The Use of Electrical Impedance Research Method to Assess the Heart Response to Drug Treatment

The article discusses the possibility of using the multichannel precordial electro-impedance method for studying the heart activity phase structure to assess the effect of various medical therapeutic drugs on the heart activity in the treatment of patients with lymphomas. As a result, it was found that after 3-4 days after the start of the course, drug treatment has a significant effect on the activity of the human heart. The most responsive indicators are the durations of atria and ventricles pre-ejection periods. But the influence of chemotherapy in some cases can lead to an improvement in certain parameters of the heart activity phase structure. The considered electrical impedance research method can be an informative tool to control the effect of drug treatment. However, at this stage, there is not enough data about changes in heart activity phase structure during the treatment course to form an informed opinion about the drug effect.
