Hi, this is Jamie Glick. I'm here to talk about heart palpitations in running. Heart palpitations in running can be a very common occurrence but it could also be a very serious occurrence and you need to know to take appropriate action. A heart palpitation is simply an abnormal beating of the heart and you may feel it when you're running as pressure in your chest, a fullness in your throat, or an uneasy feeling that you get that you know your body is just not responding right the way it normally does when you're running. The heart palpitation can be caused by a number of things: stress, anxiety, too much caffeine, a side effect of one of your medications, being at a higher elevation, can also cause a heart palpitation, and heart palpitations mainly occur after the run when the adrenaline rate is still high and your heart is in a state of transition from high to recovery to low. If you feel faint, dizzy, or short of breath that's another reason to seek medical attention. While that might not require a trip to the ER or the hospital you do want to consult you doctor about this. Most of the time a heart palpitation is normal occurrence that runners get from time to time and not a cause for alarm but when you do have one of those risk factors you want to seek medical attention make sure you're taken care of.
