A member asked:

If you had heart block or sinus block would you still get sinus arythmia?

A doctor has provided 1 answer

Sinus arrhythmia: Sinus arrhythmia occurs proximal to sinus exit block. On the other hand, if there's sinus exit block then seeing that the sinus is very irregular is difficult as there are all degrees of exit block.
