Ba.kground-Endoca.dia. ma.ping before susta.ned monom-orphic ventricula. ta.hyca.dia.SMVT) induction ma. reduce ma.ping time during ta.hyca.dia.a.d fa.ilita.e the a.la.ion of unma.pa.le VT. Methods a.d Results-Left ventricula. electroa.a.omic volta.e ma.s obta.ned during right ventricula. a.ex pa.ing in 26 pa.ients with chronic myoca.dia. infa.ction referred for VT a.la.ion were a.a.yzed to identify conducting cha.nels(CCs) inside the sca. tissue. a.CC wa. defined by the presence of a.corridor of consecutive electrogra.s differentia.ed by higher volta.e a.plitude tha. the surrounding a.ea. The effect of different levels of volta.e sca. definition, from 0.5 to 0.1mV,wa. a.a.yzed. Twenty-three cha.nelswere identified in 20 pa.ients. The ma.ority of CCs were identified when the volta.e sca. definition wa. ≤0.2 mV. Electrogra.s with ≥2 components were recorded more frequently a. the inner tha. a. the entra.ce of CCs(100%versus 75%, P≤0.01). The a.tiva.ion time of the la.est component wa. longer a. the inner tha. a. the entra.ce of CCs(200±40 versus 164±53 ms, P≤0.001). Pa.ing from these CCs ga.e rise to a.long-stimulus QRS interva. (110±49 ms). Ra.iofrequency lesion a.plied to CCs suppressed the inducibility in 88%of CC-rela.ed ta.hyca.dia.. During a.follow-up of 17±11 months, 23%of the pa.ients experienced a.VT recurrence. Conclusions-CCs represent a.ea. of slow conduction tha. ca. be identified in 75%of pa.ients with SMVT. a.tie red decrea.ing-volta.e definition of the sca. is critica. for CC identifica.ion.

In spite of the current preva.ence of the CVD-ba.ed processes, the electric a.c rema.ns a. interesting process for the synthesis of ca.bon na.oforms, tha.ks to its versa.ility, robustness a.d ea.iness. It a.so a.lows performing in-situ substitution of ca.bon a.oms by hetero-elements in the gra.hene la.tice. Our work a.ms to esta.lish a.correla.ion between the pla.ma.properties, type a.d chemica. composition （a.d the substitution ra.e） of the obta.ned single-wa.l ca.bon na.- otubes. The pla.ma.wa. cha.a.terized by optica. emission spectroscopy a.d the products were a.a.yzed by high resolution tra.smission electron microscopy a.d core level Electron Energy-Loss Spectroscopy （EELS）. Results show tha. a.high boron content lea.s to a.pla.ma.tempera.ure decrea.e a.d hinders the forma.ion of na.otubes. This effect ca. be compensa.ed by increa.ing the a.c current a.d/or yttrium content. The optima. conditions for the synthesis of boron- a.d/or nitrogen-substituted na.otubes correspond to a.high a.ia. pla.ma.tempera.ure a.socia.ed to a.strong ra.ia. gra.ient. EELS a.a.ysis confirmed tha. the boron incorpora.es into the gra.henic la.tice.
