A defibrillator is a medical device that utilizes a strong pulsed current through the heart to eliminate arrhythmia and restore sinus rhythm, and is essential emergency equipment for the operating room.
The main purpose of defibrillators is to defibrillate adult and pediatric patients with serious arrhythmias such as ventricular fibrillation and other malignant ventricular arrhythmias.
It should be noted that it is contraindicated in people with sick sinus node syndrome, bradyarrhythmia due to digitalis overdose; atrial fibrillation, atrial flutter, and atrial tachycardia with high or complete conduction block; severe hypokalemia; and a large left atrium with atrial fibrillation lasting for more than a year and chronically low ventricular rate.
And the use of defibrillators may cause arrhythmia, low blood pressure and skin burns and other adverse reactions.
It is recommended that defibrillators should be used under the guidance of a doctor, and should not be used without authorization, and any discomfort that occurs after the use of defibrillators should be promptly notified to the doctor.
