question: Hi doctor, I had a bad episode of SVT. It was the first major episode. The heart rate was above 200 bpm. I rushed to emergency, today is the fifth day, and still, I have tightness in the chest, shortness of breath and pain in the chest that come and go. Is this normal? I am a 30-year-old female. My weight is 70 kg and height is 165 cm. I am not on any medication yet. I have a history of high anxiety. I had a sudden onset of fast heart rate around once or twice a few years before. I have white coat hypertension. Blood tests taken in the Emergency Unit came back normal.
