To diagnose an arrhythmia, the doctor asks about eating and physical activity habits, family history, signs and symptoms and other risk factors for arrhythmia.

2.) Physical Examination

During physical examination few points are checked by the doctor:

· Checking for swelling in your legs or feet, which could be a sign of an enlarged heart or heart failure

· Checking s your pulse to find out how fast your heart is beating

· Listen to the rate and rhythm of your heartbeat

· Listen to your heart for a heart murmur

· Look for signs of other diseases, such as thyroid disease, that could be causing the arrhythmia

3.) Diagnostics Tests

· Blood Tests: to check the level of certain substances in the blood, such as potassium and thyroid hormone, that can increase your risk of arrhythmia.

· CT Coronary Angiography: to know the blockages

· Echocardiography(echo): This tells about the size and shape of your heart and how well it is working.

· Chest X-Ray: to know your heart is larger than normal.

· Electrocardiogram (ECG): This tells how fast the heart is beating.

·Holter monitor: This portable ECG device can be worn for a day or more to record your heart’s activity as you go about your routine.

·Implantable loop recorder:  to detect abnormal heart rhythms

·Ultrasound: to diagnose a suspected fetal arrhythmia in the womb.

·Stress test: Some arrhythmias are triggered or worsened by exercise. During a stress test, you’ll be asked to exercise on a treadmill or stationary bicycle while your heart activity is monitored. If doctors are evaluating you to determine if coronary artery disease may be causing the arrhythmia, and you have difficulty exercising, then your doctor may use a drug to stimulate your heart in a way that’s similar to exercise.

·Tilt table test: The doctor may recommend this test if you’ve had fainting spells. Your heart rate, EKG reading, and blood pressure are monitored as you lie flat on a table. You lie on a table that moves from a lying-down position to an upright position. The change in position may cause you to faint.
