Successful External Cardioversion via Fluoroscopic Electrode Positioning in Patients with Enlarged Trans-Thoracic Diameter

  Figure 1.. LAO view. The left photograph depicts the electrodes placed in anteroposterior position. The larger circle is the anterior electrode and the smaller circle is the posterior electrode. This conventional positioning of electrodes failed to convert the patient to normal sinus rhythm. The right photograph depicts the electrodes placed by fluoroscopic guidance. The larger circle is the anterior electrode and the smaller circle is the posterior electrode. This position of the electrodes allowed the current to transverse between the electrodes through the atria and converted the patient to sinus rhythm.

  Figure 2.. RAO view. The left photograph depicts the electrodes placed in anteroposterior position. The larger circle is the anterior electrode and the smaller circle is the posterior electrode. This conventional positioning of electrodes failed to convert the patient to normal sinus rhythm. The right photograph depicts the electrodes placed by fluoroscopic guidance. The larger circle is the anterior electrode and the smaller circle is the posterior electrode. This position of the electrodes allowed the current to transverse between the electrodes through the atria and converted the patient to sinus rhythm.

  Figure 3.. The left photograph is the RAO view; the middle photograph is the AP view; the right photograph is the LAO view. The electrodes were placed under fluoroscopic guidance to ensure that the current between the electrodes traversed the atria efficiently. This positioning converted the patient to sinus rhythm.
