Resuscitation guidelines are not universal. Focus is on exact numeric differences. Compare drug doses and energy settings. Differences impact global practice. Bradycardia: Atropine Dosing Difference is in the first push dose. AHA starts with 1 mg IV atropine. AHA repeats every 3 to 5 minutes. ERC starts lower at 0.5 mg IV atropine. ERC repeats every 3 to 5 minutes. Maximum total dose for both is 3 mg. AHA favors reaching therapeutic level faster. ERC favors gentler, titrated approach. Stable SVT: Adenosine Dosing First dose is 6 mg IV for both. Second dose is 12 mg IV for both. Doses one and two are identical. ERC specifically adds a numeric third dose. ERC third dose is 18 mg IV. AHA protocol stops defining doses after 12 mg. After 12 mg fail, AHA moves to cardioversion. ERC formalizes higher dose clinical judgment. VT/Wide Complex Tachycardia: Amiodarone Load This is the biggest dosing gap. AHA loading dose: 150 mg IV. AHA load given over 10 minutes. AHA maintenance infusion: 1 mg/minute for 6 hours. ERC loading dose: 300 mg IV. ERC load given over 10 to 20 minutes. ERC initial dose is double AHA's. ERC maintenance: 900 mg total over 24 hours. ERC tries to hit therapeutic blood levels faster. AHA's 150 mg is a more cautious step. Cardioversion: Atrial Fibrillation Energy Starting points for energy delivery differ totally. AHA recommends starting at 200 Joules. AHA may escalate stepwise if needed. ERC recommends maximum defibrillator output immediately. ERC bypasses starting lower and escalating. ERC favors speed and maximizing shock success. Higher energy shocks are more effective initially. Cardioversion: Other Rhythms Energy Atrial flutter/PSVT: ERC suggests lower initial energy. ERC range: 70 Joules up to 120 Joules. Monomorphic VT with pulse: AHA starts at 100 Joules. Monomorphic VT with pulse: ERC pushes higher. ERC range: 120 Joules up to 150 Joules. Polymorphic VT: AHA uses unsynchronized high energy shock. Guideline Philosophy Summary Numeric differences are critical divergences. ERC often favors immediacy and higher initial impact. ERC uses more drug and more Joules. ERC aims for stability faster. AHA favors standardized step-by-step approach. AHA approach is often more cautious.
