These check-ups often occur days or weeks prior to a planned, non-cardiac surgery and typically involve a physical exam. You also may get blood tests, x-rays, and an electrocardiogram (ECG) — a quick, painless test that records your heart's electrical activity.
"These evaluations are designed to assess your chances of experiencing a heart-related problem during the surgery," says Dr. Brendan Everett, director of the general cardiology inpatient service at Harvard-affiliated Brigham and Women's Hospital.
