title: [Diagnosis of syndrome X using comprehensive analysis of the electrical field of the heart].
abstract: The authors describe the clinical picture and results of some auxiliary examinations in 18 patients with the X syndrome, i.e. with angina pectoris with a normal angiographic finding on the coronary arteries. For the diagnosis of ischemic cardiac changes, which are an integral part of this syndrome, the authors used a complex analysis of the electric cardiac field by means of a Cardiac 128.1 apparatus (manufactured by ZPA-Cakovice). In patients with the X syndrome they observed a significant reduction of some potential and integral values, as compared with an equally sized group of healthy subjects. On maps of the electric manifestation of cardiac activity on the chest surface ischemic changes were revealed on the antrior and lower cardiac wall but also in its lateral and posterior wall. These changes were older and were found in the subendocardial layer or concurrently in another area of the heart with affection of the subepicardial layer. Minor non-transmural fibroses, most frequently on the septum, in some instances spreading to the anterior and lower cardiac wall, were a surprising finding. At present it is not possible to differentiate merely by analysis of the electric cardiac field the X syndrome and ischemic heart disease. This should be made possible by further comparative studies. The present paper is the first description of ischemic and fibrous cardiac changes in X syndrome diagnosed by a complex analysis of the electric cardiac field in the professional literature published in Czechoslovakia and other countries.
