I haven't from him in about a week I hope he is ok. thanks so much for the info
I'm also sorry to read about your brother. There must be other heart issues, though, because a complete heart block is 100% treatable with either a permanent or temporary pacemaker. If he had an MI (heart attack) or several that destroyed his heart muscle, then a pacemaker would fire but the muscle could be too damaged to respond and pump appropriately, I suspect that he has coronary artery disease as well as electrical issues.
Im so sorry to hear that sadie. I hate to see people suffering from such things. A third degree AV block, also known as complete heart block, is a defect of the electrical system of the heart, in which the impulse generated in the atria (typically the SA node on top of the right atrium) does not propagate to the ventricles.
