ICD and Left Bundle Branch

Posted by lizzyprescott @lizzyprescott, Sep 22 12:12am

I'm meeting with the Dr in a few weeks re: the ICD. My troubles started about 8 weeks ago...admitted with stroke symptoms and MRI revealed a shower affect (?) stroke. Also revealed was 12% EF with Left Ventricle issues. They figure it's from a virus as I have no symptoms of heart failure. I've currently got the Zoll defibrillator and I'm waiting for my EF to improve further to get the implant. My EF is now 30%. My question...is Left Bundle Branch going to interfere with the implant?

Interested in more discussions like this? Go to the Pacemaker & ICDs Support Group.

I can’t think of a reason why it would. Of course, ask your EP. Your ICD should continue to protect you from any dangerous arrhythmias regardless of the source of the problem.

Lizzyprescott, If you have a left bundle branch block, that means that your two ventricles are not receiving the electrical signal sequentially affecting your ejection fraction. An electrophysiologist experienced in a procedure called Left Bundle Branch conduction Area Pacing (LBBAP) may be able to capture the left bundle block to allow your heart to use it’s natural electrical signal allowing your to heart beat rhythmically in sequence without delay, a QRS duration as seen on an ekg, hopefully increasing your ejection fraction. Biventriculsr Pacing has been and still is used, but LBBAP is the preferred method by excellent electrophyiologists that have expertly mastered the technique of placing one of the leads in the septum between the ventricles. My husband had the procedure done successfully. It was an outpatient procedure with an easy recovery. Research and inquire of your doctor to determine if this may benefit you. If you are waiting to get an ICD implanted, my understanding is that it is used to deliver shocks if you have ventricular tachycardias and does not help left bundle branch block. Please do research and ask lots of questions of your cardiologist and a referral to an experienced well respected electrophysiologist with fantastic reviews. Just an idea because I’m not a medical doctor or a health practitioner.
