| Abstract | ||
| ABSTRACT This study was conducted on (20) twenty men with chronic renal failure , and they weekly treated with heamodialysis , and they are fallowed up from the first heamodialysis process after diagnosis for (10) ten consecutive weeks for each of them . The objective of this study is to investigate the effect of heamodiaylsis on electrical cardiac activity and concentrations of some ions which are related to the cardiac activity which are calcium , potassium and sodium . This objective was done by electrocardiography for each patient directly after heamodialysis and take blood sample to isolate plasma by centrifugation for measurement of calsium ,potassium and sodium . This repeated weekly for ten weeks .the results revealed that there is significant increase in (P-R) duration of ECG ,while there is no clear changes in other durations which are include (P) , (Q-R-S) and (Q-T) duration . Also there is no changes in voltages of waves of ECG which are include (P) ,(Q-R-S) and (T) . Heart rate give oscillation during weeks of research with out significant changes . Concentration of calcium give significant decrease starting from sixth week to the end of the research , while there is no changes in concentrations of potassium and sodium . These results indicate changes in cardiac electrical activity which 55 are represented by increase in (P-R) duration because the tissues of the heart including conductive tissues are affected by heamodialysis which may be indicate starting of heart block in transmission of pulse ,which may be lead to heart failure due to repeated heamodialysis . While decrease in calcium concentration indicate increase lose of this ion by continuous heamodialysis . | ||
