title: Crosstalk triggered safety standby pacing associated with an improperly seated ventricular lead.
abstract: Ventricular Safety Standby (VSS) was designed to prevent the potentially serious consequences of crosstalk in many dual-chamber pulse generators. In this report, we describe a patient in whom the VSS was activated in a special way. When the VSS presents during bipolar sensing configuration, the clinician should notice the proper electrical contact between leads and pulse generator.
