The conventional clinical procedure in an electrophysiological study (EPS) involves transvenous catheterisation and access to x-ray fluoroscopy. Esothoracic electrophysiology (ETE) is a viable noninvasive alternative for conducting EPS without access to fluoroscopy and consequently, with more relaxed clinical environmental restrictions. This paper describes the first esothoracic pacing system capable of producing the Wellens test for VT inducibility with a high degree of success. Results as presented for 12 patients comparing catheterisation and ETE show 6 patients being inducible, 4 not inducible, one false positive and one false negative.
