yes, hello Dr Lynne. I am a healthy 54 year female never had medical problems. In fact I am a vegetarian. Today i worked later than normal and ate a spicy dish. I do have braycardia slow heart rate that range between 38 and 45 beats. Thirty minutes after eating, I was driving home. I had really bad indigestion tried to belch. Then I felt light headed. I checked my heart rate on my phone and it stated my heart rate was approx 150. I drink water that helped me but that episode did frighten me. I just had a physical Jan this year everything was fine. I do have a slight headache.
