Color-coded three-dimensional entrainment mapping for analysis and treatment of atrial macroreentrant tachycardia

Mapping and ablation of atrial macroreentrant tachycardia focus on activation mapping with identification of the area of slow conduction.The purpose of this study was to evaluate a new concept for analysis and treatment of macroreentrant tachycardia based on color-coded three-dimensional (3D) entrainment mapping and subsequent placement of strategic lesion lines.Twenty-six patients presented with macroreentrant tachycardia (cycle length 329 +/-...
