To find out whether you have supraventricular tachycardia (SVT), your health care professional will ask you questions about your symptoms and do a physical exam. These questions might include:
During the physical exam, your health care professional will listen to your heart and lungs. He or she will also feel your thyroid gland on your neck. Other tests may include blood tests and an echocardiogram (an ultrasound that shows pictures of the heart in motion).
Your health care professional will do a test called an electrocardiogram (ECG). During an ECG, sticky patches (electrodes) are placed on your chest. Each electrode has a wire that goes to the ECG machine so it can record your heart's electrical activity over several minutes. If you are in SVT, the machine will be able to measure it.
If you do not have an episode of SVT during your health visit, you may be given an electrocardiogram that you can wear at home. You may be asked to wear:
If you're ECG shows SVT, your health care professional may want to perform an electrophysiology study to determine what type of SVT you have and what is causing it. This test is performed in the hospital. You will be sedated and wires are passed through your veins into your heart. Your doctor can look at different sections of your heart and see how they are sending electrical signals.
