BIOTRONIK has just announced that its Closed Loop Stimulation (CLS) physiologic sensor is now available on the Itrevia cardiac resynchronization therapy defibrillator (CRT-D) in the United States. The CLS sensor adjusts the patient heart rate in response to physical activity, even when there’s no change in the respiratory rate or body movement.
Typically, CRT-Ds monitor patient movements using a built-in accelerometer, but that can be deceptive depending on the physical activity. The CLS technology uses impedance sensing to compensate for changing mental stress, similar to how the body’s own healthy nervous system coordinates with the heart.
From the announcement:
The latest BIOTRONIK Itrevia ICD and CRT-D series* includes other advanced atrial therapies: morphology discrimination, Vp Suppression®, atrial capture control, improved ATP optimization and LV pacing vectors. Combined, they create more therapeutic options to deliver effective therapy while reducing painful shocks. All devices include BIOTRONIK Home Monitoring®, the first remote monitoring system and the only system with automatic daily transmission, which has been shown to reduce all-cause mortality by over 50 percent3.
“CLS is the only FDA-approved sensor to respond to acute mental stress on a beat-to-beat basis,” said Marlou Janssen, President, BIOTRONIK, Inc. “We are very pleased to make this unique technology available for heart failure patients. CLS is another BIOTRONIK core technology that works to improve the quality of patients’ lives, allowing them to experience a wider range of physiologic responses than with other CRM devices.”
