Septum perforation and lead dislodgement cases.

Case No.	Age	Gender	Diagnosis	Complication	Abnormal pacing parameters	Treatment and outcome
1	78	Male	Sick sinus syndrome with paroxysmal atrial fibrillation	Septum perforation at 1-month follow-up	Threshold: >5.0 V/0.5 ms (unipolar) 2.5 V/0.5 ms (bipolar) Impedance: <300 Ω (unipolar)	The lead was repositioned to a more distal LBB area at posterior septum
2	76	Female	Atrial fibrillation with low ventricular rate	Septum perforation at the second day post-procedure	loss of capture at the high output (>7.5 V/0.5 ms)	A new lead (Model 5076) was implanted and replaced at RV apex
3	77	Female	Complete AVB	Lead dislodgement	loss of capture at the high output (>7.5 V/0.5 ms)	The lead was replaced to another LBB region with proper slack
4	64	Male	Complete AVB and atrial fibrillation	Lead dislodgement at 1-month follow-up and the lead dislodgement occurred again at 5-month after reposition.	loss of capture at the high output (>7.5 V/0.5 ms)	The lead was replaced to another LBB region but dislodged again Finally another lead (Model 5076) was repositioned at RV septum
