摘要： An atrial event and a ventricular event can be received, and an atrioventricular (AV) delay can be provided using information about the atrial and ventricular events. The AV delay can be increased after a first condition is satisfied to allow a heart to regain intrinsic control of ventricular activation, and changed after a second condition is satisfied to allow the heart to remain in intrinsic control of ventricular activation.

摘要： Techniques are provided for use with an implantable medical device for detecting breaches in lead insulation or other lead failures. In one example, bipolar impedance is measured along single-lead vectors (i.e. intra-lead vectors) of a right atrial (RA) lead and a right ventricular (RV) leads. Impedance is also measured along various cross-lead vectors (i.e. inter-lead vectors) between electrodes of the two leads. A derived impedance value is then determined from a combination of the measured impedance values, wherein the derived impedance is sensitive to a shunt impedance arising from a breach within the RV lead. A lead breach is then detected relatively early based on the derived impedance by detecting a significant deviation in derived impedance over time. Unipolar impedance measurements are used to confirm the breach.

摘要： A wearable defibrillation system can establish a local comlink with a mobile communication device, such as a smartphone, tablet-type computer and the like. The mobile communication device can in turn establish a remote comlink with other devices in a network such as the internet. Accordingly, communication tasks relating to the wearable defibrillation system can be performed via the local and the remote comlinks, with or without the participation of the patient, who is wearing the system. The wearer can thus use the familiar interface of a mobile communication device for interacting with his defibrillator system. Moreover, he can do so while keeping on his regular clothes, which could conceal completely the wearable defibrillator system. The patient can thus preserve his dignity and privacy.
