Direct current cardioversion: indications, techniques, and recent advances

Area of Science:

• Cardiology
• Critical Care Medicine

Background:

• Direct current cardioversion/defibrillation is a key intervention for intensivists.
• Its emergent use can be life-saving in critical situations.

Purpose of the Study:

• To review the appropriate application of direct current cardioversion in critical care.
• To emphasize cautious use in elective scenarios and highlight alternatives.

Main Methods:

• Review of current clinical practices and literature regarding direct current cardioversion.
• Discussion of patient selection criteria and procedural techniques.

Main Results:

• Emergent direct current cardioversion is a vital, potentially life-saving procedure.
• Elective cardioversion necessitates careful patient selection and technique.
• Futile, repetitive attempts should be avoided.

Conclusions:

• Direct current cardioversion is an essential tool in critical care.
• Judicious use, focusing on patient selection and technique, is paramount for elective procedures.
• Addressing arrhythmia precipitants may offer a safer, more effective strategy than repeated cardioversion attempts.
