From: Arrhythmogenic substrate at the interventricular septum as a target site for radiofrequency catheter ablation of recurrent ventricular tachycardia in left dominant arrhythmogenic cardiomyopathy

Figure 3

The bipolar voltage map of both ventricles in sinus rhythm. An atypical range (2–4 mV) for color-coding was used to highlight the areas of subtle reduction of bipolar voltages. The cross denotes the left ventricular apicoseptal region of abnormal electrograms where the endomyocardial biopsy was taken. The arrow indicates the site with a maximum stimulus-to-QRS interval at the right-sided interventricular septum. The asterisk shows the site of the pacemap for the clinical tachycardia at the left-sided interventricular septum site with normal electrograms.
