I have been having a very hard heartbeat several times a day . When this happens my head on the right temple starts to hurt and I have to catch my breath. I went to the urgent care today, they did a chest X-ray and an EKG. Everything was fine except that heart rate was 103. I ve had an extra heartbeat that happens two to three times a week that my cardiologist knows about and hasn t been concerned. But this is a very hard heart beat and is happening at least a dozen times a day along with the other symptoms that I mentioned before. The extra heart beats that I had had before didn t have any other symptoms with them. Not sure what to do but I m not feeling well.
