Abstract:
There are some disadvantages in the traditional ECG exercise, such as noises in the acquired ECG, restrictions on the kind of patient who can use this method and the low sensitivity and specificity for the ST depression diagnostic metrics. New equipment for diagnosing Chronic Myocardial Ischemia based on ST/HR slope and power test bicycle is designed. The ST/HR slope is calculated with computer software, avoiding heavy burden and errors for human computation. The power test bicycle decreased noises and improved other disadvantages for treadmill. It is demonstrated with experiments that this system yields better performance with higher sensitivity (93.8) and specificity (94.5) than the traditional system does.
