An Analysis of Arterial Pulse Wave Time Features and Pulse Wave Velocity Calculations Based on Radial Electrical Bioimpedance Waveforms in Patients Scheduled for Coronary Catheterization.

Based on coronary lesions, we formed four groups of patients: the first group with normal coronaries, the second group with minimal/moderate changes (≤50% stenoses), the third group with moderately significant coronary lesions (51–75% stenoses), non-revascularization objects, and 1–2 vessel disease), and the fourth group with significant (51–100% stenoses) that are objects of revascularization and three-vessel disease ( Figure 4 and Figure 8 a).
