Tentative Dilated Right Ventricle, Done Electrocardiogram, Normal Stress Test. Family History Of Bad Heart. Worried.
Thank you for your query.
Right bundle branch block on the ECG can be present due to many causes. It can be present as a normal variation also. It can also be present if there is any strain or dilatation of the right ventricle (the chamber that pumps impure blood to the lungs for oxygenation) or if there are disturbances in the electrical conduction pathways on the right side of the heart.
An echocardiogram, chest x-ray and some blood tests may be done to confirm the findings and to know if there is any specific cause for this.
I would like you to upload the ECG and if possible, the findings of the echocardiogram on this website, so that I can analyze them and give you a more specific answer.
Since the stress test is normal and since he appears to be otherwise doing well without any symptoms, there may not be anything serious. However, it is worth investigating to identify any possible abnormalities and take corrective action depending on the diagnosis reached.
I hope this answers your query. Please upload the ECG and echo findings for me to give you a more detailed answer.
With regards,
Dr RS Varma
