  • Patent number: 10617320
    Abstract: An apparatus includes a sensing circuit configured to generate a sensed physiological signal representative of cardiac activity of a subject, an arrhythmia detection circuit, a control circuit, and a memory. The arrhythmia detection circuit detects an episode of atrial fibrillation (AF) in the sensed cardiac signal using a first AF detection criterion, and detects the episode of AF using a second AF detection criterion. The first AF detection criterion has greater sensitivity to AF detection than the second AF detection criterion, and the second AF detection criterion has greater specificity to AF detection than the first AF detection criterion. The control circuit initiates storing of sampled values of a segment of the cardiac signal that includes the episode of AF when the episode of AF is detected by both the first AF detection criterion and the second AF detection criterion.

The sleeve has an internal surface in sliding engagement with the outermost surface of the lead, and an external surface, in which suture grooves are formed. A longitudinal center-to-center spacing between adjacent suture grooves may be substantially the same as, or a multiple of, the longitudinal center-to-center spacing between adjacent depressions of the outermost surface of the lead. The sleeve may also include a ridge protruding from the internal surface, aligned with, or offset (by center-to-center spacing of depressions) from, the grooves.
