What is electrocardiogram?

An electrocardiogram is a simple test that can be employed to check the rhythm and electronics activity of your heart. Sensors connected to the skin detect the electrical signals generated by your heart every time it beats.

The electrical signals in the heart are recorded by an electrocardiogram. It's a prevalent and painless test for detecting heart problems and monitoring heart health.

An electrocardiogram, also known as an ECG, is frequently performed in a doctor's office, clinic, or hospital room.

It is a heart electrogram, which is a chart of voltage over time of the electrical activity of the heart recorded with electrodes placed on the skin.
