Question

Quizplus · Accepted Answer

The QRS complex indicates the depolarization of the ventricles during the cardiac cycle.

Answer: C
 The cardiac cycle refers to the sequence of events that occur during one heartbeat, including both systole and diastole.

Answer: D
 Stroke volume is the amount of blood ejected by the ventricles during each heartbeat.

Answer: F
 The sinoatrial node initiates the electrical impulses that regulate the heartbeat.

Answer: G
 Purkinje fibers are specialized cardiac muscle fibers that distribute the electrical stimulation to the ventricles, causing them to contract.

Answer: H
 The P wave represents the depolarization of the atria during the cardiac cycle.

Answer: A
 Systole refers to the phase of the cardiac cycle during which the ventricles contract, ejecting blood into the arteries.

Answer: E
 Cardiac output is the amount of blood pumped by the heart per unit of time, typically measured in liters per minute.

Answer: J
 The T wave represents the repolarization of the ventricles during the cardiac cycle.

Answer: B
 Diastole refers to the phase of the cardiac cycle during which the ventricles relax and fill with blood.
