Abstract: A method and system for delivering anti-tachycardia pacing is disclosed. A cardiac rhythm management device, such as an implantable pacemaker having anti-tachycardia pacing capability, delivers anti-tachycardia pacing therapy in accordance with an anti-tachycardia pacing protocol upon detection of a terminable arrhythmia. The anti-tachycardia pacing is delivered as a burst of one or more pacing pulses at a specified coupling interval after a sensed ventricular polarization. By sensing if an evoked potential occurs, the device can determine whether or not the anti-tachycardia pacing burst has captured the ventricle and can adjust the coupling interval and/or other parameters accordingly.

Abstract: A first electrode is positioned within an artery proximate an implanted intravascular stent. A second electrode is positioned at a separate location relative the position of the first electrode. Electrical energy is then delivered between the first and the second electrodes to produce an electrical field adjacent the implanted intravascular stent. When a intravascular stent is implanted in a coronary artery, the delivery of the electrical energy is coordinated to cardiac cycles detected in sensed cardiac signals, where the delivery of the electrical energy between the first electrode and the second electrode occurs during a predetermined portion of the cardiac cycle.
