Abstract
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.Results Analysis of QTc interval detected a prolonged QTc interval >500 msec in 8.2 % of cases, prolonged QTc >480 msec in 18.3 % f cases, and prolonged QTc interval >60 msec compared to baseline in 12.2 % of cases.Conclusion Remote recording of single-channel ECG using a portable electrocardiograph is an effective method for recording and detecting various forms of heart rhythm disorders.
