A temporary cardiac lead for establishing electrical contact between a body tissue and a pulse generator. The lead includes a flexible conductor having a proximal end and a distal end. The proximal end of the conductor is connected to the pulse generator. An electrode is connected to the distal end of the connector for establishing electrical contact with the body tissue. A helical coil is secured to the electrode for frictionally resisting the movement of the lead relative to the body tissue. The coil has a generally rectangular cross-section, for giving it an overall flat configuration, in order to improve the positioning of the coil within the myocardial tissue, to dispense with auxiliary accessories such as silicon rubber discs, and to reduce the size of the lead and to render it adequate for use in atrial and pediatric applications.
