Figure 3

Representative high density activation map of the LA (A) and electrograms (B) demonstrating CS-LA connections during low output distal CS pacing (CS 1–2). Panel A demonstrates 2 distinct sites of early activation in the LA overlying the distal CS and the proximal CS when pacing the distal CS at a cycle length of 900 ms. Panel B displays the earliest LA electrograms (Lasso 15,16 and 17–18 on panel A), which demonstrate delay compared to the stimulus and rule out direct LA capture. LAO: left anterior oblique; CS: coronary sinus
