Abstract
A cardiac pacing lead and a method of its use. The lead has an elongated insulative lead body having a distal section formed into a curved configuration appropriate for use in a coronary sinus/cardiac vein of a patient's heart. An active fixation device is located proximal to the distal, curved section of the lead body, which carries an electrode, located along the distal portion of the lead body, spaced from the active fixation device a distance appropriate to locate the electrode adjacent the left atrium or left ventricle of a human heart when the fixation device is located adjacent the ostium of the coronary sinus. The lead is used by advancing the distal portion of the lead through the coronary ostium of the patient's heart and into the coronary sinus/cardiac vein and therefter employing the active fixation device to affix the lead to the patients heart outside of the coronary sinus/cardiac vein.
