Mar 12, 2023 · The electrical system of the heart is critical to how it functions. It controls the electrical impulses that cause your heart to beat and their conduction, which organizes the beating of your heart. The movement of electrical signals across the heart is what is traced on an electrocardiogram (EKG). The EKG is also what allows irregularities in ...

The common symptoms of arrhythmia could include: 1. Heart palpitations. This is an unpleasant ability to feel your heartbeat. This includes feeling like your heart is pounding, racing or skipping beats. 2. Dizziness or lightheadedness. This can include fainting and passing out or having instances of nearly passing out. 3. Sudden loss of consciousne...
A diagnostic tool called an electrocardiogram can analyze your heart’s electrical activity. Abbreviated as ECG or EKG, this is a test that measures your heart’s electrical activity using sensors attached to your chest. There are several ways to perform an EKG. 1. Resting. While seated or lying down, several sensors are attached to the skin of your ...
There are several ways to treat problems with your heart’s electrical system. 1. Medication. Several medications can help your heart beat properly. Some of these do so directly by controlling the way your heart's cells function. Others can do this by treating related issues like your blood pressure or keeping your blood from clotting, making it eas...
The heart's pumping action is regulated by an electrical conduction system that coordinates the contraction of the various chambers of the heart. How does the heart beat? An electrical stimulus is generated by the sinus node (also called the sinoatrial node, or SA node).
Jun 6, 2023 · An electrical “wiring system” is responsible for causing the heart to beat. Each heartbeat is triggered by an impulse that starts in the sinus node , which is a group of cells in the wall of the right atrium.

The sinoatrial node (SA node): Known as the heart's "pacemaker", this node fires at regular intervals, causing the heart to beat. The atrioventricular node (AV node): the electrical "relay station" between the upper and lower heart chambers.
Your heart’s conduction system is the network of signals that keeps your heart beating. These electrical signals make your heart contract or relax. Each contraction also controls blood flow through your heart.
