Abstract

Because in patients with the recent myocardial infarction the noticeable differences in the P wave and PQ interval dispersion were observed in comparison to the control group, consisted of the healthy persons, it was an intresting problem to define the period of persistence of these visible changes on the electrocardiograms made in patients after the myocardial infarction. The aim of the study was to estimate the P wave and PQ interval dispersion in patients after the myocardial infarction in dependence on its location and applied fibrynolytical treatment. The investigations were conducted on 36 male and female patients in age 40 to 84 years (mean 56 +/- 10,8 years), divided into groups of patients suffering from the inferior myocardial infarction and anterior myocardial infarction. The estimation of P wave and PQ interval dispersion was made by two independent researches on the 12 offtake electrocardiogram, by using scanner and computer program Photo-Finish. There were analysed electrocardiograms made in 10th day, 6 weeks of recovery and successively in 3rd, 6th, and 12th month after the recovery. During the each investigation the echocardiography was made to state the dimension of the left atrium and the blood samples was tak...Continue Reading

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
