1. Describe the anatomy of movement of the wave of cell depolarization throughout the heart
during a cardiac cycle.
(BIoengineering)
Solution
The cardiac cycle is the series of events comprising a complete contraction and relaxation of the
heart's four chambers. A cardiac cycle lasts about 0.22 seconds in a normal, healthy adult heart.
Contraction of the heart depends on a network of nodes and fibers that carry electrical impulses
through the heart. These impulses are called action potentials. The cardiac cycle can be
visualized with an electrocardiogram, or ECG. A ECG breaks down the events of the cardiac
cycle into three waves identified by the letters P, QRS and T. Each wave shown on an ECG
represents an action potential carried out by the specialized cells of the heart.
