Direct correlation of external systolic time intervals with internal indices of left ventricular function in man.
SUMMARY Direct correlation of extemally measured systolic time intervals with internally measured indices was obtained using catheter-tip micromanometers in six patients who had normal coronary arteriograms. Simultaneous recordings were made of central aorta and left ventricular pressure, maximum rate of rise in left ventricular pressure (dp/dt), external carotid pulse, external and internal so...
متن کاملLeft Ventricular Systolic Time Intervals
The effects of graded increments of passive head-up tilt on the duration of the systolic time intervals corrected for heart rate were investigated in 15 normal subjects. Head-up tilt caused a prolongation of the pre-ejection period and a shortening of the left ventricular ejection time, while total electromechanical systole diminished minimally. The lengthening of the pre-ejection period and ab...
متن کاملNormal left ventricular systolic time intervals assessed by pulsed wave Doppler echocardiography in the Turkmen horse of Iran
The Turkmen horse is one of the oldest and purest breeds in the world. There is no information with regards to the normal echocardiographic parameters of this horse regarding to cardiac diseases. Pulsed-wave (PW) Doppler echocardiography was performed on 42 clinically normal 3- to 15-year-old racing Turkmen horses. There were 26 stallions and 16 mares. The left ventricular isovolumetric contrac...
متن کاملThoracocardiographic-derived left ventricular systolic time intervals.
Thoracocardiography noninvasively estimates left ventricular performance by recording ventricular volume curves with inductive plethysmography. We studied timing of these curves to evaluate their potential to accurately track systolic time intervals in comparison with standard methods. Thoracocardiographic left ventricular volume curves, carotid pressure pulses determined by applanation tonomet...
متن کاملSystolic time intervals as measures of the contractile state of the left ventricular myocardium in man.
Previous studies relating systolic time intervals and measures of cardiac performance have suggested that the time intervals may be useful indices of myocardial contractility. To explore this possibility, systolic times and left ventricular (LV) performance and contractility were measured nearly simultaneously in 14 normal subjects and 56 patients with cardiac disease. Preejection period (PEP) ...
