11000 exercise tests later-Was it worthwhile to computerize the procedure?

The effects of introducing computer-based electrocardiogram (ECG) recording equipment into an exercise test laboratory were evaluated in a multicenter study. After having used the new carts for two years, the staff were asked to compare them to the old equipment. The response was mostly positive, though major problems are still to be overcome until the new carts are fully accepted. Major advantages include enhanced online ECG presentation, resulting in a better surveillance of the patient. The interpretation of the exercise test is greatly facilitated by an improved report quality. The new cart is also very reliable from the operational point of view. System drawbacks include inaccurate handling of arrhythmia, too great a risk of total loss of data, and limited database facilities
