Doublet or sequence of non-dominant complexes
Say: “doublets of multiform premature ventricular complexes”
or
“sequence of multiform premature ventricular complexes”
if: more than one type of non-dominant consecutive complexes
Say:
“doublets of supraventricular escapes with aberrant ventricular conduction, cause?”
or
“sequence of supraventricular escapes with aberrant ventricular conduction,”
“ cause? eg SA block?”
if: one type of non-dominant consecutive complexes
and QRS duration non-dominant complexes

ULN + 20 ms
and RR ratio > 1.2
Say:
“doublets of ventricular escapes, cause?”
or
“sequence of ventricular escapes, cause? eg AV block?”
if: one type of non-dominant consecutive complexes
and QRS duration non-dominant complexes > ULN + 20 ms
and RR ratio > 1.2
Say:
“doublets of aberrantly conducted complexes”
or
“sequence of aberrantly conducted complexes”
if: one type of non-dominant consecutive complexes
and 0.9 < RR ratio

1.2
Say:
“doublets of premature supraventricular complexes with”
“ aberrant ventricular conduction”
or
“sequence of supraventricular complexes with aberrant ventricular conduction”
if: one type of non-dominant consecutive complexes
and QRS duration non-dominant complexes

ULN + 20 ms
and RR ratio

0.9
Say:
“doublets of premature ventricular complexes”
or
“sequence of ventricular complexes”
if: one type of non-dominant consecutive complexes
and QRS duration non-dominant complexes > ULN + 20 ms
and RR ratio

0.9
Alternating dominant and non-dominant complexes
Say: “bigeminal rhythm, consider escape capture bigeminy”
if: alternating dominant/non-dominant complexes in the whole recording
and one type of non-dominant consecutive complexes
and QRS duration non-dominant complexes

ULN + 20 ms
and RR preceding non-dominant < RR preceding dominant complexes
and no P preceding dominant QRS complexes
Say:
“as a bigeminal rhythm”
if: alternating dominant/non-dominant complexes in the whole recording
and failure to meet one or more of the other criteria above
Say:
“episode of bigeminal rhythm”
if: alternating dominant/non-dominant complexes for at least three consecutive times but not in
the whole recording
