Explanation:
Detailed explanation-1: -Vagus nerve stimulation (VNS) is known to reduce the heart rate, and hence may be a non-pharmacological alternative for the management of persistent sinus tachycardia. To precisely regulate the heart rate using VNS, closed-loop control strategies are needed.
Detailed explanation-2: -They are constantly active, producing a rhythm of 60 – 80 beats per minute. If the vagus nerve was lesioned, the resting heart rate would be around 100 beats per minute.
Detailed explanation-3: -Stimulation from the left mid-cervical vagus nerve most commonly causes voice alteration, cough, dyspnea, dysphagia, and neck pain or paresthesias.
