The objective of this study was to determine the efficacy of using 2-dimensional ultrasound (US) in determining the presence of ventricular capture of an external cardiac pacemaker in a swine model. Five anesthetized swine underwent external cardiac pacing (ECP) at variable levels of energy output while concurrent US images and electrocardiograph monitoring were recorded on videotape. Determinations of capture/no capture were made in the laboratory. Segments of videotape were selected to be reviewed by 2 physicians blinded to these laboratory determinations of capture and to each other. Kappa levels of agreement were determined among the 3 pairs of comparisons. Seventeen segments were reviewed. Kappa levels of agreement were 0.76 for Reviewer A versus Laboratory determination, 0.88 for Reviewer B versus Laboratory determination, and 0.88 for Reviewer A versus Reviewer B. All P values were <.001. These excellent levels of agreement show that 2D US in this animal model is highly effective in determining the presence of ventricular capture in ECP.<p> Observer Variation Reproducibility of Results Animals Pilot Projects Electrocardiography Monitoring, Physiologic/*methods 13306 public 2022-02-21T22:48:57.408-06:00 *Echocardiography 19 Bradycardia/*therapy 2 Heart Ventricles/*diagnostic imaging document-rn18426 10.1053/ajem.2001.19988
