Description

The clinical evaluation of the AIDA algorithm loaded into a dual chamber pacemaker. The importance of controlling arrhythmias following pacemaker implantation is well known. However, 24hr Holter ECGs and ambulatory ECGs often fail to detect paroxysmal arrhythmias. In this study, we prospectively evaluated the clinical usefulness of the AIDA (Automatic Interpretation for Diagnosis Assistance) loaded into a dual chamber pacemaker. Patients and Method: Fourteen patients, 9 AV Block and 5 SSS, were enrolled. Three of them showed documented paroxysmal atrial fibrillation before operation. The study was divided into two periods as D1 and D28During the D1follow-up the pacemaker data recorded with the AIDA program over 24 hours was compared with that of a simultaneous surface Holter recording. The prevalence of atrial arrhythmias at D28was calculated from the data recorded over the previous 28 days and automatically analyzed by the AIDA program. Result: Eighteen atrial arrhythmias were successfully recorded in 8 patients by the AIDA program and coincided with simultaneous surface Holter ECGs at D1.A large incidence of asymptomatic arrhythmia was demonstrated by using the AIDA program in patients without prior history of atrial arrhythmia at D28 Conclusion: The AIDA study demonstrated that the AIDA program of a pacemaker is useful to evaluate the prevalence of arrhythmias, especially the detection of asymptomatic anythmias. In addition, drug therapy maybe better assessed using this AIDAprogram.
