Hello doctor, My boyfriend is 24 years old. Being a fitness trainer, he does not take any drugs. He has been getting chest pain for the past four months and sometimes lightheadedness. He went to the doctor and had done a blood test which came back normal. His blood pressure is low, and he had a 24-hour Holter monitoring and ECG. The results came back as second-degree heart block four times in 24 hours. Our appointment with cardiologist is after a month. I am worried because he feels weaker when he exercises and the pains are more frequent. Not sure what we can do in the meantime or what is causing it.
Hello. I understand your concern. I want to explain that when we are in front of a cardiac conductance abnormality in an young adult first, it is necessary to exclude an infectious and inflammatory disease, like Lyme disease, sarcoidosis, and other cardiac issues, like myocarditis, and anomalous coronary artery, etc. It is necessary to undergo a full blood test panel and a cardiac ultrasound test. For a more detailed cardiac tissue characterization, it is necessary to undergo a cardiac magnetic resonance imaging test (CMR). Meanwhile, I recommend that your friend refrains from competitive sports and any excessive physical exertion. I hope it is helpful for you.
