How is a steady heart rate maintained?
How does the heart’s electrical system regulate your heart rate? The cells of the SA node at the top of the heart are known as the pacemaker of the heart because the rate at which these cells send out electrical signals determines the rate at which the entire heart beats (heart rate).

How does heart rate maintain homeostasis?
In order for a body to work optimally, it must operate in an environment of stability called homeostasis. When the body experiences stress—for example, from exercise or extreme temperatures—it can maintain a stable blood pressure and constant body temperature in part by dialing the heart rate up or down.
How do I reset my heart rhythm?
Cardioversion is a medical procedure that restores a normal heart rhythm in people with certain types of abnormal heartbeats (arrhythmias). Cardioversion is usually done by sending electric shocks to your heart through electrodes placed on your chest.
