Can Arrhythmia (A-Fib) Affect PWA Accuracy?

Yes. Atrial fibrillation can affect PWA accuracy. The SphygmoCor XCEL is not indicated for patients with erratic, accelerated, or mechanically controlled irregular heart rhythms, including those with arrhythmias.

See the Troubleshooting section for guidance on managing measurements in patients with A-Fib or frequent PVCs.
