HeartStart MRx
Instructions for Use Clarification
N O T E
This document is an addendum to and should be kept with your HeartStart MRx Instructions for Use.
Default Lead Behavior
The HeartStart MRx allows you to configure the lead displayed as the Primary ECG lead in Wave Sector 1
when the device is turned on. The factory default is Lead II. Refer to Chapter 17 of the HeartStart MRx
Instructions for Use for more information on Configuration.
When you first turn your HeartStart MRx on, it searches for the default Primary ECG lead which was selected
in configuration setup. If the default lead is not available, the device automatically searches for the next available
lead. Once it finds an available lead, it is displayed in Wave Sector 1. If the default Primary ECG lead becomes
available, the HeartStart MRx automatically switches the monitored wave in Wave Sector 1 to that default lead.
If the lead in Wave Sector 1 is lost, a dashed line is displayed. The device does not revert back to another lead,
even if one is available. Press the Lead Select Button multiple times until another available lead is displayed
(see Figure 1).
Synchronized Cardioversion using External Paddles
WARNING
When performing Synchronized Cardioversion using external paddles, you should not use paddles as your
monitoring lead in Wave Sector 1. Artifact introduced by paddle movement may resemble an R-wave and
trigger a defibrillation shock.
Carefully review the waveform prior to administering Synchronized Cardioversion and confirm that you have
a non-paddles Wave Label (see Figure 1).
Steps for performing Synchronized Cardioversion using External Paddles:
1 Prepare your patient for Synchronized Cardioversion according to the HeartStart MRx Instructions for Use
and your institution's protocol
Place paddles on the patient's chest prior to charging the defibrillator

• confirm a non-paddles monitoring lead appears in Wave Sector 1. Then proceed with your institution's
protocol for Synchronized Cardioversion
