What is Atrial Fibrillation and how does it affect ICG technology?
Atrial fibrillation is when the normal rhythmical contractions of the cardiac atria are replaced by rapid irregular twitching of the muscular wall, which causes the ventricles to respond irregularly to the dysrhythmic bombardment from the atria1 . 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.

Consequently, depending on the degree of A-fib and the specific patient, the ICG technology system may or may not accept an ICG beat as being vali
