How does the heart beat?

The heartbeat. The usual pattern of a heartbeat starts when an electrical impulse is produced by part of your heart called the sinus node. The impulse is conducted to the top chambers of your heart (the left atrium and right atrium). This causes them to contract, pushing your blood into two lower, larger chambers (the left and right ventricles). The electrical impulse is then transmitted to the ventricles causing them to contract. This pushes the blood out of your heart to your lungs and the rest of your body.


The chambers and electrical conducting system of the heart


Your heart will usually beat between 60 and 100 times a minute when you’re resting. There are certain times when it may beat faster or slower than this, for example if you’re exercising or depending on how fit you are.

Changes in rate brought about by variations in activity, diet, medication and age are normal and common. When a heart begins to race for no apparent reason, however, it can be a sign of an abnormality in the electrical pathway and is cause for evaluation. See PCP. Read more...
