How does Atrial Fibrillation affect ICG technology?
ICG technology looks at the relationship between the mechanical activity (the ICG waveform) and the electrical activity (the ECG waveform) in order to determine the stroke volume on a beat-by-beat basis. For an ICG beat to be determined valid, certain proprietary acceptance criteria are applied. A-fib is a condition that often causes irregular beat-to-beat electrical and mechanical activity. As such, erratic ventricular filling may or may not occur and thus the ECG and ICG waveforms vary widely from beat-to-beat as well as from patient-to-patient.
