Relationship between left ventricular ejection fractions and electrocardiographic variations in chronic chagasic patients

Abstract

The sistodiastolic dysfunction of the heart measured through global ejection of the left ventricle as systolic parameter and the ventricular rapid filling plus the time of ventricular total filling as parameters of function diastólica are informational facts of complementary examinations of high sensibility and specificity for this type of study. It was established a relationship between the fraction of left ventricular ejection global and segment, measured for ventriculografía radioisotópica of balance, with the disorders electrocardiográficos in chronic chagásic patients. It is possible to conclude that while major alteration exists in the fraction of ventricular ejection, major abnormal variations exist in the electrocardiography of the chronical chagasic patients. Those who presented complete block of right branch show the possible existence of association in the deterioration of the fraction of ejection apicoseptal, aspect that would allow to conclude that the complete blockade of right branch can be a variable predisposed. The statistical analysis of the fraction of ejection apical that was found shows that the decrease of this region has a statistical force with the electrocardiografic deterioration complete blockade of right branch more front left hemibloqueo, This scientific evidence is confirmed across the statistical and epidemiological evidence which indicators allow to observe a major prevalency in 66 % and a major association of 1.51 times of complete Blockade of Right Branch more front left hemibloqueo in relation to other segments.
