Te ANS kontroluje heart rate primarily via thee sinoatrial node, thee heart 's natural pacemaker. Sympathetic stymulation akcelerates heart rate, while parasympathetic (vagal) input slows it down. Autonomic neuropathy can incorsiir both arms of this system, leading to a variety of rhythm difficinations and functival limitations.
