摘要： This disclosure is directed to devices, systems, and techniques for estimating a serum potassium level. An example system includes a plurality of electrodes, sensing circuitry configured to sense an ECG of a patient, and processing circuitry. The processing circuitry is configured to determine a T-wave morphology in the ECG and based on the T-wave morphology, determine an estimate of serum potassium in blood of the patient. The processing circuitry is configured to determine that the estimate of serum potassium in the blood satisfies a threshold and based on the estimate of serum potassium in the blood satisfying the threshold, generate an indication for output that is based at least in part on the estimate of serum potassium in the blood satisfying the threshold.

摘要： This disclosure is directed to systems and techniques configured to apply at least one criterion to health event data stored in a record for a patient for determining whether to remove at least a portion of the health event data from the record or retain that portion as an accurate reflection of patient health for that point- in-time. The health event data includes adjudicated health events and non-adjudicated health events over a first time period. Based on a determination that the health event data satisfies the at least one criterion, the example technique may direct the example system to remove the health event data corresponding to the adjudicated health events and the non-adjudicated health events from the record and then, adjust longitudinal diagnostic information of a second time period that includes the first time period.

摘要： This disclosure is directed to devices, systems, and techniques for delivering electrical stimulation. In some examples, a system includes processing circuitry configured to: receive information representative of a bioelectric brain signal recorded from a brain of a patient; and determine, based on the information, at least one pathological frequency of the bioelectric brain signal. Additionally, the processing circuitry is configured to select, based on the at least one pathological frequency, a sequence of pulse bursts at a pulse burst frequency, the sequence of pulse bursts at least partially defining electrical stimulation deliverable to an area of a brain of a patient, wherein adjacent pulse bursts within the sequence comprise different intra-burst pulse frequencies; and control a medical device to deliver the electrical stimulation comprising the sequence of pulse bursts to the area of the brain of the patient.

摘要： A medical device is configured to receive cardiac electrical signals and sense ventricular event signals from the cardiac electrical signals. The medical device may start a validation window in response to sensing a ventricular event signal and determine if the ventricular event signal is a valid event signal or an invalid event signal based on processing of a different cardiac electrical signal than the cardiac electrical signal from which the ventricular event signal was sensed.

摘要： Transcatheter prosthesis delivery catheter assemblies having a catheter and a lumen extending through the catheter. Such assemblies also have a elongate body having an outer surface and extending at least partially within the lumen. The elongate body has a stop. Delivery catheter assemblies also include a capsule interconnected to the catheter with the elongate body, the capsule including a reservoir. A fluid path extends from the lumen to the reservoir, within the capsule. A prosthesis is loaded within the capsule. Methods can include delivering the capsule though a patient's vasculature to a treatment site and directing fluid in a direction from the lumen, over the elongate body and into the reservoir to cause the capsule to advance with respect to the catheter, at least partially unsheathing the prosthesis, until the stop restricts further movement of the capsule and prevents further fluid from being transferred from the lumen to the reservoir.

摘要： Devices, systems, and techniques are disclosed for planning, updating, and delivering electric field therapy. In one example, a system comprises processing circuitry configured to receive a request to deliver alternating electric field (AEF) therapy and determine therapy parameter values that define the AEF therapy, wherein the AEF therapy comprises delivery of a first electric field and a second electric field. The processing circuitry may also be configured to control an implantable medical device to deliver the first electric field from a first electrode combination of implanted electrodes and control the implantable medical device to deliver, alternating with the first electric field, the second electric field from a second electrode combination of implanted electrodes different than the first electrode combination.

摘要： This disclosure describes systems, devices and techniques for improving the longevity of battery life in a second device. An example first device includes communication circuitry configured to communicate with the second device and one or more sensors configured to sense parameters associated with the first device. The first device includes processing circuitry configured to determine a first time period when a likelihood of successful communications with the second device is higher than a second time period based on the sensed parameters, and control the communication circuitry to communicate with the second device during the first time period and refrain from communicating with the second device during the second time period.

摘要： A system for accounting for adverse pacing artifacts may include an electrode apparatus and a computing apparatus. The electrode apparatus may include one or more external electrodes to monitor electrical activity from tissue of a patient. The computing apparatus may include one or more processors and may be operatively coupled to the electrode apparatus. The computing apparatus may be configured to monitor electrical activity from the tissue of the patient using the one or more external electrodes. Such electrical activity may be used to generate one or more cardiac signals of the patient over time. The computing apparatus may detect a pacing artifact in the one or more cardiac signals and determine whether to account for, and account for, the pacing artifact based on a pacing artifact characteristic of the pacing artifact when producing electrical heterogeneity information.
