| 摘要 |
<p>This invention relates to a non-invasive cardiac device (10) which can be inserted through the esophagus and into the gastroesophageal junction region. Once in place, a selected portion of the device is urged adjacent the cardiac region. The device comprises an elongated conduit (12) having a series of electrodes (26) for sensing or recording electrical signals. A first means (18) for positioning the device adjacent the gastroesophageal region is located adjacent a first end (14) of the device. The device further includes a second means (20) for positioning the device in the esophagus such that at least some of the electrodes (26) are urged adjacent the cardiac region.</p> |
