Abbildung 1A-B: Catheter Ablation
Electroanatomical bipolar voltage map of a left ventricle, the coronary sinus (CS) and the middle cardiac vein (MCV) of a patient with nonischemic dilated cardiomyopathy and ventricular tachycardia (VT) is shown in a caudal left posterior oblique projection. Bipolar voltage of < 0.5 mV (suggestive of a dense scar) is depicted in red and the normal myocardium (with bipolar voltage > 1.5 mV) is represented in purple, with other colors corresponding to the intermediate signal amplitude seen in the scar’s border zone. (A) shows a 12-lead of VT 1 and (B) shows a 12-lead ECG of an VT 2 and corresponding pace map, pointed out from origin with white arrows. Dark blue dots indicate phrenicus capture, light blue dots indicate termination of VT during ablation. Red dots indicate ablation points.
