Does microelectrode mapping with the QDOT MICRO ablation catheter improve electrogram detection and allow safe HPSD ablation in patients with ventricular tachycardia?
The QDOT MICRO ablation catheter with microelectrode mapping improves detection of higher voltage electrograms and allows safe HPSD ablation in low voltage areas for ventricular tachycardia.
Microelectrode mapping allows detection of higher voltage electrograms compared to standard bipolar mapping and PR mapping. In our small population, the HPSD protocol was used inside the low voltage areas without acute procedural complications.
Monaco et al. (Mon,) studied this question.
