  • systolic
  • Further analysis of the ideal cycle indicated that the end-systolic P-V relationship (ESPVR) is an approximation to the adiabatic P-V trajectory that primarily determines total energy consumption. (biomedsearch.com)
  • Effect of positive inotropic agents on the relation between oxygen consumption and systolic pressure volume area in canine left ventricle. (semanticscholar.org)
  • Intracellular
  • Myocardial and hemodynamic effects of LY341311 were compared with dobutamine, a standard positive inotropic agent that acts via the β-receptor to increase intracellular cyclic AMP ( Tuttle and Mills, 1975 ). (aspetjournals.org)
  • Circulation
  • The main goals of hypothermic cardioplegia are: Immediate and sustained electromechanical quiescence Rapid and sustained homogeneous myocardial cooling Maintenance of therapeutic additives in effective concentrations Periodic washout of metabolic inhibitors The most common procedure for accomplishing asystole is infusing cold cardioplegic solution into the coronary circulation.

  • demand
  • CO is regulated principally by the demand for oxygen by the cells of the body. (wikipedia.org)
  • The theory behind this approach is that by simultaneously limiting the oxygen demand and maximizing oxygen delivery to the heart after damage has occurred, the heart is more fully able to recover. (wikipedia.org)
  • tissue
  • Gaseous signaling molecules are gaseous molecules that are either synthesised internally (endogenously) in the organism, tissue or cell or are received by the organism, tissue or cell from outside (say, from the atmosphere or hydrosphere, as in the case of oxygen) and that are used to transmit chemical signals which induce certain physiological or biochemical changes in the organism, tissue or cell. (wikipedia.org)
  • nitric oxide
  • Nitric oxide, known as the 'endothelium-derived relaxing factor', or 'EDRF', is biosynthesized endogenously from L-arginine, oxygen, and NADPH by various nitric oxide synthase (NOS) enzymes. (wikipedia.org)
  • A particularly important intermediate in the chemical industry, nitric oxide forms in mixtures of nitrogen and oxygen at high temperatures, as found in combustion systems such as internal-combustion piston engines, gas turbines, furnaces, and boilers. (wikipedia.org)
  • When exposed to oxygen, nitric oxide is converted into nitrogen dioxide. (wikipedia.org)
  • In water, nitric oxide reacts with oxygen and water to form HNO2 or nitrous acid. (wikipedia.org)
  • The nitric oxide reacts with the ozone to produce oxygen and nitrogen dioxide, accompanied with emission of light (chemiluminescence): ·NO + O3 → NO2 + O2 + hν which can be measured with a photodetector. (wikipedia.org)
  • Concentrations
  • Efaproxiral can be absorbed via transdermal, rectal, inhalation and gastrointestinal routes, though not at plasma concentrations great enough to alter the oxygen-haemoglobin dissociation curve. (wikipedia.org)
  • cardiac output
  • Thus, consideration of ventricular pressure-volume relationships highlight features that allow the heart to efficiently respond to any demand for cardiac output and oxygen delivery. (ubc.ca)
  • Thus, consideration ofventricular pressure-volume relationships highlightfeatures that allow the heart to efficiently respond toany demand for cardiac output and oxygen delivery.BackgroundThe heart is a muscle pump that delivers blood at a highpressure to drive passive blood flow through a complexarterial and venous circuit. (ubc.ca)
  • Calcium
  • For a complete list of events at the Farm, click onThey form updated to increase shop Let Us Talk of Many Things: The Collected Speeches by emotional vessels, result plan and duct, be or reject the important cord and is used with cylindrical carvedilol, control a myocardial Calcium of testing at function graft, or vary a physiological or vasodilator lineage opposite. (adams-farm.com)
  • But these are limited by adverse events, including arrhythmias related to increased myocardical oxygen consumption, desensitization of adrenergic receptors, and altering intracellular calcium levels. (wikipedia.org)
  • Thus omecamtiv mecarbil improves systolic function by increasing the systolic ejection duration/stroke volume, without consuming more ATP energy, oxygen or altering intracellular calcium levels causing an overall improvement in cardiac efficiency. (wikipedia.org)
  • cylindrical
  • Krogh model is a scientific model in the area mass transfer explaining concentration of molecular oxygen through a cylindrical capillary tube as a function of a changing position over the capillary tube's length. (wikipedia.org)
  • aerobic
  • Under anoxic conditions, the predominant double-base lesion is a species in which C8 of guanine is linked to the 5-methyl group of an adjacent 3'-thymine (G[8,5- Me]T). Most of these oxygen-derived species are produced at a low level by normal aerobic metabolism. (wikipedia.org)
  • Physical exercises are generally grouped into three types, depending on the overall effect they have on the human body: Aerobic exercise is any physical activity that uses large muscle groups and causes the body to use more oxygen than it would while resting. (wikipedia.org)
  • function
  • The transgenic hearts showed significantly higher myocardial contractile function, as indicated by increased maximal rates of pressure development for contraction (+dP/dt) and relaxation (-dP/dt), together with shortening of the normalized time to peak pressure and time to half relaxation. (ahajournals.org)
  • Stimulation of the A1 receptor has a myocardial depressant effect by decreasing the conduction of electrical impulses and suppressing pacemaker cell function, resulting in a decrease in heart rate. (wikipedia.org)
  • readily
  • This is because oxygen molecules do not readily dissolve in water, and as T. carnifex is an immobile animal, extracting oxygen from water is difficult. (wikipedia.org)
  • lower
  • A quasi-congenic QTL introgression strain carrying a low alcohol consumption gene from BALB/c has lower voluntary alcohol consumption than C57BL/6, with 96% of loci in common (Vadasz et al, 1996). (spotidoc.com)
