[Hemodynamics, left ventricular volumes and compliance in 167 patients with congenital and acquired heart disease (author's transl)].
In 167 patients with congenital and acquired heart disease (ventricular septum defect (VSD), atrial septum defect (ASD), mitral stenosis (MS), mitral insufficiency (MI), combined mitral stenosis and insufficiency (MV) aortic stenosis (AS), aortic insufficiency (AI), combined aortic stenosis and insufficiency (AV), idiopathic hypertrophic subaortic stenosis (HOK) hemodynamic measures (arterial pressure, right and left heart pressures, cardiac output, cardiac index, stroke volume, cardiac work), left ventricular volumes (endiastolic volume, endsystolic volume, ejection fraction, regurgitant flow) and diastolic pressure-volume relationships (on the basis of diastolic pressure-volume changes) were determined during routine right and left heart catheterization and left ventriculography. 1...

[Effect of sparteine sulfate on the predamaged conduction system of the heart].
Antiarrhythmic drugs are known to cause AV-blockade. In animals and healthy humans the alcaloid of the gorse sparteine sulphate has been reported not to cause those side effects. We have studied in 10 patients with predamaged conduction system the grade of AV-blockade, the AV-interval and the intraventricular excitation spread by e.c.g. after i.v. injection of 200 mg sparteine sulphate (ajmalin, 50 mg i.v. as control). In 6 out of 10 patients no side effects have been observed. In 4 patients both sparteine and ajmalin injection caused higher graded AV-blockade. Our results suggest that sparteine sulphate like other antiarrhythmic drugs should not be administered to patients with a predamaged conduction system.
