🟠 Short asymptomatic transition from trigeminy to bigeminy

This case highlights a 63-year-old male with a known history of atrial fibrillation (AFib) and heart failure. During a single spot check with FibriCheck, the patient displayed an asymptomatic, non-AFib irregular rhythm characterized by variations in ectopic beat patterns — transitioning between bigeminy and trigeminy within the same 60-second measurement.

The tachogram and Lorenz plot revealed distinct beat-to-beat irregularities while maintaining an average heart rate of 69 bpm. These findings demonstrate how multiple ectopic patterns can occur transiently before the onset of AFib and how PPG-based measurements can capture these short-term rhythm transitions with high precision.

Takeaway:
When irregularities occur, verifying beat detection quality is essential before interpreting the tachogram and Lorenz plot. Once confirmed, FibriCheck enables clear differentiation between varying ectopic patterns within a single short measurement.
