I have been referred to a cardiologist because I have an irregular heartbeat which is causing shortness of breath and is uncomfortable. My ECG concluded normal LV and RV function with a mile left atrial enlargement (42 mm). In the past 15 months, Ive lost 25 lbs, ran a half marathon in December, exercising (with a trainer) 4 days a week, and eating healthier than I have since college (I am 37 years old). My grandmother (deceased) had and my mother has an irregular heartbeat so I feel it was inherited. I will see the cardiologist tomorrow but wonder how Ive not truly been affected with the signs and symptoms listed on most websites and in most books. I enjoy exercising and beginning to Crossfit train (heavy resistance training) while continuing to jog/run (to include half marathons). My worry is that I would need to decrease training. I read LAE is treatable with medication. Is it possible for me to continue training/exercising whether or not I am placed on medication? Im just beginning to feel really good with my exercise regimen and still need to lose 15 lbs. This is a huge concern as again, I would think I am healthier now than Ive been in a while. Thank you for your response.
You have family history of irregular heartbeat means may be some accessory pathways may be there in your heart leading to irregular heartbeat, and you check with other investigations and rule Out this condition and AF may be due to this reason or dilated cardio myopathy in your family
