I have sfautononmic neuropathy. is normal sinus rhythm with frequent ectopic beats serious? what about significantly reduced sympathetic response to valsava technique and mild/mod decrease baseline autonomic tone/variability in heart rate?

With respect to ectopy, we'd have to have results of an outpatient Holter Monitor to determine whether there are PAC's or PVC's or both, how many per 24 hours, all single or some runs, with or without exercise, symptomatic or not. The very initial effect of Valsalva is a brief stimulation of the sympathetic nervous system but the main effect, through the vagus nerve, is a parasympathetic response
