The electrograms suggest rate-dependent conduction block of CS-LA connections followed by induction of AF (A) or AFL (B). Annotations below each tracing indicate pacing location and CL. Panel A shows pacing from the lateral LA with rate-dependent CS-LA conduction block at CS 7,8 at 250 ms followed by AFL induction and degeneration to AF within 6 beats. Panel B shows pacing from lateral LA with rate-dependent CS-LA conduction block at CS 1,2 at 250 ms, followed by AFL induction.
