The purpose of this study is to validate the Philips DXL electrocardiogram Algorithm works as intended in the HeartStart Intrepid Monitor/Defibrillator after a software update was completed to address instances of high impedance. This study will also determine the diagnostic quality of the 12-lead electrocardiogram tracing from the HeartStart Intrepid Monitor/Defibrillator.
The purpose of this research study is to collect clinical data to validate a software update for 12-lead electrocardiogram monitoring.
