🟠 A tachycardia episode turning into a bigeminy episode

This case describes an 80-year-old male with a medical history of hypertension. During a single spot check with FibriCheck, the recording initially displayed a regular rhythm for the first 20 seconds, followed by a sudden onset of tachycardia lasting approximately 8 seconds. The rhythm then converted into a bigeminy pattern, revealing a clear sequence of rhythm transitions within one short measurement.

Importantly, the patient did not report any symptoms, despite these distinct arrhythmic events — underscoring the value of objective rhythm insights in asymptomatic individuals.

The tachogram and Lorenz plot visualize the dynamic shift from regular rhythm → tachycardia → bigeminy, highlighting how PPG-based analysis can capture and differentiate short-lived arrhythmic behaviour.

Takeaway:
FibriCheck enables the detection and characterization of rapid rhythm transitions within a single measurement — from tachycardia onset to ectopic bigeminy — even when the patient is asymptomatic.
