What is an EKG Test?

An EKG, or electrocardiogram, is one of the most common and simplest medical tests used to evaluate heart health. The test works by recording the electrical signals that make your heart beat. These electrical impulses control the rhythm and rate of your heartbeat, and by measuring them, doctors can detect various heart problems.

How Does an EKG Work?

During an EKG, small adhesive patches called electrodes are placed on specific areas of your chest, arms, and legs. These electrodes detect the electrical signals produced by your heart and transmit them to a machine that converts these signals into a visual graph or printout. The entire process typically takes 5-10 minutes, and you can resume normal activities immediately afterward.

Why Do Doctors Order EKGs?

Doctors may order an EKG for various reasons, including evaluating chest pain or palpitations, screening before surgery, monitoring known heart conditions, checking for signs of a previous heart attack, or assessing the effects of medications on the heart. EKGs are often the first diagnostic tool used in emergency departments when patients report chest pain or cardiac symptoms.

What Can an EKG Detect?

An EKG can identify several cardiac conditions including arrhythmias (irregular heartbeats), acute or previous heart attacks, enlarged heart chambers, electrolyte imbalances, and problems with the heart's conduction system. The test can also show if you have inadequate blood flow to the heart muscle.

Understanding EKG Results

A normal EKG shows a consistent rhythm with regular intervals between heartbeats. Medical professionals analyze the size, shape, and direction of the waves on the EKG strip. Any deviations from normal patterns may indicate heart problems. Your doctor will explain any abnormal findings and recommend follow-up tests if necessary.
