Multiple Choice

Which arrhythmias are an appropriate indication for synchronized cardioversion in an unstable patient?

• Sinus tachycardia

• Ventricular fibrilllation

• Atrial fibrillation with rapid ventricular response

• First-degree AV block.

Multiple Choice

What is the primary purpose of synchronizing the cardioversion shock with the R-wave of the patient's ECG?

• To reduce the risk of skin burns

• To synchronize breathing with the shock delivery

• To prevent delivering the shock during the T-wave

• To ensure the shock is delivered at the correct energy level.

Fill in the Blank

Cardioversion is contraindicated in ____________ arrhythmias, which require immediate defibrillation instead.

Cardioversion

​When to consider Cardioverting your Patient.

1. Hemodynamically Unstable Tachyarrhythmias:

   • Signs of instability: Hypotension, altered mental status, signs of shock, chest pain, or heart failure.

   • Arrhythmias: These include supraventricular tachycardia (SVT), atrial fibrillation (AF) with rapid ventricular response, atrial flutter, and certain types of ventricular tachycardia (VT) with a pulse.

2. Symptomatic Tachyarrhythmias:

   • When tachyarrhythmias cause significant symptoms but are not immediately life-threatening.

   • Symptoms can include palpitations, shortness of breath, lightheadedness, syncope, or significant fatigue.
