AV synchrony in patients with high PVC burden

Patient # AV conduction status Sinus node status PVC burden AV synchrony (%)
1 1:1 Normal 35.8 63.4
2 Third degree AV block Normal 9.2 81.9
3 Intermittent third degree AV block Normal 8.3 5.9a
4 Third degree AV block Normal+PACs 4.6 92.5
5 Second degree AV block Sinus brady 5.6 95.4

Abbreviations: AV, atrio‐ventricular; PVC, premature ventricular contraction.

This patient had a long P‐R interval (median, 375 ms). The pre‐defined definition of AV synchrony was P‐R < 300 ms, which led to the low AV synchrony.
