Incomplete Right bundle branch block and GERD

[bubbles410]

I have suffered terrible gerd and esophigial spasms for four months.  After being on pantoprazole 2 time per day  and domperidone the spasm stopped however the burning continued from by back to my chest.  My GI specialist reommended 10 mg of amitriptyline.  After 2 days of taking it the burning stopped but I developed the worst upper back and chest pain.  This was different from the first pain which was up and down.  This new pain was across my upper back and chest.  After 7 days I realized that this occured when I started the amitripyline and stopped taking the amitripyline and the pain went away.  I thought I was cured.  However the first burning pain has returned along with the sore throat.  I have been diagnost with an incomplete right bundle block branch.  Could the amitriptyline have  caused the second chest and back pain due to the IRBBB?

I had a stress test the week before I started the amitriptyline and it showed normal except they told me I had the incomplete RBBB which they were not concerned about.  I wanted to start the amitriptline again to see if it would make the burning go away again, However I read on a web site that you should not take amitriptyline if you have any electrical abnormalities it your heart.  This got me to thinking, maybe that is why I had the seconday pain in my chest and back.  Is that possible?  I was afriad to start the amitriptyline again.

I don't think so. The IRBB does not usually cause chest pain by itself, but can be seen in the setting of a heart attack by infarcting part of the right bundle. The amitriptyline does have anticholinergic effects and can cause coronary ischemia in patients following heart attacks. How sure are you that the pain you had was secondary to esophageal spasm and not heart disease?
