🟠 Short bursts of symptomatic bigeminy

This case highlights a 62-year-old male with a known history of atrial fibrillation (AF). During routine spot checks with FibriCheck, the patient showed an overall regular rhythm interspersed with short-lasting, symptomatic episodes of bigeminy.

The tachogram and Lorenz plot clearly visualize alternating normal and ectopic beats, characterized by consistent coupling intervals followed by compensatory pauses — confirming a bigeminal pattern. The correlation with the patient’s symptom report further reinforces the clinical relevance of these short-lived ectopic events.

Takeaway:
Even brief or intermittent ectopic beat patterns can be accurately identified on PPG. The presence of stable coupling intervals and compensatory pauses enables precise recognition and differentiation of bigeminy using FibriCheck.
