Example of Bidirectional Blocks Between the MB and LA Connections in Case 3 (A) Both activation sequences of the CS and VOM were proximal to distal during LAA pacing. (B) With the differential pacing site method, the conduction time from VOM 1 to 2 to LAA (175 ms) during VOM 1 to 2 pacing was longer than the conduction time from VOM 5 to 6 to LAA (165 ms) during VOM 5 to 6 pacing. These observations were evidence of complete bidirectional block of MB-LA connections. Note: The earliest activation site of the CS during VOM pacing was CS 3 to 4, which indicated disconnection of the MB–distal CS connections. Abbreviations as in Figure 1.
