🟠 Bigeminy episode with different coupling intervals

This case describes a 57-year-old male with a known history of atrial fibrillation (AFib). During a FibriCheck spot check, the patient exhibited a bigeminy rhythm with an average heart rate of 69 bpm.

Across the full 60-second recording, the ectopic beats showed variable coupling intervals, alternating between approximately 200 ms and 374 ms. The tachogram and Lorenz plot highlight these shifts in beat timing, confirming that the bigeminal pattern is not only present but also dynamic in its coupling behaviour within a single short measurement.

Takeaway:
FibriCheck PPG can identify bigeminy patterns and their coupling-interval variability, enabling more detailed characterization of ectopic rhythms even during brief spot checks.
