The Physio-Control LIFEPAK 12/15/20 QUIK-COMBO 12-Lead Patient Simulator simulates patient heart rhythms. The device allows users to practice and demonstrate monitoring with the 12-lead or 5-wire ECG cable and defibrillating with the QUIK-COMBO therapy cable. It connects directly to your LIFEPAK defibrillator for safe simulation of cardioversion and electrical capture. This simulator generates fibrillation, tachycardias, and bradycardias, as well as ST segment and T wave abnormalities. It was designed for use with LIFEPAK devices with a 12-lead ECG feature.
