Explain the cardiac conduction cycle as shown on an EKG. 1. What is pericarditis? 2. What is pleurisy? 3. What is peritonitis? Which event causes the QRS wave on an ECG tracing? a. atrial depolarization b. atrial repolarization c. ventricular depolarization d. ventricular repolarization What ...
a. What is an EKG? b. How to interpret an EKG? During which phase of the cardiac cycle are the atrioventricular (tricuspid and mitral) valves open? a. Ventricular filling b. Isovolumetric contraction c. Ventricular ejection d. Isovolumetric relaxation ...
A single round of the cardiac cycle shows up in 3 main “waves” on an ECG—the P wave, the QRS complex, and the T wave. These waves reflect the activities of the heart’s electrical conduction system, which is composed of specialized muscle fibers. P wave A heartbeat starts with the...
