The administration of digitalis glycosides is followed by a consistent and dose-dependent abbreviation of the duration of left ventricular ejection in normal individuals. The changes in left ventricular ejection time determined from the indirect caro

The duration of the systolic time intervals in nondigitalized patients with heart failure was determined from simultaneous fast speed recordings of the electrocardiogram, phonocardiogram, and carotid arterial pulsation. These were compared with the s

Described here are seven cases of permanent transvenous pacemakers associated with a pacemaker click. The graphic findings and roentgenographic appearance of the catheter position are discussed. Although these cases appear to represent penetration at

In the present investigation we studied the effect of deslanoside on the duration of the phases of left ventricular systole as derived indirectly from simultaneous tracings of the electrocardiogram, the heart sounds and the external carotid arterial

The effects of beta adrenergic receptor blockade by propranolol on the hemodynamic responses to isoproterenol and epinephrine were investigated in 10 supine normal volunteers. Intravenous propranolol (10 mg.) lowered heart rate, cardiac output and st

The administration of deslanoside to normal subjects was associated with an abbreviation in the duration of all phases of mechanical systole in the absence of a change in cardiac output. The decrease in the ejection time index following deslanoside i

Characteristic changes in the systolic intervals of the left ventricle have been demonstrated among patients with arteriosclerotic, hypertensive and primary myocardial disease. These consist of a prolongation of the pre-ejection period and an abbrevi

1.1. The administration of deslanoside to normal subjects is associated with a highly significant shortening of the ejection time index. 2.2. The reduction in serum ionizable calcium induced by the administration of Na 2 EDTA to digitalized subjects

Experience with 200 consecutive patients who received temporary pacemaker treatment during a 14-month period demonstrated that aside from complete heart block, this mode of therapy can be effective in sinus bradycardia, in S-A arrest, block or stands

We have investigated the possibility that alterations in the duration of the systolic preejection period can be used to estimate adrenergic influences on the human left ventricle. The preejection period was determined from high speed, simultaneous re
