4 9 However, these data also demonstrate an association between increasing heart rate and an increased likelihood of AF progression.
For example, cardiac output is augmented by increasing heart rate.
Like amphetamine or ephedrine, clenbuterol acts as a stimulant, increasing heart rate.
In the excitement stage, the body prepares for sexual activity by tensing muscles and increasing heart rate and blood pressure.
In the excitement stage, the body prepares for sexual activity by tensing muscles and increasing heart rate.
Pressure receptors, or baroreceptors, in the walls of the aorta and carotid arteries trigger physiological reflexes to protect the central circulation, increasing heart rate to boost cardiac output and constricting small blood vessels to direct blood flow to essential organs.
These substances prepare the body to react to immediate danger by increasing heart rate, increasing oxygen delivery to the brain, dilating blood vessels in skeletal muscles, and increasing blood glucose levels.
Inotropic support could hypothetically exacerbate stress-induced diastolic dysfunction by increasing heart rate and/or myocardial oxygen demand.
Before administration of these drugs, there was no significant increase in LV contractility and relaxation by increasing heart rate.
