Get a Baseline for Your Heart
If you're under 40 and feel fine, insist on having an electrocardiogram test during your next physical. This provides a healthy baseline that your doctor can use as a comparison when you're older. In fact, photocopy it down to wallet size. Emergency-room docs will be able to compare that normal EKG with the one taken in the ambulance to decide on the best treatment.
