Abstract: Devices and methods for the treatment of heart conditions, and other medical purposes, include cardiac pacing systems. For example, this document describes temporary transvenous endocardial pacemaker systems and devices for deploying such systems without the need for conventional imaging procedures.

Abstract: Devices and methods can be used for artificial cardiac pacing and/or resynchronization. For example, this document provides improved electrodes for stimulating and sensing electrical activity of the heart, and provides pacing and resynchronization systems incorporating such electrodes. While the devices and methods provided herein are described primarily in the context of pacing, it should be understood that resynchronization can additionally or alternatively be performed in an analogous manner, and that the scope of this disclosure includes such subject matter.

Abstract: Systems, methods, devices, and techniques for analyzing and applying features of a T-wave derived from an electrocardiogram. A computing system can receive a set of data that characterizes an electrocardiogram of a patient. The system can analyze the set of data to identify a T-wave that occurs in the electrocardiogram. The system can determine values of one or more features of the T-wave and provide the information that identifies the values of the one or more features of the T-wave to a user.

Abstract: A physical system receives and records measurements from a plurality of sensors for the physical system over a period of time and creates therefrom a statistical model of normal behavior of the physical system. The statistical model is applied to monitor the physical system for events or significant changes. The method detects events or significant changes in the operation or behavior of the physical system responsive to the monitoring of the physical system for events or significant changes. Events or significant changes in the operation or behavior of the physical system may cause a notification or alert, which can be sent a supervisory system.

Abstract: Systems, methods, and other techniques for estimating the level of an analyte present in a patient during a time interval using electrocardiogram (ECG) signals. The estimate can be improved using information about the patient's posture.

Abstract: Systems and methods for epicardial pacing are provided. For example, this document provides epicardial pacing using a percutaneously delivered bifurcated pacing lead that has multiple electrodes that are directionally insulated to prevent extracardiac stimulation, including prevention of phrenic stimulation. In addition, the devices, systems, and methods provided can be used for ablation, defibrillation, and/or defibrillation in combination with pacing.
