Electrocardiographic diagnosis of chamber enlargement

Left atrial enlargement. Echocardiographic assessment of electrocardiographic criteria.

A comparison of electrocardiographic manifestations of left atrial enlargement (LAE) and left atrial size by echocardiography was made in 307 patients in sinus rhythm. Electrocardiographic criteria used were L:P wave duration in lead II equal to or greater than 0.12 sec; Va: the ratio of the duration of negative terminal P in V1 to the P-R segment equal to or greater than 1.0; Vb: a negative P ...

A method for the electrocardiographic recognition of atrial enlargement.

New criteria for the electrocardiographic recognition of right atrial enlargement, left atrial enlargement, and combined atrial enlargement were studied in 110 patients with congenital and acquired heart disease. Precise physiologic data weife available in all cases. The method of analysis was designed for application to conventional scalar electrocardiography and hence can be used without modi...

Electrocardiographic Diagnosis ofMyocardial Infarction

It is generally accepted that most myocardial infarctions are obscured on the electrocardiogram by left bundle-branch block. The number of published cases in which this could be evaluated, however, is small, and the case reports are scattered. We have studied 30 cases of myocardial infarction with left bundle-branch block in which the location of the infarction could be determined with certaint...
