Figure 7. Clinical Impact of timing window on AF maps.

Figure 7

A) Three consecutive cycles of AF are shown in a 70-year-old female, as voltages and –dv/dt. The blue box represents one AF cycle (190ms), with electrograms spanning 100% of the AF cycle in all channels in a rotational circuit (i). Moving this box 15ms earlier (orange box) now shows focal activity (starting with F6) with activity spanning only 140ms (ii). Morphology (qS) did not indicate focal activity (cycles 2 and 3). Ablation at FG34 (from blue window) acutely terminated AF.
