In case of cardiac arrest is there allways VT before Vfib. Can the ICD distinguish between VT and Vfib or is it based on the rate/beats | ||

There is not always VT before Vfib The ICD distinguish between VT and Vfib based on rate. It has two zones a vtach zone and a vfib zone. Depending of the model many icds would try to pace in the vtach zone to supress the VT, whereas it would shock in the vfib zone. A fast vtach would normally be taken as a vfib by the ICD and given a shock, which also seems appropiate |
