Frequent Hemodynamic CRT optimization with SonR
SonR technology is the only CRT System to provide heart failure patients with automatic and frequent hemodynamic CRT optimization both at rest and exercise. SonR provides a 23% improvement in CRT response1
SonR uses a unique hemodynamic sensor
The unique sensor embedded in the tip of the SonRtip atrial sensing/pacing lead detects cardiac muscle vibrations that correlate to left ventricular (LV) dP/dtmax 2-4 .
Changes in contractility are immediately reflected by the SonR amplitude.
Fewer inappropriate shocks with PARAD+
PARAD+ analyzes arrhythmias as an electrophysiologist would.
Protects patients with best-in-class 99% SVT specificity5
- Only 2.6% of patients received inappropriate shocks at 1 year with PARAD+ out of the box settings6
A full suite of antishock features
The longest experience on dual chamber arrhythmia discrimination
Efficient Resynchronization for active patients with BTO (Brady-Tachy Overlap)
BTO ensures pacing at exercise rate while allowing unmatched accuracy for slow VT discrimination7.8
- Allows patients to be paced in the slow VT zone to favor exercise. Exercise training is part of the treatment of HF patients, reducing mortality and improving QoL9,10
