Smoking, drinking alcohol, or using illegal drugs

How is SVT diagnosed?
Your healthcare provider will ask about other health conditions and your symptoms. He will also listen to your heart and lungs. You may need any of the following tests:
Blood or urine tests are done to check for causes of SVT.
An EKG is a test to record your heart rhythm and how fast your heart beats. It is used to check for problems with your heart. Your healthcare provider may do an EKG when you are resting, then again after you exercise. You may also need to wear a portable heart monitor at home for a short time.
A chest x-ray shows a picture of your heart and lungs.
An echocardiogram is a type of ultrasound.
Sound waves are used to show the structure and function of your heart.A tilt table test checks your heart and blood pressure when your body changes positions.
An electrophysiology study is a procedure to map the electrical pathways in your heart that control your heartbeat.
How is SVT treated?
Treatment will depend on what is causing your SVT and your symptoms. You may not need treatment or you may need any of the following:
Medicines help control your heart rate and rhythm.
Vagal maneuvers are ways to use your own body to slow down your heart rate. Your healthcare provider may have bear down like you are having a bowel movement. You healthcare provider may teach you how to do vagal maneuvers so you can do them at home.
Carotid sinus massage is a type of massage to help slow your heart rate. Your healthcare provider will apply steady pressure to a blood vessel on one side of your neck. Do not do a carotid sinus massage on yourself or anyone else.
Cardioversion is a procedure to return your heart rate and rhythm to normal. It can be done with medicine or an electric shock. You may need cardioversion if medicine does not work.
Ablation is a procedure that uses a catheter to damage the small area of your heart that is causing abnormal electrical signals. This will stop the electrical problem and allow your heart to beat regularly.
