Ventriculophasic sinus arrhythmia is a non-respiratory sinus arrhythmia seen in complete AV block.
The PP interval enclosing a QRS complex is shorter than a PP interval not enclosing a QRS.
The Mechanism
The proposed mechanism is the increased blood flow into the SA node artery during ventricular systole stimulating it to produce an early pacemaker activity and thus shortening the sinus cycle length.
Clinical significance : None for the patient Academic purpose for the students

The irony of medicine is unlimited ! 100 years of active clinical research failed to find a specific cure for the rhino virus mediated common cold.In fact US Govt stopped funding for this .
While , complete cure is possible for many of the cancers, especially hematological ones !
Message
In medicine there are thousands of disorder which have no cure !
Cancers , constitute only a fraction of them !
