Two rounds of DSD were performed by placing additional pads on the patient’s anterior-posterior areas and sequentially applying the maximum energy setting. Although 10 defibrillations were administered over 20 minutes, there was no response. The initial electrocardiography showed markedly elevated ST-segment on V1–V5 leads, and VF arrest occurred. A 51-year-old man visited the emergency department with chest pain. We report a case of RVF that was successfully resuscitated with double sequence defibrillation (DSD). However, the mortality rate increases when refractory ventricular fibrillation (RVF) occurs.
In cardiac arrest, if the initial rhythm is ventricular fibrillation (VF) or pulseless ventricular tachycardia, the survival rates are high and good neurologic outcomes are expected.
