Arrhythm Electrophysiol … WebVentricular tachycardia (VT) originating in the right ventricular outflow tract (RVOT) is the most common form of idiopathic VT. Catheter ablation of right ventricular outflow tract tachycardia (RVOT-VT) is associated with high success rates. However, non- inducibility of VT on electrophysiological (EP) study can severely impact ablation outcome.

Web13 de ago. de 2024 · We enrolled 23 consecutive patients undergoing catheter ablation for atrioventricular reentrant tachycardia. High-density mapping was performed using OWM and ablation was performed. The successful site of ablation was determined by the loss of pathway function. Results
Web5 de nov. de 2024 · Conventional scar and low BV thresholds (0.5–1.5 mV) were defined by Marschlinski et al., based on mapping with a conventional large-tip electrode. 1 The 1.5 mV threshold has been validated in animal models of transmural myocardial infarcts, but the dense scar level of 0.5 mV has been arbitrarily defined. 26 Based on the prior findings … Web9 de jan. de 2024 · Ventricular tachycardia (VT) substrate ablation is based on detailed electroanatomical maps (EAM).

WebHigh-density mapping of 84 ATs was performed in 41 patients (macroreentrant, 47; focal, 37). Of the 84 ATs, 50 were left-sided (60%). The median mapping points were 3119 (IQR, 2315–4977) points, and the median tachycardia cycle length was 261 (IQR, 217–300) ms ( …
Web1 de jan. de 2014 · High-density mapping shows substantial differences among channels in ventricular scar. Channels supporting VT are more commonly located in dense scar, longer than non-VT channels, and have slower conduction velocity. Only a minority of scar-related potentials participate in the VT supporting channels.
