Overview
Open Clinical controls → Baseline vitals → Rhythm and choose Atrial Bigeminy. The rate and atrial/ventricular timing follow this rhythm’s model.
Every second P wave is premature and has a different morphology; conducted QRS remains narrow. Early filling is reduced and the reset pause is noncompensatory relative to the underlying sinus cycle.
The disease state remains active. Disease morphology, treatment and temporary pacing can modify the displayed result; use the effective rate and the current twelve-lead read.
