Hi, I have inappropriate sinus tachycardia, mitral valve prolapse, and PVC's. I just had an EKG today for chest pain, and the cardiologist told me it was fine. Then I saw the print out if results and it says "short PR interval, otherwise normal". I'm concerned about this, as I know it's associated with WPW. Also, I'm 9 months pregnant and worried about all of this during delivery. If anyone has any insight I would much appreciate it!
