This chapter explains how to prepare for and perform defibrillation or asynchronous cardioversion on the
HeartStart XL+ using multifunction electrode pads, external paddles and internal paddles.
Chapter 7 "Cardioversion"
Defibrillation therapy is the definitive method for termination of lethal arrhythmias.The HeartStart XL+
provides this therapy through the application of a biphasic pulse of current to the heart. This electrical
energy is transferred through attached paddles or disposable multifunction electrode pads applied to the
patient's bare chest. Internal paddles for open-chest intrathorasic defibrillation can also be used.
In Manual Defibrillation Mode, the entire defibrillation process is under your control. You must assess
the ECG, decide if defibrillation or cardioversion is indicated, select the appropriate energy, charge the
HeartStart XL+ and deliver the shock. Text messages on the display provide relevant information
throughout the process. Be attentive to these messages when displayed.
The ECG strip and Event Summary are easily annotated with information using the Mark Event button.
Monitoring alarms are available in Manual Defibrillation Mode but they are turned off by default.
To activate alarms, press the Alarm button
The HeartStart XL+ Manual Defibrillation Mode can be used on both adult and infant/child patients.
