Application of Multielectrode Mapping to Assess the Effect of Mechanical Right Atrium Distension on the Work of the Isolated Rat Heart

Abstract: The aim of the study was to assess the effect of mechanical right atrium distension of the isolated rat heart on the heart rate and heart rate variability, and the velocity of excitation wave propagation in the left ventricular myocardium using multielectrode mapping with flexible arrays. Materials and Methods. Experimental studies have been performed on the isolated rat heart in compliance with the Langendorff technique. Electrical heart activity was recorded using a flexible multielectrode array system. Resu… Show more

“…Important examples of such networks are related to the cardiac pacemakers (such as a sinoatrial node) incorporated in the surrounding excitable cardiac muscle as well as cardiac cell cultures studied in experiments [3][4][5][6][7]. Among the actual problems associated with such pacemaker nodes and cell cultures, there are possible effects of external mechanical action and underlying physiological mechanisms [8]. The two main mechanisms often considered involve the stretch-activated ionic channels and change of the local conductivity due to the tissue deformations [9][10][11][12][13].…”
