Arrhythmias
- Identify rhythm + hemodynamic stability first
- Unstable tachyarrhythmia → synchronized cardioversion
- Bradyarrhythmia → atropine/pacing as appropriate
- Stable therapy depends on rhythm mechanism
- Correct K/Mg, ischemia + drug triggers
- Antiarrhythmics can themselves be proarrhythmic
