To review:
Match the term bradycardia with the most closely related descriptions given below:
Vein to the left atrium
Covers outer surface of the heart
Supplies blood to heart muscle
Lines inner surface of fibrous pericardium
Slow heart rate
Functional syncytium
Muscular wall of the heart
Relaxation phase of the cardiac cycle
Vein to the right atrium
Contraction phase of the cardiac cycle
Introduction:
A continuous contraction as well as the relaxation of the heart chambers give rise to the heartbeat, which can be recorded as pulse rate. The normal pulse rate ranges in between 50-90 bpm (beats per minute). This range may vary depending on the physical condition of the body. The condition that results in an abnormal heartbeat is known as arrhythmia.
