ECG Multilead QT Interval Estimation Using Support Vector Machines
Table 1
Validation of QT estimation using the Physionet database. The parameter is represented as mean ± std. (min., max.).
| | Group | QT phy. (msec) | QT est. (msec) | Error (%) |
| | Physionet dataset | (317, 477) | (316.9, 474.6) | (0, 14.11) | | Control subjects | (317, 477) | (316.9, 474.6) | (0, 9.22) | | Myocardial hypertrophy | (317, 426) | (321.3, 438.1) | (1.42, 8.2) | | Valvular heart disease | (346, 426) | (344.3, 438.1) | (0.49, 14.11) | | Myocarditis | (385.5, 427.0) | (395.1, 418.5) | (0.27, 5.92) |
