A special feature in certain Pacesetter dual-chamber pacemakers which provides a crosstalk sensing window, a short interval following the ventricular blanking period, during which a sensed event will force a ventricular output 120 ms after the preceding atrial output. See also safety pacing. See maximum tracking rate. Return to top of page volt . The force with which electrical current is driven.
Pulse amplitude is stated in volts.
Abbreviated V. VOO . The NBG code for ventricular asynchronous pacing. The NBG code for ventricular asynchronous pacing with rate modulation. The NBG code for ventricular inhibited pacing. The NBG code for a VVI pacemaker with extensive programmability and bi-directional telemetry with both antitachycardia pacing and defibrillation capabilities for the management of ventricular tachycardia.
