摘要： Provided are a patient monitor and vital-sign data statistics system, having vital-sign data statistics functionality. The patient monitor includes a signal acquisition module, a data processing module, and a display module. The data processing module processes the vital-sign signal acquired by the signal acquisition module and generates physiological parameters. If request information requesting to display a vital-sign data statistics result is received, then the data processing module statistically classifies the vital-sign data within a preset time range according to set type and a statistical item of each type, and displays the data by means of the display module.

摘要： In situations in which an implantable medical device (e.g., a subcutaneous ICD) is co-implanted with a leadless pacing device (LPD), it may be important that the subcutaneous ICD knows when the LPD is delivering pacing, such as anti-tachycardia pacing (ATP). Techniques are described herein for detecting, with the ICD and based on the sensed electrical signal, pacing pulses and adjusting operation to account for the detected pulses, e.g., blanking the sensed electrical signal or modifying a tachyarrhythmia detection algorithm. In one example, the ICD includes a first pace pulse detector configured to obtain a sensed electrical signal and analyze the sensed electrical signal to detect a first type of pulses having a first set of characteristics and a second pace pulse detector configured to obtain the sensed electrical signal and analyze the sensed electrical signal to detect a second type of pulses having a second set of characteristics.

摘要： A system for electrophysiological measurement includes a probe having a distal end configured for insertion into a body cavity of a living subject and including an array of electrodes that are disposed along the distal end and are configured to contact tissue at multiple locations within the body cavity. A processor is configured to acquire signals from the electrodes over a period of time during which the probe moves within the body cavity, to compute, in response the signals, metrics that are indicative of a respective quality of contact between each of the electrodes and the tissue over the period of time, and to output an indication of the metrics to a user of the system.
