[[File:X-ray of pacemaker with right atrial and ventricular lead.jpg|thumb|350px|Pacemaker with normally located leads in the right atrium (white arrow) and right ventricle (black arrowhead), respectively.]]
==Planning==
[[X-ray of the chest]] is often (but not always) done routinely the day after pacemaker insertion, both to check the positions of the electrodes as well as to exclude the complication of pneumothorax (see [[X-ray of pneumothorax]]).<ref name="pmid25815303">{{cite journal| author=Kotsakou M, Kioumis I, Lazaridis G, Pitsiou G, Lampaki S, Papaiwannou A et al.| title=Pacemaker insertion. | journal=Ann Transl Med | year= 2015 | volume= 3 | issue= 3 | pages= 42 | pmid=25815303 | doi=10.3978/j.issn.2305-5839.2015.02.06 | pmc=4356861 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=25815303}}</ref>
==Evaluation==
;Atrial lead
For right atrial and right ventricular leads for single-chamber and dual-chamber pacemakers, the right atrial lead should demonstrate a "J-shaped" on lateral view, appearance since it curves upward and anteriorly in the right atrial appendage.<ref name="AguileraVolokhina2011">{{cite journal|last1=Aguilera|first1=Amanda L.|last2=Volokhina|first2=Yulia V.|last3=Fisher|first3=Kendra L.|title=Radiography of Cardiac Conduction Devices: A Comprehensive Review|journal=RadioGraphics|volume=31|issue=6|year=2011|pages=1669–1682|issn=0271-5333|doi=10.1148/rg.316115529}}</ref>
The tip of the right ventricular lead should be to the left of the spine on frontal view. In lateral view, it should course anteriorly into the apex of the right ventricle.<ref name="AguileraVolokhina2011"/>
==ReferencesReporting==In every X-ray where a pacemaker is present, it is apt to describe the corresponding atrium or ventricle of the electrode location, and acceptable to not comment the positioning of the electrode tip unless it is misaligned, or specifically requested in the referral.{{reflistBottom}}
