| Ventricular Tachycardia | regular (mostly) | 60-100 bpm | 110-250 bpm | ventricle (VT) | AV-dissociation | no rate reduction (sometimes accelerates) | |
| Ventricular Fibrillation | 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) | ||
