Final answer:
The normal feline heart rate is 150 to 220 beats per minute, which differs from the human resting heart rate of 60-100 beats per minute. Bradycardia in humans occurs when the resting rate drops below 60 beats per minute.
Step-by-step explanation:
The normal feline heart rate ranges from 150 to 220 beats per minute. This is considerably faster than the human heart rate, which for an adult at resting is typically between 60-100 beats per minute. In cats, a heart rate below this range could be a sign of a health issue, just as bradycardia in humans represents a resting rate dropping below 60 beats per minute. The comparative rates of the conduction system in a human heart show the sinoatrial (SA) node firing at 80-100 impulses per minute, which is the natural pacemaker of the heart, while other parts of the conduction system like the atrioventricular (AV) node and Purkinje fibers have inherently slower firing rates.
