An ECG can detect abnormalities in your heart's rhythm and certain patterns that suggest portions of the heart may not be getting enough blood flow. The ECG may also show whether you are having a heart attack or find evidence of a previous heart attack. However ECGs are not perfect tests.
An electrocardiogram (EKG) measures your heartâs electrical activity. This noninvasive test can measure many things, from how fast the heart beats, to how well the heartâs chambers are conducting electrical energy. An abnormal EKG can mean many things. Sometimes EKG abnormalities are a normal variation of a heartâs rhythm, which does not affect your health. Other times, an abnormal EKG can signal a medical emergency, such as a myocardial infarction (heart attack) or a dangerous arrhythmia.
