RESUMO
A computer-assisted system has been developed to store, retrieve and analyze medical and surgical data on patients undergoing coronary bypass surgery. The analysis ranges from a simple summary tabulation to a more advanced prognostic evaluation of the risk of coronary bypass in an individual candidate for the operation. Data can be displayed on the terminal's screen or printed in a hard copy and used for clinical or administrative purposes. The system can be operated with no knowledge of computers or programming and requires only minimal typing skills.

Coronary artery bypass surgery was performed in 92 patients, ranging in age from 20 to 40 years. The male-to-female ratio was 5:1. The operative mortality was 3.3%. Sixty-two patients were followed up for a mean of 3.5 years. Complete relief of angina was reported by 79% of patients and an additional 10% experienced some improvement. The survival rate at 3.5 years was 97%. The results favour myocardial revascularization in young adults.

Vectorcardiographic loops can be evaluated with the help of transparent overlays depicting normal ranges for the magnitude and orientation of various P, QRS and T vectors in each of the three conventional planes. By appropriate positioning of such overlays over vectorcardiographic loops it is possible to determine in a matter of seconds whether or not the magnitude and/or orientation of various vectors are within normal limits.

The amplitude of ECG wave forms can be evaluated rapidly and accurately with the help of a transparent overlay depicting images of the P-QRS-T complex in various leads. Such images are drawn between the upper and lower limits of normal amplitude values and by placing them over the corresponding P-QRS-T complexes in the patient's record it is possible to determine in a matter of seconds whether various deflections are within normal limits.

A graph consisting of small squares of equal size preprinted on a transparent plastic chart can be used for a quick and accurate calculation of the VCG loop area in each quadrant of the three conventional planes.

A simple scale, which allows the ECG reader to assess the regularity of the RR (or PP) interval and to detect the P wave train, has been presented.
