DM DOC 040 Rev 1.0
Results of rhythm interpretations. Several databases were used. The first was the
Glasgow 1000 ECG database. A second database of 1498 ECGs from apparently healthy
adults was also incorporated to increase the number of sinus and other common rhythms.
These ECGs were supplemented by 72 cases of atrial fibrillation which were included to
augment the number of cases of this arrhythmia.
