A cardiac pacing lead for pacing the atria and a method of its use. The lead is provided with a mechanism for maintaining an atrial pacing electrode adjacent stimulable tissue in a patient's superior vena cava and an additional electrode locatable in the right ventricle or elsewhere when the atrial electrode is so located. One such mechanism for maintaining the atrial electrode's position may be a lead body displaying pre-formed laterally extending curves sized to span a patient's superior vena cava, with the atrial electrode located thereon. |
