Paroxysmal SupraVentricular Tachycardia (PSVT)

Submitted by Dr T on October 11, 2012 – 8:49am

I’m 46 years old. I have PSVT for more than twenty years. Most of the time, it has triggered at mid-night due to gastric congestion, usually if I have a drink or two, and late meal. Can gastritis trigger palpitations / PSVT.My last two occurences have been in the gap of five months. Before that it was 14 years gap. Shall I go for RFA as advised by the doctor?

Hi Gajendra,
I cannot advice on your treatment – I don’t have enough information.
However, if you were diagnosed with PSVT  20 years ago and thus far have not had any complications, there is no need to change treatment at this point unless something has changed. Here is some information about PSVT:
PSVT begins and ends suddenly. There are two main types:

  1. Accessory pathway tachycardias. A rapid heart rate due to an extra abnormal pathway or connection between the atria and the ventricles. The impulses travel through the extra pathways as well as through the usual route. This allows the impulses to travel around the heart very quickly, causing the heart to beat unusually fast.
  2. AV nodal reentrant tachycardia. A rapid heart rate due to more than one pathway through the AV node. It can cause heart palpitations, fainting, or heart failure. In many cases, it can be terminated using a simple maneuvers, such as breathing in and bearing down, and others performed by a trained medical professional. Some drugs can also stop this heart rhythm.

In your case, PSVT may need to be investigated if there are new symptoms, at which point a Holter monitor test, and (stress) ECHO and a EP study might be needed. Ablation is dependent on the findings at the time.
Hope this helps,
Dr T
