I am a 32 year old male and my normal heart rate is very high (and it has always been high). When I am not exercising it would be some where close 120. And when I do exercise it can go up to 140-150. Do I have a heart problem or is this normal for some people? I did not realize this was a problem until I compared it to wife, her heart rate is less than 72 under normal condition and when she exercises it goes up to 92. Tachycardia is the medical term for an excessively rapid heartbeat.
You must schedule an appointment with your physician and explain your condition. Have you felt dizzy, tired, and/or cold? Your blood pressure will also be taken into consideration. Blood will be taken (if your doctor deems it necessary) to determine if your thyroid is functioning properly. Your heart will also be monitored. If nothing is wrong, other than the rapid heartbeat, there is nothing that can be done. I dunk my head in cold water occasionally if I am having an episode. If there is something wrong with your thyroid or heart your doctor will be able to advise you on what to do next.
