Confirm Rx

Insertable Cardiac Monitor with SharpSense Technology

Experience Advanced Detection Accuracy

Capture arrhythmia episodes correctly by significantly reducing false detections.

SharpSense™ technology harnesses the power of extra discriminators to confirm or reject detections - improving accuracy.1,2

Improve detection specificity with SharpSense technology

SharpSense technology is designed with more discriminators, improving specificity while maintaining a high relative sensitivity, to give you actionable information you can use to confidently diagnose bradycardia, pause and AF.1

Confirm Rx ICM Is the Only ICM Available with an AF Indication.

SharpSense™ Technology has led to a 97% Reduction in False Detection of Events2*


Atrial Fibrillation

Actively reviews the previous 30 seconds for the presence of P-waves to discern an AF episode.

Relative Sensitivity: 97.2%1



Dynamically evaluates multiple R-waves and P-waves to create customized thresholds to detect true bradycardia episodes.

Relative Sensitivity: 98.6%1


Analyzes P-wave and R-wave characteristics during the previous 6 seconds, based on customized secondary thresholds, to detect true pause episodes.

Relative Sensitivity: 98.1%1

Kaplan-Meier analysis showed that the Confirm Rx device detected significantly more true arrhythmic episodes in more patients - and did so sooner.3

Diagnose difficult-to-detect arrhythmias

The Confirm Rx ICM device continuously monitors patient rhythm for up to 2 years (730 days).6

84 Days

Median time to detect an AF episode in patients with Cryptogenic Stroke when using an implantable loop recorder.4†

134 Days

Median time for diagnosis in patients with Unexplained Syncope when using an implantable loop recorder.5

730 Days

Confirm Rx ICM offers up to 730 days of continuous heart monitoring — providing ample time to diagnose the most difficult-to-detect arrhythmias.6
