Heart Transplant with RBBB and PVCs

Dr. T Ask Doctor T Leave a Comment

Q:

I have heart transplant with pacemaker having RBBB and recently I had some frequent PVCs otherwise 5-10 per day.  Blood work, ECG and echo found normal.  Once I saw low frequency 86 bps inversion of waves (9 of them) on continuous recording. Are these symptoms to worry about?

A:

When was your pacemaker last checked? With all other tests normal, the next step is to make sure that your pacemaker is sensing & pacing properly. Another thing I am somewhat concerned about is that new arrhythmias may be a symptom of coronary artery disease in your transplanted heart. The way to examine this with an exercise ECHO, Coronary angiography, Nuclear (thallium/sestamibi)or     Dobutamine stress echocardiography, or an Intravascular ultrasound.
