Abstract: The present disclosure provides systems and methods for applying anti-tachycardia pacing (ATP) using subcutaneous implantable cardioverter-defibrillators (SICDs). An SICD implantable in a subject includes a case including a controller, and at least one conductive lead extending from the case. The at least one conductive lead includes a plurality of coil electrodes, wherein the SICD is configured, via the controller, to apply anti-tachycardia pacing (ATP) to the subject using the at least one conductive lead.

Abstract: An implantable medical device includes a header configured to be mounted to an end of a device housing that contains an electronics module therein. The header includes an antenna, a sensing electrode, and a header body that at least partially surrounds the antenna and the sensing electrode. The sensing electrode includes a first body portion, a second body portion, and a bridge portion that mechanically and electrically connects the first and second body portions. The first body portion is at least partially exposed to an external environment along a first side of the header, and the second body portion is at least partially exposed to the external environment along a second side of the header that is different from the first side.

Abstract: Embodiments described herein can reduce a burden associated with analyzing EGM segments obtained from an IMD that monitors for arrhythmic episodes. Respective EGM data and respective classification data is obtained for each arrhythmic episode detected by the IMD during a period of time. A representative R-R interval or HR for each of the arrhythmic episodes is also obtained, wherein a manner for determining the representative R-R interval or HR depends on the type of the arrhythmic episode, such that for at least two different types of arrhythmic episodes the manners differ. One or more arrhythmic episodes is/are selected for which corresponding EGM segments are to be displayed for each type of arrhythmic episode, wherein the selecting is performed based on the representative R-R intervals or HRs that are determined for the plurality of arrhythmic episodes. Additional and alternative embodiments are also described herein.

Abstract: Methods and systems are provided for managing presentation of cardiac activity signals. The methods and systems obtain device classified (DC) data sets generated by an implantable medical device (IMD), the DC data sets including a corresponding cardiac activity (CA) segment from an episode identified by the IMD; compare the CA segments, associated with different episodes, to one another to identify a level of similarity therebetween; separate the CA segments into at least first and second clusters based on the level of similarity; designate a first representative CA segment from the first cluster to be representative of the CA segments in the first cluster; and designate a second representative CA segment from the second cluster to be representative of the CA segments in the second cluster; and a display to present the first and second representative CA segments as representative of the first and second clusters.

Abstract: Optical readers and alignment tools for detecting the level of an analyte. Described herein are small, disposable partially-encapsulated sensing chips for detecting an analyte level from a fluid sample (e.g., a blood sample) having an edge of the integrated sensing chip exposed to directly expose a plurality of excitation and a collection waveguides, as well as optical readers and methods of operating them. A fluid sample maybe applied to a sensing surface of the sensing chip in the housing so that an analyte level can be optically detected. Also described are methods of sensing an analyte using these devices and systems including an optical detector.
