Does analysis of electrograms from clinical noncontact mapping during sinus rhythm and VT predict effective ablation sites in patients with VT?
Analysis of electrograms during sinus rhythm or VT using noncontact mapping can predict effective ablation sites without the need for full activation maps.
In selected patients with VT who have a complete endocardial circuit, isthmus location and shape can be discerned by analysis of sinus rhythm or tachycardia electrograms, and an effective ablation site can be predicted without the need to construct activation maps of reentrant circuits.
