| Wide complex tachycardia QRS ≥ 120ms | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Do the following simultaneously: - Assess and support ABC's as needed - Give oxygen - Monitor ECG, BP, oxymetry - Identify and treat reversible causes | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Is the patient stable? Unstable signs include: - Chest pain - Congestive heart failure - Hypotension - Loss of consciousness - Seizures | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Yes | No | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Is the rhythm regular? | Immediate synchronized cardioversion -Establish IV access - Give IV sedation if the patient is conscious - Consider expert consultation | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Regular rhythm | Irregular rhythm | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Ventricular tachycardia or uncertain rhythm? | SVT with aberrancy? | Afib with aberrancy? | Pre-excited Afib (Afib + WPW)? | Recurrent polymorphic VT? | Torsade de pointes? | ||||||||||||||||||||||||||||||||||||||||||||||||||||||
| - Give amiodarone 150 mg IV over 10 min - Repeat amiodarone as needed for a maximal dose of 2.2g/24h - Prepare for elective synchronized cardioversion | - Give adenosine 6 mg rapid IV push - If no conversion give 12 mg IV push - May repeat 12 mg dose once | - Consider expert consultation - Control rate e.g diltiazem or beta blockers Use beta blockers with caution in pulmonary diseases or CHF | - Consider expert consultation - Avoid AV nodal blocking agents e.g adenosine, digoxin, diltiazem and verapamil - Consider amiodarone 150 mg IV over 10 min | Consider expert consultation | Load with Magnesium 1-2 g over 5-60 min, then infusion | ||||||||||||||||||||||||||||||||||||||||||||||||||||||
