摘要： A system for VT localization comprises an electrocardiograph (ECG) device for detecting electrical signals of a ventricular fibrillation event in a patient and producing ECG data, a localizer, and a display device. The localizer comprises a memory and a processor, the memory storing a model and one or more parameters of the model. The memory further stores instructions that when executed by the processor cause the processor to receive the ECG data, and generate a determination indicating whether a detected VT signal arose from an endocardial surface or epicardial surface based on signal averaged waveform for each of the leads. The display device is configured to output the determination, which can also be communicated to follow-on provider systems.
