3.8 Group 5: Regular rhythms with 0.15

1.0 and PR range > 60 ms
Say: “sinus rhythm with complete AV block; idioventricular escape rhythm”
if: heart rate < 40 BPM
and QRS duration

120 ms
Say:
“sinus rhythm with complete AV block; accelerated idioventricular escape rhythm,”
“ consider AV junctional rhythm with aberrant ventricular conduction”
if: 40  heart rate < 60 BPM
and QRS duration

120 ms
Say:
“sinus rhythm with block and/or interference in the AV junction;”
“ accelerated AV junctional rhythm with aberrant ventricular conduction,”
“ consider ventricular tachycardia”
if: 60

heart rate < 100 BPM
and QRS duration  120 ms
Say:
“sinus rhythm with block and/or interference in the AV junction;”
“ AV junctional tachycardia with aberrant ventricular conduction,”
“ consider ventricular tachycardia”
if: heart rate

100 BPM
and QRS duration

Say:
“supraventricular tachycardia with block and/or interference in the AV junction”
if: 100  heart rate < 140 BPM
and QRS duration < 120 ms
Say:
“supraventricular tachycardia,”
