about six months ago my heart started to beat hard and fast.. it didnt hurt, i think it was a panic attack. I ended up worrying about the whole week noticed my heart more often and it was beating more faster. my Family doc sent me to emergency, where they did ECG. it showed that i had a inferior lateral Q wave. I did a Cardiac scan everything was fine, my holtor montor test showed that my heart beat ranges from 43 to 173. 173 was due tridmill exercise i did. It was when i was sleeping that my heart droped to 43. It showed that my resting heart rate is 100. And during one epsiode when sleeping my heart didnt beat for about 2.08 secs. My doc says this mormal. He also said that i shouldnt worry about the Q wave and focus on other test because that doesnt tell them i have had heart damage. it was concluded i had sinus tachycardia. I also have excessive anxiety, my family doctors say this could be cause of the tachycadia she has put me on propranolol. My Question is what does a inferior lateral Q wave mean if it does not due to heart damage. Why is my heart so slow when sleeping and fast during the day should i be worried about it. Is it possible to get panic attacks when exericing. What else can cause Sinus tachycadia that i shoould get my doc to check. So far i have dealt with 4 emergency docs and family doc and none of them answer these questions. Also i am over weight doc has asked me to loss weight.. which i am. Can this be a cause of my sinus tachycadia.
Sorry you are having so much trouble getting a clear medical answer. It is known that anxiety and worry can cause a lot of heart rhythm problems. This and your good test results suggests you have nothing to worry about and you should concentrate on getting the anxiety reduced.
One would expect the lowest HR to be when one is asleep. This may not be the case during a dream if the dream is upsetting/exciting, then the HR could go up. A HR of 43 is low, but your doctor said it and the measured 2 second stop is not a problem. I think I'd go with the doctor's expert conclusion.
