Exclusive Algorithms to Manage AF
DETECT
Single Chamber
- TruAF™ Detection Algorithm can detect AF in single
chamber ICD patients using a traditional lead.
Dual Chamber and CRT-D
- Highest published detection accuracy 95-96% episode PPV.§||7-10
AF Episode Detection Accuracy (PPV)<sup>§||10</sup>
REDUCE
Dual Chamber and CRT-D
- Reactive ATP™ opportunistically attempts to terminate an AF episode when the rhythm organises and/or slows.
- 36% relative reduction in AT/AF episodes ≥ 7 days with Reactive ATP Algorithm¶13
- AdaptivCRT™ Algorithm adapts to patients’ changing needs by optimising CRT pacing minute-to-minute.
- 46% reduction in AF risk with AdaptivCRT Algorithm#14

STREAMLINED WORKFLOWS & HEART FAILURE MANAGEMENT
TriageHF™ in Cobalt CRT-D is a simplified, integrated heart failure risk assessment tool that alerts clinicians to clinically relevant changes in a patient’s status that may lead to a heart failure decompensation.
Patient’s risk level is
generated by assessing15:
- OptiVol™
- Patient Activity
- AT/AF Burden
- Ventricular Rate during AT/AF
- % Ventricular Pacing
- Shocks
- Treated VT/VF
- Night Ventricular Rate
- Heart Rate Variability

Energy stored at charge end on capacitor.
§
A controlled, head-to-head study evaluating the comparative performance of device algorithms has not been done. AF detection accuracy rates determined from independent clinical trials are presented for reference.
||
Detection accuracy is compared using PPV, which is the percentage of all AT/AF episodes detected by the individual device detection algorithm that were adjudicated as true AT/AF.
¶
Compared to matched control group.
#
Most of the reduction in AF occurred in subgroups with prolonged AV conduction at baseline and with significant left atrial reverse remodeling.
