PSVT treatment (home remedies particularly) are as follows:

1. Exercise called Valsalva maneuver where you hold breath and strain as if you were trying to have bowel movement,
2. Coughing while sitting with your upper body bent forward.
3. Splashing ice water on your face.
4. You also need to avoid smoking, caffeine, alcohol, and illicit drugs.

PSVT is not a particularly life threatening disorder. Only if there are heart diseases present, it cause lead to congestive heart failure or angina. There are also many emergency and long term treatments to slow down a patient's heart externally, but those are done only for the patients with repeats episode of PSVT. If you want to consult with different doctors I can recommend some good hospitals.
