It’s an EKG device that monitors your heart activity. Your doctor may want you to wear a Holter monitor for a couple of days. This is a test that measures your heart’s electrical activity. How Are AFib and SVT Diagnosed?īoth conditions are usually diagnosed via an electrocardiogram ( EKG). Serious SVT can cause you to pass out or go into cardiac arrest. Many people have a fast heartbeat that’s more than 100 beats per minute, even when they are at rest. If you have SVT, you are more likely to notice that your heart is racing.
