Abstract: A medical device is configured to detect an atrial tachyarrhythmia episode. The device senses a cardiac signal, identifies R-waves in the cardiac signal attendant ventricular depolarizations and determines classification factors from the R-waves identified over a predetermined time period. The device classifies the predetermined time period as one of unclassified, atrial tachyarrhythmia and non-atrial tachyarrhythmia by comparing the determined classification factors to classification criteria. A classification criterion is adjusted from a first classification criterion to a second classification criterion after at least one time period being classified as atrial tachyarrhythmia. An atrial tachyarrhythmia episode is detected by the device in response to at least one subsequent time period being classified as atrial tachyarrhythmia based on the adjusted classification criterion.

Abstract: A medical device performs a method for detecting an atrial tachyarrhythmia by determining RR intervals between successive R-waves of a cardiac electrical signal and determining classification factors from the R-waves identified over a predetermined time period by determining at least a first classification factor correlated to variability of the RR intervals and a second classification factor indicating a presence of a ventricular tachyarrhythmia. The device classifies the cardiac electrical signal of the predetermined time period as unclassified, atrial tachyarrhythmia or non-atrial tachyarrhythmia by comparing the determined classification factors to classification criteria. The predetermined time period is classified as unclassified when the second classification factor indicates the presence of a ventricular tachyarrhythmia.

Abstract: A system for detecting an atrial tachyarrhythmia episode includes a medical device having sensing circuitry configured to receive a cardiac electrical signal from electrodes coupled to the medical device and a processor configured to detect an atrial tachyarrhythmia episode in response to a time duration of the cardiac electrical signal classified as an atrial tachyarrhythmia being greater than or equal to a first detection threshold. The processor is configured to determine if detection threshold adjustment criteria are met based on at least the detected first atrial tachyarrhythmia episode and adjust the first detection threshold to a second detection threshold different than the first detection threshold in response to the detection threshold adjustment criteria being met.

Abstract: A system for sensing physiological traits of a maternal patient and a fetal patient carried by the maternal patient during a pregnancy using one or more sensors. The system may use the physiological traits sensed to define a maternal attribute for the maternal patient and a fetal attribute for the fetal patient, such as a heart rate, blood pressure, respiration rate, temperature, oxygen saturation level, or other attributes. The system is configured to compare the maternal attribute to a maternal limit describing a threshold for the maternal patient and/or compare the fetal attribute to a fetal limit describing a threshold for the fetal patient. The system is configured to issue a communication to the maternal patient and/or a clinician based on the comparisons. In examples, the system regularly communicates the maternal attribute and/or the fetal attribute to an output device of the maternal patient and/or a clinician.

Abstract: A system comprising an implantable medical device and processing circuitry. The implantable medical device comprises one or more sensors configured to continuously sense one or more physiological characteristics of a body of a maternal patient, and sensing circuitry operably connected to the one or more sensors and configured to issue one or more output signals indicative of the one or more physiological characteristics. The processing circuitry is configured to define one or more patient attributes using the one or more output signals; and generate an output based on the one or more patient attributes, the output configured to cause a computing device to provide an indication of preeclampsia of the maternal patient to a user.

Abstract: A system for sensing one or more physiological traits and obstetric conditions, such as a fertility phase, pregnancy, labor, post-partum conditions, and other conditions related to the reproductive system of the patient. The system may use the one or more physiological traits sensed to define one or more patient attributes for the patient, such as a hormone level, heart rate, blood pressure, respiration rate, temperature, oxygen saturation level, uterine contractions, fluid level, and/or other patient attributes. The system is configured to compare the one or more patient attributes to one or more attribute signs describing a threshold for the one or more patient attributes. The system is configured to issue a communication to the patient and/or a clinician based on the comparisons. The system may be configured to assess and indicate reproductive phases for the patient over a life-cycle from the fertility phase to the post-partum phase.
