[Remote Monitoring of the QT Interval During Polychemotherapy].

Aim      To evaluate the incidence of prolonged corrected QT interval (QTc) by remote single-channel electrocardiogram (ECG) monitoring in primary oncological patients with elective polychemotherapy (PCT).Material and methods  This study included 49 oncological patients with elective PCT. A single-channel portable CardioQVARK electrocardiograph was used to record single-channel, one-lead ECG between the first and second courses of PCT.

[Exhaled Breath Analysis in Diagnostics of Cardiovascular Diseases].

Exhaled breath analysis is a novel tool for diagnostics of different diseases. Taking into account the secretory function of the lungs, the composition of exhaled breath is different in physiological and pathological conditions. In this review we consider of some substances which content vary in cardiovascular diseases - pentane, isoprene, carbon monoxide and trimethylamine.

Until today, there are no universally accepted methods for detection of unstable atherosclerotic plaques, even though many recent studies were devoted to this issue. In this article we present modern possibilities of computed tomography in visualization of atherosclerotic coronary lesion, including the detection of unstable lesions, whot in turn, can help in diagnosing subclinical exacerbation of ischemic heart disease and in the stratification of risks of acute coronary events.

Nowadays an invasive evaluation of fractional flow reserve (FFR) is one of the main methods used for detecting lesions that cause ischemia. Invasively obtained FFR <0.75 has the specificity of 100 %, and FFR >0.
