    Representative example of an induced ExPVT from the LA septum during isoproterenol provocation test. ( A ) <t>Intracardiac</t> electrograms showing AF initiation by an ExPVT induced during provocation. The earliest activation (circle marked by a pointed arrow) is recorded by the circular mapping catheter positioned at the LA septum, consistent with panels D and E . ( B ) Fluoroscopic image (AP view) showing a left atriogram with pulmonary venogram and initial positioning of multielectrode diagnostic catheters. ( C ) Standardized catheter configuration (AP view) during provocation testing, including a quadripolar catheter in the SVC, a decapolar across the high RA and septum, and a duodecapolar along the CS and low RA. A PV mapping catheter, typically positioned at the LA posterior wall, varied in type depending on availability, operator preference, and patient characteristics. ( D ) Electroanatomical activation map identifying the earliest trigger point (white arrow) of the ExPVT from the LA septum. ( E ) Electroanatomical voltage map showing a low-voltage area at the LA septum compatible with the AF trigger site. Abbreviations: AF, atrial fibrillation; AP, anterior posterior; CS, coronary sinus; ExPVT, extra-pulmonary vein trigger; HRA, high right atrium; LA, left atrium; LRA, low right atrium; PV, pulmonary vein; RA, right atrium; SR, sinus rhythm; SVC, superior vena cava.
