Method

• Simultaneous side-by-side time course plot of Mespere’s plethysmographic waveform and ECG waveform
• Conducted by three (3) medical physicians
• Blinded study
• Three (3) healthy volunteers recruited

Results

• All physicians could clearly identify the a, c, and v waves in Mespere’s plethysmographic waveforms
• Physicians confirmed the temporal correlation with ECG waveforms in most occasions
