Correlaçäo entre as características eletrocardiográficas da onda P e a pressäo diastólica final do ventrículo esquerdo em repouso e em exercício / Correlation between the electrocardiographyc characteristics of P nave and the left ventricular final diastolic pressure atrest and in stress

ABSTRACT

The authors studied 60 patients with congestive heart failure and sistemic arterial hypertension, the relationship between the P - wave caracteristics and the left ventricle end - diastolic pressure, in rest and at exercice. Among several criterias, they found out that the P - termianl force in VI (Morris'Index) was the best eletrocardiographic criteria of left atrial enlargement when compared with the left ventricle end diastolic pressure in rest and, specialy, at exercise
