Sequential synchronized atrioventricular (AV) pacing provides enhanced electrophysiologic parameters which contribute to improved hemodynamic parameters and increased cardiac performance to subsequently confer a clinical advantage over traditional ventricular pacing. Current temporary transvenous pacemaker catheters are limited to only one electrode which paces solely the right ventricle, thus lacking the capability to provide the optimal pacing mode. A new multilead pacemaker device was developed in response to the need for improved temporary pacing through the utilization of sequential synchronized atrioventricular pacing (TAVSP). It consists of seven preformed, preshaped nitinol wires electrodes, of which four are for intra‐atrial and three for intraventricular positioning and endocardial contact, respectively. Each wire carries a ball tip designed to minimize tissue trauma and provide a high current density for adequate myocardial capture. The device is not yet Food and Drug Administration approved.
