Frequently Asked Questions

Does the heart generate its own electrical impulses?

The heart generates its own electrical signal (also called an electrical impulse), which can be recorded by placing electrodes on the chest. This is called an electrocardiogram (ECG, or EKG). The cardiac electrical signal controls the heartbeat in two ways.

What starts the electrical activity of the heart?

In the normal heart, electrical activity is initiated by the Sinoatrial node (SAN) also referred to as the natural “pacemaker” of the heart. The SAN generates Action Potentials (AP’s) about 60-100 times a minute.

What is the normal electrical pathway of the heart?

Normal electrical pathway. The electrical current from the sinoatrial node flows first through the right atrium and then through the left atrium, causing the muscles of these chambers to contract and blood to be pumped from the atria into the lower heart chambers (ventricles).

How do electrical impulses affect the heart?

How do electrical impulses affect the heart? The heart's "electrical system" powers the heartbeat. If the electrical impulses that travel through the heart are abnormal or disrupted, the heart's chambers do not fill and contract properly. They may pump blood before they are filled adequately.
