An electrocardiogram (ECG or EKG) is a test that monitors the electrical activity of your heart. The ten-minute test involves a technician inserting twelve wires to your chest and then receiving a 12-line printout that shows your heart's activity during a 10-second timeframe.

So, what exactly can an EKG tell you about the health of your heart?
1. An EKG can detect arrhythmias (an abnormal heart rhythm).
A healthy heart should beat in a regular rhythm. When the electric signals transmitted from one portion of your heart to another malfunction, the heart beats irregularly, resulting in an arrhythmia. Because an EKG measures the electrical activity of your heart, it detects cardiac arrhythmias rapidly.
2. An EKG can tell whether or not your heart is getting enough oxygen.
Your heart is a powerful muscle that requires a lot of oxygen to stay strong and perform properly. However, ischemia, a perilous state in which the cardiac tissue is underperfused, can occur due to blockages or constrictions in the coronary blood vessels. If your heart suffers from prolonged ischemia, the muscle can begin to deteriorate, resulting in cardiac failure and possibly death. An EKG is a helpful instrument that allows medical doctors to assess how much oxygen your heart is receiving and to treat immediately if your heart is ischemic, preventing potentially fatal complications.
3. An EKG can identify whether or not your heart is enlarged.
A healthy heart is around the size of your fist and is placed in your chest slightly left of center. However, several medical problems can result in cardiomegaly (an abnormally enlarged heart.) Untreated high blood pressure, viral infections of the cardiac muscle, advanced age, and heart failure are all potential causes. Cardiomegaly is frequently detected on an EKG as excessively big waveforms, which can alert your doctor to a significant underlying problem.
4. An EKG can tell you if you've ever had a heart attack.
While heart attacks frequently create major symptoms that drive patients to seek emergency medical assistance, symptoms in 45 percent of cases are so minor that patients are unaware anything is wrong with their heart. These are referred to as "silent" heart attacks, which often manifest as characteristic abnormalities on an EKG weeks or months later, alerting your medical provider that you have a potentially dangerous blockage in your coronary arteries that has previously caused ischemia and will likely cause an even worse event in the future if left untreated.
If you have severe symptoms, such as chest discomfort, shortness of breath, dizziness, or pain in your arm or jaw, go to the nearest emergency room or call emergency response units.
