Pacemaker defibrillator costs a total of 80 to 90 thousand dollars. Pacemaker defibrillator is a device with pacing and defibrillation functions, clinically it is mainly used for the prevention of malignant arrhythmia, the cost of the procedure is about 80,000~90,000 RMB, the exact price may fluctuate from patient to patient in different levels of hospitals. Malignant arrhythmia can lead to syncope and even sudden death. The common arrhythmia is paroxysmal ventricular tachycardia, which can be seen in arrhythmogenic right ventricular cardiomyopathy, long QT interval syndrome, etc. For patients with symptomatic episodes, implantation of a pacemaker-defibrillator is required. For patients with episodic syncope, routine dynamic electrocardiograms should be performed to determine whether paroxysmal ventricular tachycardia has occurred, and if indicated, surgical treatment should be performed under the guidance of a physician, with the specific costs based on the hospital.
