May indicate incomplete AV valve closure during isolated atrial beats in complete block; leaves open prevalence and relevance beyond this case.
Isolated atrial contractions in patients with total A-V block lead to atriogenic reflux due to incomplete A-V valve closure, whereas ventricular contractions produce efficient closure.
Rutishauser et al. (1966) studied this question.
