The patient count denotes the number of cases where the given current threshold was sufficient for successful atrial capture.
The results show that successful atrial capture at pulse current 16 mA or less was feasible in more than 80% of patients, and the current of 19 mA would have been sufficient for capture in 100% of patients (Fig.
Bringing Atrial Capture Management into clinical evaluation is another significant milestone in our continued leadership in developing new treatment options for patients with bradycardia.
