Isolated non-dominant complexes
Say: “premature ventricular complexes with variable coupling intervals,”
“ consider ventricular parasystole ”
if: QRS duration non-dominant complexes > ULN + 20 ms
and coupling interval range > 80 ms
Say:
“multiform premature ventricular complexes”
or
“premature ventricular complexes”
if: QRS duration non-dominant complexes > ULN + 20 ms
and coupling interval range

80 ms
and RR ratio < 0.9
Say:
“ventricular escapes, cause? eg AV block?”
if: QRS duration non-dominant complexes > ULN + 20 ms
and coupling interval range

80 ms
and RR ratio > 1.2
Say:
“aberrantly conducted complexes”
if: 0.9 < RR ratio

1.2
Say:
“premature supraventricular complexes with aberrant ventricular conduction and”
“ variable coupling intervals, consider supraventricular parasystole”
if: QRS duration non-dominant complexes


and coupling interval range > 80 ms
Say:
“supraventricular escapes with aberrant ventricular conduction,”
