| 摘要 |
<p>This invention is a coronary sinus lead (20) for use in combination with an implanted pulse generator (28) which may be a pacemaker or defibrillator or combination thereof. The coronary sinus lead can deliver an electrical charge to pace, cardiovert or defibrillate the heart, and can sense cardiac activity in the coronary sinus of the heart. The coronary sinus lead may include additional sensor electrodes capable of sensing electrical or physical activity in the atrial cavity. The coronary sinus lead allows cardioversion and/or defibrillation stimuli to be provided by a large surface area electrode (162), which is passively implanted in the coronary sinus, to allow the pulse generator to provide appropriately synchronized atrial ventricular pacing, cardioversion or defibrillation.</p> |
