Figure 3 High-Resolution Mapping Confirms Atrial Activation Time
(A) Focal AT (lateral RA). The ECG dV/dt estimated P-wave duration is 127 ms; mapped atrial activation is 125 ms. The ECG autocorrelation CL (284 ms) closely estimated measured CL (274 ms). (B) Lower loop macro–re-entrant AT (same patient as in Fig. 2B). The ECG dV/dt-estimated F-wave duration is 171 ms and mapped atrial activation is 181 ms; ECG autocorrelation CL is 236 ms versus measured CL 239 ms (Fig. 2B). Abbreviations as in Figure 1.
