Recent developments in techniques for cardiac resuscitation and procedures in other cardiac emergencies often make it desirable to obtain an electrocardiogram rapidly and efficiently. In the development of a "crash cart" to expedite resuscitative procedures, a towel clip was modified to permit the rapid attachment of electrocardiographic leads to the patient. A piece of tubular brass is cut to the appropriate length, with an internal luminal diameter which would permit insertion of the lead. The brass tube is welded to the towel clip in the manner shown in Figure 1. Initially it was considered necessary to insulate portions of the handle of the towel clip to decrease electrical interference. In experimental and clinical trials of the technique, however, insulation has not been required.
