Is Diagnosis Of Incomplete RBBB In An ECG A Concern?

Yes, I am a 47 year old male who recently demonstrated incomplete RBBB on an ECG. I have always had normal ECGs and this was the first abnormality ever. The QRS complex showed 103 ms and a second EKG showed a QRS complex of 98 ms. Initially the technician said she put the lateral leads in the wrong position. I ve gotten conflicting reports of incomplete RBBB being insignificant finding, however I am still concerned. I am going for a sleep study. If positive and condition is related to OSA can the condition be reversed?

Hi,

As long as you have not any obvious cardiovascular disorder, and no evidence of coronary risk factors (I suppose your blood lipid profile, glucose metabolism have resulted OK, and also you are not a smoker), besides a borderline high normal blood pressure (140/85 mmHg could not classify as hypertension and doesn’t deserve medical treatment), then your ECG findings would not be considered problematic.

In such case, it is not considered a marker of any underlying myocardial ischemia.

You shouldn’t worry too much about!

But, if from your ordered echocardiogram results in some degree of left ventricular hypertrophy, then your average blood pressure values must have been much higher previously than the actual measured blood pressure.

Coming to this point hypertension would be considered a confirmed coronary risk factor and you need to follow further screening tests.

In that case, a cardiac stress test is recommended for investigating a hidden coronary disorder.

I would like to directly review your cardiac ultrasound (ECHO) report when it becomes available.

Please, could you upload your blood lipid profile report and any other medical test?

Also a prescription about any other present coronary risk factor (smoking? Glucose metabolism disorder? Obesity? Heredity for premature coronary artery disease? etc.).

Hope I have answered your query. Let me know if I can assist you further.

Regards,
Dr. Ivan R. Rommstein,
General Surgeon
