, namely decreases in LV posterior and septal wall thicknesses, LV end-systolic and end-diastolic diameters, as well as a decrease in heart rate (HR) and LV volumes during the cardiac cycle at 4, 8 and 12 weeks after STZ injection. WebThe cardiac events that occur from beginning of one heartbeat to the beginning of the next are called the cardiac cycle. The complete cycle involves both ventricular contraction and ventricular relaxation. Each cycle is initiated by spontaneous generation of an action potential in the SA node.
