    Author: Bernard P, Chaitman BR, Scholl JM, Val PG, Chabot M.
    Journal: J Electrocardiol; 1983 Jan; 16(1):97-103. PubMed ID: 6220102.
    Abstract:
    One thousand consecutive ECG's from an ambulatory population of patients with suspected or proven cardiac disease were evaluated using two versions of the Telemed computerized ECG system. Only minor differences were found between the two programs. In version 6 vs. version 5, 87% vs. 90% of 287 normal ECG's were correctly classified and 93% vs. 96% of abnormal ECG's were correctly classified; the percent of acceptable diagnostic agreement was 86.2% and 87.4% respectively (NS). The sensitivity for arrhythmia detection, transmural inferior infarction and ST-T wave abnormalities was slightly greater in version 6. The increased sensitivity was not accompanied by decreased specificity. The sensitivity for left ventricular hypertrophy decreased from 95.2% to 91.4% in version 6 with a slight increase in specificity (95.2% to 97.0%). In conclusion, criteria changes in the most recent version of the Telemed program have not resulted in a major change in diagnostic performance. Arrhythmia detection is slightly but not significantly improved.
