Abstract: An example system has a pulse generator configured to deliver a first series of electrical signals to a right atrium of a heart. The first series of electrical signals can increase a first heart rate toward a target heart rate. The system can have a monitoring device configured to retrieve physiological data from a user of the system while the heart is receiving the first series of electrical signals. The system can have a controller configured to determine whether a physiological parameter has met a physiological threshold based on the physiological data. If the physiological threshold has been met, the controller can modify the first series of electrical signals to a second series of electrical signals that restores the physiological parameter to an acceptable level.

Abstract: A medical device, such as an extra-cardiovascular implantable cardioverter defibrillator (ICD), senses R-waves from a first cardiac electrical signal by a first sensing channel and stores a time segment of a second cardiac electrical signal acquired by a second sensing channel in response to each sensed R-wave. The ICD determines morphology match scores from the stored time segments of the second cardiac electrical signal and, based on the morphology match scores, withholds detection of a tachyarrhythmia episode. In some examples, the ICD detects T-wave oversensing based on the morphology match scores and withholds detection of a tachyarrhythmia episode in response to detecting the T-wave oversensing.

Abstract: An ophthalmic surgical laser system and method for forming a lenticule in a subject's eye using “fast-scan-slow-sweep” scanning scheme. A high frequency scanner forms a fast scan line, which is placed by the XY and Z scanners at a location tangential to a parallel of latitude of the surface of the lenticule. The XY and Z scanners then move the scan line in a slow sweep trajectory along a meridian of longitude of the surface of the lenticule in one sweep. Multiple sweeps are performed along different meridians to form the entire lenticule surface, and a prism is used to change the orientation of the scan line of the high frequency scanner between successive sweeps. In each sweep, the sweeping speed along the meridian is variable, being the slowest at the edge of the lenticule and the fastest near the apex.
