AF risk management

Helping you manage what can't be seen

Ventricular Pacing reduction: Protect patients from developing AF2,3,4

Atrial prematurity detection: Detect AF with 96% sensitivity and 96% specificity5

Sleep Apnea screening: Reveal the silent cause of AF6,7

Control AF recurrence risk: Long-term sleep apnea monitoring helps prevent resurgence of AF 8,9,10

ENO CRM Helpingyoumanage 1 1


Physio-inspired design

Mimics the natural way the heart works and minimizes artificial intervention.

Wave to wave thinking

Permanent adaptive strategy for real time decisions that respond to all levels of patient activity, day and night, evolving and learning with the patient.

Symbiotic programming

Programming is driven only by hemodynamic needs. All therapeutic features are independently programmable, designed to work simultaneously together with no conflict.
