Reason for Recall

Issue with ECG out cables. When a Philips monitor/defibrillator is receiving an ECG signal from an auxiliary bedside monitor via a sync cable or ECG out cable, the following can occur if the monitor/defibrillator experiences interference from electrical fast transients (EFTs): " On the HeartStart MRx and HeartStart XL, EFT noise may be misinterpreted as an R-wave. " On the HeartStart XL+, EFT noise can disable ECG monitoring and potentially interrupt demand mode pacing*. *Note: It is contrary to the XL+ Instructions for Use to perform demand mode pacing while using the ECG out cable or obtaining the ECG signal from a bedside monitor. The XL+ Instructions for Use includes the following warning: When pacing in Demand Mode, the ECG cable from the patient must be directly connected to the HeartStart XL+. If the user follows this warning, this problem cannot occur on the XL+.
