stiffness by deriving the pressure–diameter curve of the artery (the measurements of changes in diameter over the cardiac cycle and the local pulse pressure (PP) should be determined simultaneously) and calculating local arterial stiffness from the time delay between two adjacent distension waveforms....
Sex Differences in Long-Term Survival After Major Cardiac Surgery: A Population-Based Cohort Study. Background Little attention has been paid to the importance of sex in the long-term prognosis of patients undergoing cardiac surgery. Methods and Results W... A Johnston,T Mesana,D Lee,... -...
The originality of the presented work mainly lies in the last two steps that result in a 4-D tomographic representation, allowing for the visualization of coronary arteries anatomy from any point of view, and at any cardiac cycle time. Experiments have been conducted on one synthetic data set ...
The study of the phases of the cardiac cycle is important in evaluating the functional state of cardiac muscle. Cardiac phases may be studied by simultaneously performing an electrocardiogram and phonocardiogram and measuring the pulse of one of the large arteries near the heart. The volume of ...
On an ECG of the complete cardiac cycle, at which portion of the R-R interval is the heart muscle in diastole? vacuum phenomenon The accumulation of gas within a degenerating intervertebral disc is called the: 1 and 3 only During a spiral or helical CT examination, the scanner acquires dat...
(who was already sporting a beard) who loved teasing and joking around was to be my new student. This young man had heart surgery just hours after his entrance into this world. He had neurological, skeletal, cardiac and breathing issues. The doctors told his parents their son might never ...
In anesthetized dogs, intravenous bolus injections of amrinone at doses ranging from 1 to 10 mg/kg caused increases in cardiac contractile force and left ventricular dp/dt max with relatively small changes in heart rate and blood pressure. No significant changes in lead II ECG were observed. ...
various nerve areas connected with contraction are located in the heart (see HEART, CARDIAC CYCLE): (i) the sinoatrial node (SAN) or ‘pacemaker’ located in the wall of the right atrium near the entry of the venae cavae; (ii) the atrioventricular node (AVN) at the junction of all four...
• Solid organ transplant: Although data is limited, serious medical complications have been reported in females with complicated organ transplants (eg, graft failure, rejection, cardiac allograft vasculopathy); use of combination hormonal contraceptives is not recommended in females with complicated orga...
