ok so lats time i was taken to thr ER I went in with a hr of like 131bpm with pvc's they said it was sinus tach arrythmia with PVC's 3 hours later when they released me my pulse was in the 40's and they said they were releasing me with sinusbrady arrythmia w/ PVC's. I don't understand how you can have one and then a few hours later have the opposie. Also alot of times my blood pressure goes up really high like 163/149. But my pulse will be normal. How is it possible? I don't understad. Anyonoe?
