Does ventricular tachycardia substrate ablation incorporating hidden slow conduction analysis by double ventricular extrastimuli improve arrhythmic substrate identification and reduce VT inducibility in patients undergoing VT ablation?
Incorporating hidden slow conduction analysis by double ventricular extrastimuli during VT ablation improves substrate identification and reduces RF time and VT inducibility.
Ventricular tachycardia substrate ablation incorporating HSC analysis allowed further arrhythmic substrate identification (especially in normal-voltage areas) and reduced RF time and VT inducibility after VTSA.
