摘要： A method for selecting a target vein for left ventricular lead placement for cardiac resynchronization therapy includes determining electrical dispersion for the first coronary vein by calculating the difference between (i) activation time at a location of the vein that has the latest activation time of a plurality of locations in the vein and (ii) activation time at a location that has the earliest activation time of the plurality of locations. The method may further include (ii) determining whether the magnitude of the electrical dispersion for the vein meets or exceeds a predetermined threshold selecting the vein if the vein meets or exceeds the predetermined threshold; or (ii) selecting, among several veins, the vein that has the highest electrical dispersion.

摘要： A medical device system and associated method for controlling a cardiac rhythm management therapy detect extracardiac stimulation. Cardiac pacing pulses are delivered, and a cardiac electrical signal comprising myocardial depolarization and repolarization signals is acquired. A processor is configured to, responsive to the cardiac electrical signal, detect extracardiac capture due to the cardiac pacing pulse.
