[Diagnostic sensitivity of 24-hour electrocardiographic Holter monitoring in indications for coronarography]. / Diagnostická citlivost' 24hodinového elektrokardiografického Holterovho monitorovania pre indikáciu na koronarografiu.

The authors evaluated 24-hour ECG monitoring (Holter monitoring) in 70 patients indicated for coronarography. They assessed the sensitivity, specificity, positive and negative predictive value of Holter monitoring. They compared the findings with data reported in the literature and with the sensitivity of the ergometric test for indication of patients for coronarographic examination. Although the sensitivity and specificity of Holter monitoring does not exceed generally reported values of sensitivity and specificity of bicycle ergometry, in the discussion the authors mention conditions where Holter monitoring is an asset for indication of patients for coronarographic examination.

[Transesophageal atrial stimulation in routine clinical practice]. / Transezofageálna stimulácia predsiení v beznej klinickej praxi.

The authors examined 90 patients by the method of transoesophageal atrial stimulation with different indications. They consider transoesophageal atrial stimulation a suitable method for basic examination of an impaired functional status of the sinoatrial node and atrioventricular conductivity. It is suitable for assessment of predisposition to supraventricular disorders of the rhythm and for testing the effectiveness of treatment of impaired supraventricular rhythm. The authors use it also for a modified loading test in patients with coronary heart disease. They evaluate transoesophagel al atrial stimulation as a simple, safe, non-invasive method, practically without contraindications, which extends our diagnostic and therapeutic possibilities, is not demanding from the technical and economic aspect and can be used in any hospital.
