What are some Reasons a physician may order an electrocardiogram?

A physician may order an electrocardiogram (ECG or EKG) to evaluate symptoms such as chest pain, palpitations, or shortness of breath, which may indicate heart problems. It can also be used to monitor heart health in patients with known conditions like arrhythmias, heart attacks, or to assess the effects of certain medications. Additionally, an ECG may be part of a routine examination for preoperative assessments or to screen for Heart disease in asymptomatic patients.
