What type of electrical defibrillation is used for ventricular fibrillation?

Generally, ventricular fibrillation is treated with unsynchronized direct current (DC) defibrillation. Details are as follows:

Ventricular fibrillation is a severe arrhythmia that often leads to cardiac arrest and sudden death. Electrical defibrillation is currently an effective treatment for ventricular fibrillation, capable of restoring normal heart rhythm by delivering an electric current, typically using unsynchronized DC. At present, there are two commonly used types of defibrillators: manual defibrillators and automated external defibrillators (AEDs). Manual defibrillators are professional medical devices typically used in emergency departments, intensive care units, and similar settings. They usually require conductive gel electrodes placed on the patient's chest to deliver the electrical current to the heart and restore normal rhythm. Automated external defibrillators are portable devices designed for use by laypersons during emergencies. Equipped with voice prompts and visual instructions, AEDs help users perform the procedure quickly and correctly, thereby improving treatment outcomes.

It should be noted that defibrillation for ventricular fibrillation must be performed in emergency situations; therefore, adequate preparation and training beforehand are essential to ensure correct and timely operation. Additionally, it is important to select the appropriate defibrillator and adjust settings according to the patient’s specific condition to achieve optimal therapeutic results.
