CTICasesHis Bundle Pacing
Imaging findings
Chest radiograph shows three pacemaker leads: two in standard positions and one lead positioned medially and anteriorly at the interventricular septum, corresponding to the expected anatomical location of the bundle of His.
Key takeaways
His bundle pacing is an alternative pacing strategy where a lead is placed directly at the bundle of His to provide physiologic, synchronous ventricular activation. On radiographs, the lead is positioned more medially and anteriorly than standard right ventricular apical leads.
