Symptoms most often start and stop suddenly. During an episode, they can last for a few minutes or several hours. Symptoms may include:
- Chest pain or tightness
- Rapid pulse
- Shortness of breath
- Dizziness and light headedness
Some patients complain of fatigue after episodes that can last days. Additionally patients report feelings of anxiety or uncertainty between episodes which can be quite limiting.19,20
Depending on the frequency of episodes, PSVT may be challenging to diagnose. Symptoms due to unrecognized PSVT are sometimes ascribed to psychiatric conditions such as panic attacks especially in women.7
The diagnosis of PSVT is based upon interpretation of the electrocardiogram (ECG or EKG) during a PSVT episode. However, due to the tansitory nature of PSVT, a diagnosis can be difficult to confirm because the episode may resolve before the patient presents for medical care. New technological developments with portable cardiac monitors are expected to facilitate the diagnosis of PSVT by allowing ECG measures to be taken in the outpatient setting when a PSVT episode arises.
I was finally diagnosed with paroxysmal supraventricular tachycardia (PSVT) after multiple emergency room (ER) visits where episodes would stop prior to examination. I went to an ER and they caught it on the EKG.
