Beta blockers (β-blockers or BBs) were invented and designed by Sir James Black‚ who was a Nobel Prize winning scientist. Black designed beta blockers to counteract stimulated adrenergic effects. He demonstrated that‚ by blocking the cardiac beta-receptors‚ these agents could cause inhibitory effects on the sinus node (chronotropic effect)‚ atrioventricular node (dromotropic effect)‚ and on myocardial contractility (inotropic effect).1 It is important to note that not all beta receptors (β-receptors)

Beta adrenergic receptor antagonists (Beta Blockers) For several years‚ CHF treatment involved drugs with sympathomimetic properties. This was based on the belief that heart failure is fundamentally a disorder of reduced stroke volume and cardiac output. Long-term use of sympathomimetics was expected to improve clinical outcomes based on relief obtained from short term use of dopamine and dobutamine. Under this model‚ the use of beta adrenergic receptor antagonists was believed to be counterintuitive;

Ashlyn Blocker was born with a condition called congenital insensitivity which leaves her feeling absolutely no pain. The disease is caused by two found gene mutations which cut off the pain signals that are sent to Ashlyn’s brain. Her doctor’s name is Dr. Roland Staud who is a pain expert and professor in the University of Florida‘s college of medicine. There are only 20 documented cases of insensitivity to pain in our entire country which makes Ashlyn’s health issue “one in six billion”. Ashlyn

Beta blockers are another type of medication; they reduce the workload on your heart and open your blood vessels‚ causing your heart to beat slower and with less force. Beta blockers include: acebutolol (Sectral)‚

Neuromuscular blockers work by impeding motor nerve impulses from passing to the skeletal muscles. The purpose of blocking these passes is to make the muscles weak or paralyzed in surgery. Neuromuscular blockers can be used in many surgical procedures‚ like inserting an endotracheal tube‚ by relaxing the jaw muscles. They are also useful for relaxing the diaphragm and intercostal muscles (responsible for respirations) so that the patient can be manually ventilated. Neuromuscular blockers also aid in

bloomberg beta interpretation Beta definition A measure of an asset’s risk in relation to the market (for example‚ the S&P500) or to an alternative benchmark or factors. Roughly speaking‚ a security with a beta of 1.5‚ say‚ will move 50% more than the market. So if the market goes up by 20% the security’s price will go up by 30%. According to asset pricing theory‚ beta represents that part of the risk of the security called systematic risk that cannot be diversified away. When using beta‚ there are
