yeah but there are nerves involved ... maybe as Karlinohio said there is degraded response or something... but tell me how a heart transplant works without nerve impulses? I might understand lung or kidney at reduced capability but hearts don’t make sense without nerves
The heart just wants to beat. From Cleveland Clinic: Heart Beat:
1. SA node (sinoatrial node) known as the hearts natural pacemaker The impulse starts in a small bundle of specialized cells located in the right atrium, called the SA node. The electrical activity spreads through the walls of the atria and causes them to contract. This forces blood into the ventricles. The SA node sets the rate and rhythm of your heartbeat. Normal heart rhythm is often called normal sinus rhythm because the SA (sinus) node fires regularly.Search for "denerverated heart" and see far more than I can understand.2. AV node (atrioventricular node) The AV node is a cluster of cells in the center of the heart between the atria and ventricles, and acts like a gate that slows the electrical signal before it enters the ventricles. This delay gives the atria time to contract before the ventricles do.
3. His-Purkinje Network This pathway of fibers sends the impulse to the muscular walls of the ventricles and causes them to contract. This forces blood out of the heart to the lungs and body.
4. The SA node fires another impulse and the cycle begins again.
It looks like not having nerves attached just allows the heart to free run without any feedback from the brain.
