I had catheter ablation last year for svt avnrt. now i am 9weeks pregnant and have irregular heartbeats again.my heart pauses for 10 sec before the next beat. i can't breath. is it svt? what do i do?

Revisit the issue: Please let the electrophysiologist performed the procedure know this without delays... In addition, keep your ob/gyn informed of this as well... Wishing you the best luck!

Arrhythmia : It doen't sound like svt, it may however be related to pregnancy and the ablation. See your doctors for evaluation.

See Doc: It is impossible to know for sure what your irregular heart beat without testing, which will likely include an ekg, or a home monitor (holter or event recorder) to determine what it is you have and if any treatment is needed.
