Beta blockers are used in the prophylaxis of exertional angina by reducing the work the heart is allowed to perform below the level that would provoke an angina attack.

Beta blockers may slow the heart rate to a dangerous level if prescribed together with calcium channel blocker type medications.

Beta blockers such as propranolol ( Inderal, Inderal LA, Innopran XL ) can help to control the heart rate, and intravenous steroids may be used to help support the circulation.

Beta blockers, typically used to treat high blood pressure, are a class of drugs that offset this effect, reducing rapid pulse associated with the sensation of palpitations, and decreasing tremor and anxiety.

Beta blockers ( e. g., carvedilol, propranolol, atenolol ) have a large body of evidence in morbidity and mortality benefits ( fewer symptoms, less disability and longer life ) and short-acting nitroglycerin medications have been used since 1879 for symptomatic relief of angina.

Beta blockers that target the beta-1 receptor are called cardio selective because beta-1 is responsible for increasing heart rate ; hence a beta blocker will slow the heart rate.

Beta blockers ( sometimes written as β-blockers ) or beta-adrenergic blocking agents, beta-adrenergic antagonists, beta-adrenoreceptor antagonists or beta antagonists, are a class of drugs used for various indications.

Beta blockers block the action of endogenous catecholamines epinephrine ( adrenaline ) and norepinephrine ( noradrenaline ) in particular, on β-adrenergic receptors, part of the sympathetic nervous system which mediates the fight-or-flight response.

Beta blockers are primarily known for their reductive effect on heart rate, although this is not the only mechanism of action of importance in congestive heart failure.

Beta blockers, in addition to their sympatholytic B1 activity in the heart, influence the renin / angiotensin system at the kidneys.

Beta blockers cause a decrease in renin secretion, which in turn reduces the heart oxygen demand by lowering extracellular volume and increasing the oxygen-carrying capacity of blood.

Beta blockers ' sympatholytic activities reduce heart rate, thereby increasing the ejection fraction of the heart despite an initial reduction in ejection fraction.

Beta blockers are inexpensive, said to be relatively safe and, on one hand, seem to improve musicians ' performances on a technical level, while some say the performances may be perceived as " soulless and inauthentic ".

Beta blockers are banned by the International Olympic Committee.

Beta blockers must not be used in the treatment of cocaine, amphetamine, or other alpha-adrenergic stimulant overdose.

Beta blockers are contraindicated in patients with asthma as stated in the BNF 2011.

Beta blockers inhibit these normal epinephrine and norepinephrine-mediated sympathetic actions, but have minimal effect on resting subjects.

Beta blockers are readily titrated to optimal rate control in many pathologic states.

Beta blockers decrease nocturnal melatonin release, perhaps partly accounting for sleep disturbances caused by some agents.

** Beta blockers

Beta blockers and other pharmacological agents that slow electrical conduction through the AV pathway ( such as digoxin ) should be avoided, because they can exacerbate the syndrome by blocking the heart's normal electrical pathway ( therefore favoring transmission through the pre-excitation pathway ).

Beta blockers can cause hypotension both by slowing the heart rate and by decreasing the pumping ability of the heart muscle.

Beta blockers never should be used alone to treat clonidine withdrawal as alpha vasoconstriction would still continue.

* 1989-Millsaps becomes the first school in Mississippi to have a chapter of the Phi Beta Kappa honor society.

The NCAC is respected for the academic strength of its member institutions — all of which have Phi Beta Kappa chapters.

Beta Israel black Jews have lived in Ethiopia for centuries, disconnected from the rest of Judaism ; their existence has given some impetus to Rastafari, as they believe it validates their assertion that Ethiopia is Zion.

Warm silica-rich dust and abundant SiO gas, products of high velocity (> 10 km / s ) impacts between rocky bodies, have been detected around the nearby ( 29 pc distant ) young (~ 12 My old ) Beta Pic Moving Group star HD172555 by the Spitzer Space Telescope.

If Gudit did not belong to one of the Sidamo peoples, then some scholars, based on the traditions that Gudit was Jewish, propose that she was of the Agaw people, who historically have been numerous in Lasta, and a number of whom ( known as the Beta Israel ), have professed an Israelite pre-Ezra Judaism since ancient times.

In this section we show that the order statistics of the uniform distribution on the unit interval have marginal distributions belonging to the Beta distribution family.

Two sororites, Kappa Kappa Gamma and Kappa Delta, and two fraternities, Beta Theta Pi and Sigma Phi Epsilon, have locked floors in Hamlin Hall.

Phi Beta Kappa presidents have spoken at Phi Theta Kappa conventions, and the two societies have formed joint programs to encourage community and junior college graduates to advance to four-year institutions.

Gas-poor disks of circumstellar dust have been found around many nearby stars — most of which have ages in the range of ~ 10 million years ( e. g. Beta Pictoris, 51 Ophiuchi ) to billions of years ( e. g. Tau Ceti ).

With Excel as an example, using the GammaLn and ( cumulative ) Beta distribution functions, we have:

Beta Cephei variables do not have wide ranges in magnitude, nor do they have periods longer than a few hours.

While VHS and Beta tapes have a break-off tab to protect recordings from erasure ( as in audio Compact Cassettes and, once broken, the cavity left by the missing tab must be covered or filled before the tape can be reused ), VCCs employ a more elegant solution: a switch on the tape edge can be turned to red to protect the recordings, and back to black / brown ( depending on the colour of the cassette housing ) to re-record.

This would have offered the format another advantage over VHS / Beta as the hifi track would be independent of the visuals, and so could be re-recorded or dubbed as became possible later with Video8.

Many are elected to membership in Phi Beta Kappa, and have received awards, including Brooklyn College ’ s Tow Travel Fellowship and Furman Travel Fellowship for undergraduate international study and research, and the nationally competitive Beinecke Fellowship and Mellon Humanities Fellowship for graduate study.

As of the 2010-2011 school year, Alpha Phi Alpha, Alpha Kappa Alpha, Delta Sigma Theta, Kappa Alpha Psi, Omega Psi Phi, Phi Beta Sigma, and Zeta Phi Beta have chapters at OSU.

As Alex continues his training under Grig's tutelage, Beta continues to have difficulties in maintaining his impersonation of Alex -- particularly with Maggie.
