3.10 Group 7: Regular rhythms with P/QRS > 1.0 and PR range > 30 ms
Say: “atrial tachycardia”
if: 270

shortest PP interval < 370 ms
Say:
“sinus tachycardia”
if: 370

shortest PP interval < LLN
Say:
“sinus rhythm”
if: shortest PP interval

LLN
Say:
“with second degree AV block at 2:1 conduction ratio”
if: shortest PR interval > 120 ms
and 1.75 < P/QRS ratio

2.0
If the criteria for a 2:1 AV block are not fulfilled, an AV dissociation due to block or interference is
assumed.
Say: “with complete AV block”
“idioventricular escape rhythm”
if: QRS duration

ULN + 20 ms
and heart rate < LLN – 20 BPM
Say:
“with complete AV block”
“accelerated idioventricular escape rhythm, consider”
“AV junctional rhythm with aberrant ventricular conduction”
if: QRS duration

ULN + 20 ms
and LLN – 20 BPM 
heart rate < LLN
Say:
“with block and/or interference in the AV junction”
“accelerated AV junctional rhythm with aberrant ventricular conduction,”
“consider ventricular tachycardia”
if: QRS duration

ULN + 20 ms
and LLN

heart rate < ULN
Say:
“with block and/or interference in the AV junction”
“AV junctional tachycardia with aberrant ventricular conduction,”
“consider ventricular tachycardia”
if: QRS duration

ULN + 20 ms
and heart rate

ULN
Say:
“with complete AV block”
“AV junctional escape rhythm”
if: QRS duration < ULN + 20 ms
and heart rate < LLN
Say:
“with block and/or interference in the AV junction”
“accelerated AV junctional rhythm”
if: QRS duration < ULN + 20 ms
and LLN

heart rate < ULN
Say:
“with block and/or interference in the AV junction”
“AV junctional tachycardia”
if: QRS duration < ULN + 20 ms
and heart rate

ULN
