| Ventricular tachycardia | regular (mostly) | 60-100 bpm | 110-250 bpm | ventricle (VT) | AV-dissociation | no rate reduction (sometimes accelerates) | |
| ventriclefibrilleren | irregular | 60-100 bpm | 400-600 bpm | ventricle (VT) | AV-dissociation | none | |
| Ventricular flutter | regular | 60-100 bpm | 150-300 bpm | ventricle (VT) | AV-dissociation | none | |
| AIVR | regular (mostly) | 60-100 bpm | 50-110 bpm | ventricle (VT) | AV-dissociation | no rate reduction (sometimes accelerates) | |
| Torsade de pointes | regular | 150-300 bpm | ventricle (VT) | AV-dissociation | no rate reduction (sometimes accelerates) | ||
| Supraventricular tachycardia with block | (ir)regular depending on SVT | 150-250 bpm | 75-200 bpm | atria (SVT) | absent | temporary increased AV-block (eg 4:1) | |
| AVRT - antidrome | regular | 150-250 bpm | 150-250 bpm | circular: bypass - atria - av-node - ventricles | RP < PR | stops | |
