Electrophysiology Insights

 
HeartLogic uses automated intelligence to streamline your ability to see each patient’s physiologic response to arrhythmic and pacing changes.

Relationship Between Atrial Fibrillation and HeartLogic Index2

Chart showing the change in the HeartLogic index in comparison to the days from AF progression.

HeartLogic May Detect Sub-Optimal BiV Pacing and Poor Physiologic Response3

Two arrows showing that as the BiV pacing percentage decreased, the HeartLogic index increased.

HeartLogic May Identify Patients Vulnerable to RV Pacing 4
 

Infographic showing that when RV pacing is greater than 10%, the HeartLogic index increases significantly.

MANAGE-HF Study5

 
Phase I of the MANAGE-HF study enrolled 200 patients implanted with a CRT-D or ICD enabled with HeartLogic. The study found that HeartLogic was safely integrated into clinical practice and associated with lower natriuretic peptide levels and hospitalization rates.6

MultiSENSE Study Results7

 
The MultiSENSE study assessed more than 900 patients and validated that the HeartLogic algorithm provides a sensitive and timely predictor of impending heart failure decompensation.

Real-World Evidence

 
In real-world analyses of nearly 500 patients across four studies, HeartLogic was shown to provide consistent heart failure detection performance with low unexplained alert rates.

*The HeartLogic Index and Alert were validated using data from the MultiSENSE study; however, HeartLogic’s impact on clinical outcome has not been established. Establishment of the impact will require a post market trial designed specifically to study clinical outcomes directly related to the use of this feature.
