- Bradycardia:Heart rate less than 60 beats per minute (bpm)
- Tachycardia:Heart rate greater than 100 bpm
| Name | Type | Description |
|---|---|---|
| Sinus Bradycardia | Bradycardia | Heart rate less than 60 bpm originating from the sinoatrial node |
| Sinus Tachycardia | Tachycardia | Heart rate greater than 100 bpm originating from the sinoatrial node |
| Atrial Fibrillation | Tachycardia | Irregular heart rate caused by disorganized electrical impulses in the atria |
| Ventricular Tachycardia | Tachycardia | Rapid heart rate originating from the ventricles |
| Ventricular Fibrillation | Tachycardia | Chaotic and ineffective heart rhythm originating from the ventricles |
