Guest guest Posted May 5, 2001 Report Share Posted May 5, 2001 I am getting really confused so if you have heard this before, please accept my apologies for repeating it. The Mayo Clinic (Dr. Low) recently had a study published in which they discovered autoantibodies to acetylcholine receptors on smooth muscle. This is much like myasthenia gravis in which the signals to voluntary muscles are blocked by autoantibodies, except that this affects non-voluntary muscles like the heart. My guess would be that sympathetic and parasympathetic (vagal) signals to the heart would be blocked at some or all of the various points where the nerves connect to the heart and that these connections might be intermittent. These nerves connect to multiple points in the heart to stimulate or depress cardiac activity. Suppose that the atrium got stimulated but the ventricle didn't, for example. Discussion?
