1 © 2012 by Boston Scientific Corporation or its affiliates. All rights reserved. CRM-59709-AA AV Synchrony Restored RYTHMIQ operates in AAI(R) pacing mode with VVI backup during times of normal conduction, switching to DDD(R) mode when a conduction block is detected Loss of AV Synchrony Operation RYTHMIQ™

2 © 2012 by Boston Scientific Corporation or its affiliates. All rights reserved. CRM-59709-AA The device provides AAI(R) at the LRL and/or sensor indicated rate with backup VVI pacing at a rate of 15 bpm slower than the LRL When there is good conduction, ventricular pacing does not occur as the VVI backup mode runs in the background During normal conduction, RYTHMIQ operates like two pacemakers running concurrently – one in AAI(R) mode and one in VVI mode. Normal Conduction Operation RYTHMIQ™

CRM-59709-AA The device monitors for loss of AV synchrony to determine when to switch to DDD(R) mode Loss of AV Synchrony If 3 slow ventricular beats are detected in a window of 11 beats, then the device automatically switches to DDD(R) mode. A slow beat for RYTHMIQ is defined as a ventricular pace or ventricular sensed event that is at least 150 ms slower than the AAI(R) pacing rate. Loss of AV Synchrony Operation RYTHMIQ™

CRM-59709-AA #1 #2 #3 INGENIO™ records a RYTHMIQ Episode along with 20 seconds of electrogram data when RYTHMIQ detects loss of AV synchrony. This can help the clinician to diagnose patient rhythm conduction disorders and determine appropriate algorithms and pacemaker settings Operation RYTHMIQ™

CRM-59709-AA If AV Search+ remains in AV hysteresis for at least 25 cardiac cycles, and less than 2 of the last 10 cycles are ventricular paced, then the device automatically switches the pacing mode back to AAI (R) with VVI backup. The device uses AV Search+ to periodically check for a return of intrinsic conduction and determine when to mode switch back to AAI(R) with VVI backup. Normal Conduction Restored AV Synchrony Restored Operation RYTHMIQ™

CRM-59709-AA AV Synchrony Restored RYTHMIQ is designed to adapt to a patient’s conduction disorder, by mode switching when AV synchrony is lost or restored, without clinically significant pauses Operation RYTHMIQ™ Loss of AV Synchrony

CRM-59709-AA RYTHMIQ is designed to minimize unnecessary pacing without clinically significant pauses RYTHMIQ operates like two pacemakers running concurrently— one in AAI(R) and one in VVI RYTHMIQ does not require dropped ventricular beats to switch to DDD(R) pacing Reference Guide, INGENIO Pacemaker, Page 2-53, 358577-001 EN US 11/10 Operation RYTHMIQ™

RYTHMIQ adds another RV pacing algorithm to Boston Scientific devices, because no one algorithm is appropriate for every patient. AV Search+ is designed to reduce unnecessary RV pacing by providing backup ventricular pacing for every beat while searching for intrinsic activity Managing RV Pacing – Two Algorithms RYTHMIQ™ BSC also offers AV Search+

While not an algorithm, an equivalent setting would be available in competitor devices With both RYTHMIQ™ & AV Search+, clinicians now have options to appropriately manage RV pacing in patients with varying degrees of conduction block INGENIO™ pacemakers have two algorithms to help minimize unnecessary RV pacing Managing RV Pacing – Two Algorithms RYTHMIQ™
