Introduction
The indication for synchronized electrical cardioversion is tachyarrhythmia, which can restore sinus rhythm after defibrillation. The electrical pulse delivered during the procedure must be synchronized with the patient's cardiac cycle. Electrical cardioversion, also known as a defibrillator or cardiac resynchronization device, is a medical electronic apparatus used to rescue and treat arrhythmias. Typically, patients can regain normal sinus rhythm following electrical cardioversion.
The indications for synchronized electrical cardioversion are rapid arrhythmias that can restore sinus rhythm after defibrillation. The electrical pulse delivered during cardioversion must be synchronized with the patient's cardiac cycle. Electrical cardioversion, also known as a defibrillator or cardioverter, is a medical electronic device used to rescue and treat arrhythmias. The four indications for synchronized electrical cardioversion are:
1. Ventricular fibrillation (VF) – ventricular flutter
This is an absolute indication for electrical cardioversion; however, direct current (DC) cardioversion cannot be performed synchronously in this case, so unsynchronized defibrillation must be used.
2. Chronic atrial fibrillation
Persistent atrial flutter also requires synchronized cardioversion.
3. Paroxysmal supraventricular tachycardia (PSVT)
If conventional treatments are ineffective and there is significant hemodynamic instability, it may be due to pre-excitation syndromes or sinus tachycardia.
4. Atrial flutter
Synchronized cardioversion is indicated for atrial flutter with 1:1 conduction.
Typically, patients can restore normal sinus rhythm after electrical cardioversion. Additionally, in cases of unsynchronized defibrillation, the aforementioned methods can be applied when the heart has stopped beating, in order to buy critical time.
