This is the Lite/preview version of "CARDIO3® Atlas of Cardiac Electrophysiology & Arrhythmia" – reference/learning tool for cardiologists, internists and other physicians evaluating electrophysiology images and ECG.
Isochronal (A,C) and voltage maps (B,D) in LAO and left lateral view. Local voltage is color-coded (red color = voltage below 1.5 mV) and depicts a large aneurysm of the anterior wall. Gray color represents dense scar without electrical activity and no capture during pacing (at 10mA).
Colors represent voltage amplitudes of local electrograms (red color – low voltage, violet color – healthy tissue). Borderzone of healthy and scar area creates a arrhythmogenic substrate for reentrant ventricular arrhythmias. Dark red points represents the sites of radiofrequency ablation.
