    Electrocardiogram

    An electrocardiogram (ECG or EKG) reveals how your heart’s electrical system is working. The ECG senses and records your heartbeats, or rhythms. The results are printed on a strip of paper. An ECG can also help your doctor diagnose whether:
    You have arrhythmias
    Your heart medication is effective
    Blocked coronary arteries (in the heart) are cutting off blood and oxygen to your heart muscle
    Your blocked coronary arteries have caused a heart attack
