Hello,

No, it does not cause reflex tachycardia, I checked and it is not listed as an adversed effect.-

Input
The vagus nerve( also called pneumogastric nerve, cranial nerve X, the Wanderer or sometimes the Rambler, is the tenth of twelve (excluding CN0) paired cranial nerves. Upon leaving the medulla between the olivary nucleus and the inferior cerebellar peduncle, it extends through the jugular foramen, then passing into the carotid sheath between the internal carotid artery and the internal jugular vein down below the head, to the neck, chest and abdomen, where it contributes to the innervation of the viscera. Besides output to the various organs in the body the vagus nerve conveys sensory information about the state of the body's organs to the central nervous system. 80-90% of the nerve fibers in the vagus nerve are afferent (sensory) nerves communicating the state of the viscera to the brain.)plays a role in (amongst other things) controlling the pulse. The vagus reflex is a reaction which can reduce the pulse rate. Intentionally inducing a vagus reflex is sometimes used to treat tachycardia . The following stimuli may produce the vagus reflex:

tensing the lower abdomen (similar to straining at stool)
gentle pressure on the closed eyes
a gulp of ice-cold water
splashing ice-cold water on the face
immersing the arms in ice-cold water
finger stuck down the throat
the insertion of an IV needle
cough or sneeze (involuntary or autonomic works best)
holding breath (after exhaling) Valsalva manoeuvre

Take care.-

CCBs (calcium-channel blockers) a side effect , one of many is reflex tachycardia.- Information is the key to open almost every door... with all due respect.-

The most smooth muscle selective class of CCBs are the dihydropyridines
amlodipine
felodipine
isradipine
nicardipine
nifedipine
nimodipine
nitrendipine

These can cause as contradictions or side effects the reflex tachycardia.-

Your question was very interesting to me , I just want to be able to go the extra mile... if you do not mind , with all my respect to you and your condition.-

Once again take care.-OK
