{PG,1 An atrial lead assembly is provided which is adapted for curving into position within the atrium, the lead having a flexible length without any preset curve, and comprising stylet means for introducing a curve into the distal end of the lead. The stylet enables the operator to set the axis of the lead along a curvilinear path adjustable by the operator. The lead has a tip of a continuous helical type adapted to be rotated into contact with the trabeculae, the lead being rotatable about the stylet while the stylet maintains the lead axis in a desired position, whereby the tip is caused to engage the trabeculae. After such engagement, the stylet can be removed, leaving the lead tip in good fixation with the atrial wall.
