Ventricular Fibrillation

Chaotic electrical activity without identifiable QRS complexes or an organized pulse. Pressure traces show a schematic late-arrest baseline of 10 mmHg, not a measured patient value or an onset transition.

Overview

Open Clinical controls → Baseline vitals → Rhythm and choose Ventricular Fibrillation. The rate and atrial/ventricular timing follow this rhythm’s model.

Chaotic electrical activity without identifiable QRS complexes or an organized pulse. Pressure traces show a schematic late-arrest baseline of 10 mmHg, not a measured patient value or an onset transition.

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.

Step by step

  1. Select the rhythm, then adjust Ventricular rate if required.
  2. Compare Lead II, V1 and the arterial pulse.
  3. Open 12-lead ECG; use Variant or Next variant, then Pause → Interpretation.
