When the doctor takes your BP, they measure two numbers. The top number is calledthe systolicand the bottom number are called thediastolic. Anormal blood pressureof 120 over 80. If your numbers are above these, you may have pre-hypertension stage or hypertension depending upon your age. If ...
Only the minimum diastolic blood pressure/systolic blood pressure ratio (D/S ratio) during the first 24 h after admission remained as an independent predictor of progression to septic shock and 28-day mortality. The best cutoff values of the D/S ratio for predicting septic shock and 28-day ...
Blood Pressure Chart: Systolic and diastolic numbers for heart health and diagnosis. How to Measure Systolic and Diastolic Blood Pressure Numbers A doctor or nurse will take your blood pressure with a small gauge attached to an inflatable cuff. It's simple and painless. ...
When these intervals and the pre-ejection period/ejection time ratio were compared to corresponding values obtained by conventional methods from the simultaneously recorded phonocardiograms and indirect carotid pulses, a high degree of correlation (r > 0.97) was found. Differences between the two ...
Variable selection was stopped when the likelihood ratio test was no longer significant (p < 0.05). All two-way interactions of clinical interest were tested for significance. Additionally, stratified analyses were performed, and adjusted odds ratios for gender were calculated, stratified by age and...
The renal RI was calculated as (peak systolic velocity – minimum diastolic velocity)/peak systolic velocity24. The renal PEP (rPEP) was meas- ured from the onset of the QRS complex to the foot of the renal pulse Doppler waveform. The renal ET (rET) was measured from the foot to the...
(point C-D), opening of themitral valveand initiation of diastolic filling (point D), and diastolic filling (point D-A). The loop width is stroke volume, the ratio of width to end-diastolic volume is EF, and the loop area is external (or stroke) work. When ventricular preload is ...
Thanks to its simplicity, the time-varying elastance theory has been used in many lumped mathematical models of the cardiovascular system. This theory has been extended to better reproduce the diastolic properties of the heart [2,3]. A great advantage of this concept is that it allows fast mod...
Scatter plots of left ventricular end-diastolic diameter (LVEDD, (A)), left ventricular end-systolic (LVESD, (B)) and left ventricular ejection fraction (LVEF, (C)) plotted over time in patients with AIC (arrhythmia-induced cardiomyopathy, open circles) and non-AIC (solid circles); AF = ...
