What is the difference between V pacing, A-sensed/V-paced, A-paced/V-paced and CRT?

The rhythm menu distinguishes atrial timing, ventricular capture and resynchronization examples.

Overview

Ventricular pacing models ventricular activation without atrial tracking. A-sensed/V-paced follows sensed atrial activity with ventricular stimulation. A-paced/V-paced includes separate atrial and ventricular stimuli and capture.

CRT is a representative biventricular pacing pattern. Pacemaker-mediated tachycardia is a different rhythm with a modeled tracking loop. Their pressure consequences follow their timing and hemodynamic rules.

Temporary pacing in Electricity is an intervention applied to the underlying rhythm; selecting a paced rhythm in Baseline vitals instead sets the starting rhythm. The echo schematic displays a pacing lead when pacing is selected.
