Magnetic versus manual catheter navigation for mapping and ablation of right ventricular outflow tract ventricular arrhythmias: A randomized controlled study
2013, Heart RhythmCitation Excerpt :Pacing was performed at twice diastolic threshold at a cycle length equal to the coupling interval of VPC or cycle length of clinical VT. Pace-maps were scored (maximum score of 24; a score of 1 was acquired for the morphology and amplitude of the QRS complex in each lead if it matched the clinical VPC) by 4 experienced physicians who were blinded to this study.16 Ablation was initiated at either the EA or BO sites of RVOT VA origin identified by the NCM if the following criteria were met: local activation was at least 10 ms pre-QRS, 11 of 12 ECG match during pace-mapping, and virtual unipolar electrograms with QS morphology.
Noncontact mapping to guide ablation of right ventricular outflow tract tachycardia
2002, Journal of the American College of CardiologyCitation Excerpt :Pace mapping may be limited by anodal capture, by capture of a large region of myocardium or by similar appearing pace maps obtainable with stimulation from a relatively large region of myocardium. The resolution of pace mapping is approximately 5 mm to 10 mm, even with the use of strict criteria (10). This may be a limiting factor because typical RF lesions are 5 mm in diameter (11).
