title: Ultrasound for primary confirmation of mechanical capture in emergency transcutaneous pacing.
abstract: Clinical confirmation of mechanical capture in emergency transcutaneous pacing is sometimes difficult because of weak pulse volume or interference from skeletal muscle contractions. This report is of a case of using bedside ultrasound for primary confirmation of emergency transcutaneous pacemaker capture, and for differentiating between causes of persistent hypotension despite successful pacing. The technique of ultrasound-guided transcutaneous pacing is described.
