I recently got an ECG done that showed IRBBB, and after that, I had an echocardiogram and TMT, which both turned out normal. Should I be doing these tests every year? And do you know why the IRBBB showed up in my ECG? Is there any treatment I should consider for this?

Intermittent Right Bundle Branch Block (IRBBB) is a common finding in electrocardiograms and is usually considered a benign condition, especially if other cardiac tests such as echocardiogram (echo) and exercise stress test (TMT) are normal. It is not typically associated with any symptoms or specific treatment. In your case, since your echo and TMT results were normal, there may not be a need to repeat these tests every year unless your doctor specifically recommends it based on your overall health condition. IRBBB can sometimes be a normal variant or can be associated with underlying heart conditions, so it is important to follow up with your healthcare provider for further evaluation and guidance. If you do not have any symptoms and your other cardiac tests are normal, no specific treatment may be necessary for IRBBB. However, it is important to maintain a healthy lifestyle, including regular exercise, balanced diet, and avoidance of smoking and excessive alcohol consumption to promote overall heart health.
