Should jewelry be removed before direct‑current cardioversion?

Jewelry Removal for Direct-Current Cardioversion

Jewelry does not need to be removed for direct-current cardioversion (DCCV), as there is no evidence-based requirement or guideline recommendation mandating its removal.

What the Guidelines Actually Address

The major cardioversion guidelines from the ACC/AHA/ESC comprehensively detail procedural safety considerations, including:

• Paddle positioning and energy requirements 1
• Anticoagulation protocols [1, @14@]
• Management of patients with implanted cardiac devices 1, 2
• Electrolyte optimization (particularly potassium) 1
• Digitalis toxicity screening 1
• Synchronization techniques 1, 2

Notably absent from any guideline is any mention of jewelry removal as a safety requirement or recommendation 1.

The Practical Reality

What Actually Matters for Electrical Safety

The critical safety considerations for DCCV focus on:

• Proper paddle placement: Anterior-posterior configuration is preferred, especially in patients with pacemakers, with paddles positioned to optimize current pathway through the myocardium 1, 2
• Adequate skin contact: Ensuring good electrode-to-skin interface to prevent skin burns 3
• Synchronization: Delivering shocks synchronized to the QRS complex to prevent ventricular fibrillation 1, 2
• Energy selection: Starting with appropriate energy levels (typically 100-200 J for atrial fibrillation/flutter depending on waveform) 2

Why Jewelry Is Not Addressed

The absence of jewelry removal from evidence-based guidelines reflects several realities:

• Modern cardioversion uses self-adhesive electrode pads rather than handheld paddles, which are placed on the chest wall away from typical jewelry locations 2
• The electrical current pathway is directed through the myocardium between the two electrodes, not dispersed across the body surface 1
• Documented complications of DCCV include thromboembolism, arrhythmias, and skin burns at electrode sites—not jewelry-related injuries 1, 3

Common Pitfalls to Avoid

Do not delay urgent or emergent cardioversion to remove jewelry 1. The guidelines emphasize immediate cardioversion for:

• Hemodynamic instability 1
• Ongoing myocardial ischemia 1
• Symptomatic hypotension or heart failure with rapid ventricular response 1

In these situations, any delay increases morbidity and mortality risk 1.

What Actually Requires Attention

Focus procedural preparation on evidence-based safety measures:

1. Verify adequate anticoagulation (≥3 weeks prior for AF ≥48 hours duration, or perform TEE) 1
2. Confirm normal serum potassium to prevent ventricular arrhythmias 1
3. Exclude digitalis toxicity through clinical assessment, not just serum levels 1
4. Interrogate implanted cardiac devices before and after the procedure if present 1, 2
5. Ensure proper sedation for conscious patients 1
6. Position electrodes optimally (anterior-posterior preferred, especially with pacemakers) 1, 2

The Bottom Line

Jewelry removal is not an evidence-based requirement for DCCV and should not delay necessary cardioversion. Clinical attention should focus on the well-established safety protocols that actually impact patient outcomes: anticoagulation status, electrolyte optimization, device interrogation when applicable, and proper electrode positioning 1, 2.
