Detection of a temporary cardiac pacing catheter in the left ventricle by chest X-ray

This is the first reported case of detection by chest radiograph of a temporary cardiac pacing catheter inadvertently placed in the left ventricle. The unusual catheter position seen in the first chest radiograph was confirmed by a second film following reinsertion of the catheter into the right ventricle. The importance of roentgenographic confirmation of temporary cardiac pacing catheters, especially those inserted without fluoroscopy, is reemphasized.
