Post-marketing Registration Study of Nifekalant Hydrochloride (NIF) Injection

Retrospective and Prospective single arm, observational study to evaluate efficacy and safety of NIF in the treatment of ventricular tachycardia and ventricular fibrillation. The information registration of the target population will be collected with the hospital HIS system or LIS system.

The recommended treatment plan for this study is from the usage and dosage of NIF. The clinician can make appropriate adjustments to the specific usage and dosage according to the patient's condition.

Load dose: Adults usually use 0.3mg/kg each time, under continuous ECG monitoring, the injection should be completed within 5 minutes, and the maximum dose should not exceed 0.5 mg/kg.

Maintenance dose: After load injection, the adult routine dose is 0.4 mg/kg/h under continuous ECG monitoring. The dosage could be appropriately increased or decreased according to the patient's reaction, but the maximum dose should not exceed 0.8 mg/kg/h.
