Evaluation of the state of health of subjects with W-P-W syndrome.

Topical questions in evaluating the state of health in the least risk-exposed group of subjects with the W-P-W syndrome are dealt with: the recognition of preexcitation, the possibility of confusing the W-P-W syndrome with the postinfarction state, the occurrence of abnormal T waves after suppression of preexcitation, and the ECG dynamics after physical exercise. On the basis of ECG and normal results of non-invasive polygraphic examination (systole phase analysis--systolic time intervals) it is possible to divide the least-risk group of persons with preexcitation (with an otherwise normal heart and without paroxysmal tachycardia) into five subgroups (with growing risk) and to evaluate the ability of a person with preexcitation to engage in sports; to carry out military service etc. The mentioned non-invasive examinations are the basic prerequisites in every subject with the W-P-W syndrome and in symptomatic patients before more detailed electrophysiological examination.
