Conclusion
Pacemaker and ICD implantation is a useful therapy for many arrythmias,
but proper review of all indications is required. Additionally,
consistent follow-up and comments on positioning of the lead is
necessary, as inadvertent placement of a pacemaker or ICD into the left
ventricle is a rare but under-reported complication that carries a high
risk of thromboembolic events and must be diagnosed and treated quickly.
There are various methods useful in recognizing such a complication,
including ECG, AP and lateral chest X-rays, TEEs, or CT scans.
