My 38 yr. old physically fit, normal weight, cardio and wight lifting, motorcross racing husband has been short of breath for a few years. This has not actually been diagnosed as asthma, but he takes singulair and albuterol prn. It tends to be seasonal or related to air quality. Additionally, blood pressure has been in the 140's/80's. So not extremely high. He also takes weight lifting supplements (no steroids). The PMD did an EKG to be sure and found something needing further testing (did not say what). We then saw a cardiologist and the repeat EKG showed possible hypertrophy and/or enlarged heart. No murmur, no CHF. No symptoms of chest pain. We have had a chest film and labs and will be going for an echo and possible stress test. My question is what is the accuracy of this type of finding on EKG? Could 20 years of weight training cause this or would the asthma be a more likely cause?
