The first step in the diagnosis of VT or VF is a medical history and physical examination by your electrical heart doctor (called an electrophysiologist). Many times, the first diagnose of a VT or VF is when a patient requires emergency assistance from 911. An electrocardiogram (EKG/ECG) obtained at the time of the heart rhythm problem will confirm the diagnosis of VT or VF. Based on your symptoms, your electrophysiologist may also recommend other tests such as:
Holter monitor – A portable, battery-operated EKG/ECG that is worn for a day or two and provides your physician with continuous data about the electrical activity of your heart.
Exercise stress test – A test performed on a treadmill or stationary bicycle to measure heart, lung and muscle function during physical activity. You are attached to an electrocardiogram (EKG/ECG) to record electrical activity of the heart.
Electrophysiology (EP) study – An invasive test where the doctor inserts pacing wires through a blood vessel into the heart to evaluate the electrical system of the heart.
Echocardiogram (also called echo) – This test uses sound waves to assess the function and structure of the heart muscle and valves.
