Cardiac conduction system, illustration
Cardiac conduction system, illustration. The electrical activity generated by the sinoatrial node activates the atrial muscle through the atrial conduction pathway and generates the P wave of an ECG. (electrocardiogram). Next, the ventricular muscle is excited through the intraventricular conduction system to produce the QRS wave of an ECG., by CHONGQING TUMI TECHNOLOGY LTD/SCIENCE PHOTO LIBRARY
