Electrocardiographic detection of left ventricular hypertrophy in the presence of left anterior fascicular block.

The hitherto available electrocardiographic indexes for the detection of left ventricular hypertrophy in the presence of left anterior fascicular block do not provide a reliable diagnosis. Consequently, a new index based on the behavior of the QRS complex in left anterior fascicular block in the frontal and horizontal plane was constructed and its value assessed by echocardiographic measurements. The new index SIII + (R + S) maximal precordial greater than or equal to 30 mm was applied to the electrocardiograms of 50 patients without myocardial infarction and without right bundle branch block, showing a specificity of 87%, a sensitivity of 96%, a positive predictive value of 89% and a negative predictive value of 95%.

[ECG diagnosis of left ventricular hypertrophy associated with a left anterior fascicular block].

The hitherto available ECG indices for the detection of left ventricular hypertrophy in the presence of left anterior fascicular block do not provide a reliable diagnosis. We have therefore constructed a new ECG index, based on vectorcardiographic considerations, and assessed its value by echocardiographic measurements. The new ECG index SIII + (R + S)max precordial greater than or equal to 30 mm, applied to the ECGs of 50 patients without myocardial infarction and without right bundle branch block, showed a specificity of 87.

Hemodynamic changes after angiocardiography with a new low osmolar contrast medium (sodium-meglumin-joxaglat).

We evaluated the hemodynamic effects of sodium-meglumin-joxaglat (Hexabrix) compared to sodium-meglumin-diatrizoat (Urografin 76) after left ventriculography in a double-blind randomized study on 24 patients (12 patients per group). Hemodynamic measurements at rest and the extent of ischemic heart disease were comparable in the two groups. Measurements were made at rest and between the second and third minute, between the fifth and sixth minute, and between the eighth and ninth minute following injection of 0.

Apoproteins and lipids as discriminators of severity of coronary heart disease.

Serum apoprotein and lipid concentrations were measured in 63 patients undergoing coronary angiography. Thirty-eight patients had 50% or higher grade stenoses, 25 had chest pain, but no significant stenoses. Among the patients with higher grade stenoses 71% had hyperlipoproteinemias as opposed to 12% in patients without stenoses.
