what kinds of tissue make up the cardiac conduction system
Overview. The conducting system of the heart consists of cardiac muscle cells and conducting fibers (not nervous tissue) that are specialized for initiating impulses and conducting them rapidly through the heart (see the image below).They initiate the normal cardiac cycle and coordinate the contractions of cardiac chambers.or the heart to pump efficiently and the systemic and pulmonary circulations to operate in synchrony, the events in the cardiac cycle must be coordinated.
