Does endocardial unipolar voltage mapping reliably identify epicardial ventricular tachycardia substrate in patients with nonischemic left ventricular cardiomyopathy?
Endocardial unipolar voltage mapping can reliably identify epicardial arrhythmia substrate in patients with nonischemic left ventricular cardiomyopathy even without endocardial bipolar abnormalities.
EPI arrhythmia substrate can be reliably identified in most patients with LVCM using ENDO UNI voltage mapping in the absence of ENDO BIP abnormalities.
Hutchinson et al. (Sat,) studied this question.
