Minute Ventilation

Clinical Data

Heart Rate (HR) Score is a simple measurement that can predict survival. It is defined as the height of the tallest atrial histogram bin. Since a broader range of heart rate is typically better for the patient, a lower HR Score is preferred.1

RightRate Was Shown to Improve HR Score More Than an Accelerometer Alone2

In an analysis of more than 500 patients, RightRate Minute Ventilation (XL + MV) was associated with a Heart Rate Score reduction of 18% and converted nearly twice as many patients to a HR Score of up to 70% compared to an accelerator alone.

HR Score Was an Independent Predictor of Mortality1

A LATITUDE™ analysis of almost 68,000 CRT-D patients showed that patients with an HR Score of 70 or greater had a 43% 5-year survival rate, while a HR Score below 30 had a 68% 5-year survival rate across the same period.
