| External pacing | - Bradycardia - NCT, haemodynamically unstable - Contraindication for asystole, PEA, overdrive pacing of a ventricular dysrhythmia - Complications: pain, discomfort, anxiety, failure to capture |
| Broad complex tachycardias | - VT or SVT with aberrant conduction - If in doubt, treat as VT Irregular? Most likely AF with a BBB Do not rule out AF with WPW |
| Synchronised cardioversion | Method of restoring normal rhythm in patients presenting with a rapid ventricular rate associated with compromised cardiac output (symptomatic) - Pulsatile VT, SVT, AF, Aflutter |
