Figure 1. Epicardial optical mapping of the intact human atria.

Figure 1

A, Schematic of the four epicardial cameras’ optical fields of view. B, Representative optical action potential from the lateral RA (location indicated with circled #1 in panel D) of human Heart #1 (Case No. 947202). C, Average APD80 of RA vs LA at baseline, 10μM adenosine, 100μM adenosine and tertiapin of all bi-atrial preparations (n=11). Values are presented as mean±SD. * denotes p<0.05 vs baseline, # denotes p<0.05 vs LA. D, Activation (top) and APD80 (bottom) maps of Heart #1(947202) at baseline, 10μM adenosine, 100μM adenosine and 10nM tertiapin perfusion. Abbreviations: Ado – adenosine; BB – Bachmann’s bundle; CS – coronary sinus; CT – crista terminalis; IAS – interatrial septum; IVC – inferior vena cava; LAA – left atrial appendages; LRA – lateral right atria; PLA – posterior left atria; RAA – right atrial appendages; SAN – sinoatrial node; SVC – superior vena cava.
