My heart rate is normally in the 70-80 range and tachycardia has never been an issue for me before. Earier tonight, my heartrate went up to 185 for about 30 minutes, at a time I wan t particularly stressed- in fact I was relaxed, watching a TV comedy stretched out on my recliner. Fortunately, it responded well to some interventions I found on line and is now back down to 73. Although I do have hypertension, at the time it started my BP was in the normal range, but about 15 min after it started, my BP was up to about 175/110. So my question is, at what point should I go to the hosp. if this recurrs?
