About this study

The primary objective of this pilot study is to document the percentage achievement in effective HR control (average nighttime HR \< 70 bpm) during WCD use in a cohort of female patients with cardiomyopathy in an outpatient setting using continuous heart rate (HR) trends data from the WCD to optimize BB/ivabradine dosage, as compared to a prior historical control.
