Electrocardiogram (ECG or EKG) is used by doctors to check a
person’s heart rate and rhythm. This test helps doctors detect
a heart attack, heart disease, any abnormal heart rhythms, or
an enlarged heart that may result in heart failure.
It records the heart’s electrical activity through tiny electrode
patches attached to the skin of the person’s arms, legs, and chest.
ECG is a safe, quick, and painless testing technique
