Arterial hypertension as contributing factor to higher incidence of cardiac syncope

y. Cardiac syncope is characterized with a sudden loss of consciousness, most often without prior signs and symptoms, and the most frequent causes are disorders of cardiac conduction and rhythm. The aim of the work was to establish whether the existing arterial hypertension contributes to higher incidence of cardiac syncope. Forty two patients with cardiac syncope were examined. All of the patients had their anamnesis, physical examination, standard ECG and holter ECG monitoring done, on the basis of which the disorders of cardial conduction and rhythm were established as the causes of the cardiac syncope. All patients had regular neurological findings. The examination included 19 women of average age of 52.4 and 23 men of average age of 59.3. According to the findings - normal or increased arterial tension respectively, the patients were divided in two groups. The arterial hypertension and cardiac syncope were found in 29 (69.04%) patients (group A), while 13 (30.95%) patients had cardiac syncope and normal arterial tension (group B). In the group A, there were 5 (17.24%) patients with tachy-brady syndrome and, in the group B, there were 2 (15.38%); in the group A, there were 4 (13.79%) patients with AV nodal reentrant tachycardia and, in the group B, there were2 (15.38%); in the group A, there were 3 (10.34%) patients with bradycardia (heart frequency under 40 per minute), and in the group B, there was 1 (7.69%) patient; in the group A, there were 5 (17.24%) patients with VTs and, in the group B, there were3 (23.07%); in the group A, there were 6 (20.69%) patients with sinus pauses and, in the group B, there were 2 (15.38%); in the group A, there were 6 (20.69%) patients with A-V block of II/III degree and, in the group B, there were2 (15.38%). In patients with arterial hypertension, the cardiac syncope was more frequent as well as all individually analyzed disorders of the cardiac conduction and rhythm.
