Implication
Endocardial unipolar mapping may identify epicardial VT substrate in LVCM; leaves open prospective validation before routine adoption.
Structured PICO
Does endocardial unipolar voltage mapping reliably identify epicardial ventricular tachycardia substrate in patients with nonischemic left ventricular cardiomyopathy?
P
Population
Patients with nonischemic left ventricular cardiomyopathy (LVCM)
I
Intervention
Endocardial unipolar (ENDO UNI) voltage mapping
O
Outcome
Detection of epicardial (EPI) ventricular tachycardia substratesurrogate
Endocardial unipolar voltage mapping can reliably identify epicardial arrhythmia substrate in patients with nonischemic left ventricular cardiomyopathy even without endocardial bipolar abnormalities.
