Abstract
Patients with suspected Adams-Stokes syndrome are examined by Holter Monitoring. During the monitoring, there is the danger of syncopes and there have even been reports of sudden cardiac deaths. We have developed the pacemaker for the prevention of Adams-Stokes syndrome and sudden cardiac death while monitoring asystoles. The pacemaker has the following functions; 1) the longest escape interval of the pacemaker which is not more than the value inducing syncope is determined by the mean heart rate including the asystole, 2) once the pacemaker escapes, it continues pacing for a while at a physiological rate to cancell ischemias in organ tissues, 3) to prevent the overdrive suppression to the heart, pacing rate gradually declines and stops pacing until the next asystole. This pacemaker is useful not only in the diagnosis of Adams-Stokes syndrome, but also in the pathophysiological study and to know the time to quit pacing.
