I've asked my doctors repeatedly if the vagus nerve would have something to do with my PVCs. I also take my pulse and can feel the skipped beats. For me, coconut oil, coconut milk and whole coconut affects me this way. I also felt heart palpitations and a heavy feeling in my chest. And because all of this i am not able to give full attendance in linux+ classes. Also i have missed my oracle certification and vmware exam. Please if you know about this disease and have any treatment then let me know.
