Usually 200+, but could be between 100-150. Your blood pressure in your peripheral vascular system could be elevated extremely, also causing stress on your heart during pre-load, thus making the heart work harder to compensate and maintain perfusion during the hypertensive episode. Also, regardless of heart rate, cardiac oxygen demand has a huge effect of myocardial performace and perfusion. Your systemic blood pressure could be high, and your heart relies on this peripherial blood pressure to oxygenate the heart itself; so if the myocardial oxygen supply is low, then damage to the heart can happen, regardless of cardiac output. Also your increased heart rate could be due to low blood pressure, or low blood volume. This is called reflex tachycardia, and is a compensatory effect, where your body is trying to increase its blood pressure, by increasing cardiac output. Regardless of etiology, you need to see a physician. They can determine the cause of the tachycardia, observe your cardiac activity (i.e. electrocardiogram) to see how well your heart is working, or what problems you may have in the heart itself. Good luck, I hope it is very minor, and that it will be easily treatable by you and your doctor.
