Could it be

supraventricular tachycardia (SVT)?

If you think you have SVT, it’s important that you learn all you can about it.

Suspect SVT?

Some people experience the symptoms of SVT without knowing they have it. These symptoms can often be dismissed, which only delays an accurate diagnosis.

Don’t be discouraged if you feel like this has happened to you. It’s okay to speak up and advocate for yourself by getting multiple opinions.

Common SVT misdiagnoses

  • Panic attack or anxiety
  • Atrial fibrillation
  • Atrial flutter

Getting an SVT diagnosis can take up to


SVT can be hard to diagnose. That’s because a doctor needs to observe your heartbeat during an episode. Since SVT starts and stops without warning, it can be difficult to catch it while it’s happening.

Diagnostic devices


In a healthcare setting

During an episode, healthcare providers can record your heart’s rhythm with an electrocardiogram (EKG, sometimes called ECG).

Between episodes

Cardiac monitoring systems can record your heart’s rhythm outside the healthcare setting. Examples include a Holter monitor, an event monitor, or an implantable loop recorder, which is a tiny monitor inserted under the skin.

Wearable devices

Wearable devices could alert you to SVT by keeping track of your heart rate. New pocket-sized models come with simple EKG/ECG technology to measure your heart’s rhythm.

Your care team members may change over time depending on your individual needs. Cardiologists, electrophysiologists, primary care providers, and nurses are the partners to help you understand and manage the condition.

A cardiologist treats heart disorders and diseases. Your primary care provider may refer you to a cardiologist to confirm an SVT diagnosis or discuss SVT treatment options.

electrophysiologist icon


An electrophysiologist is an expert in diagnosing and treating issues with your heart’s electrical system. They can perform tests to determine the specific cause of your heart rhythm abnormality. They also perform cardiac ablations.

Primary Care Provider PCP

A primary care provider (PCP) is your healthcare provider in non-emergency situations. They treat common conditions and help connect you with specialists.

Nurses and support staff

Nurses and support staff provide additional care such as obtaining past medical and cardiac history and monitoring your EKG (sometimes called ECG). They also provide education on managing the condition and medications.


Hear from others living with SVT

“If someone in your family has SVT, you have to be aware of their fears, challenges of getting around, and understanding where to go to get help.”
