Beta 2 is generally associated with smooth muscle relaxation (as in the bronchioles in the lungs) and dilation of blood vessels to skeletal muscles. Beta 1 is responsible for the increase in heart rate. Although beta 2 agonists like Albuterol are meant to trigger only the beta 2 in the lung, you may see a little cross reaction resulting in an increased heart rate. So, in a nut shell...no.

Yes, it can increase the heart rate. However this is an unlikely, but serious side effect.

slows it down
beta blockers lower heart rate and they blunt the HR response to exercise.
Yes they slow the heart down a little depending on the dosage you take.

Why you use beta blocker in heart failure?

Beta blockers act to reduce the workload on the heart by reducing the heart rate and relaxing the aterial walls, decreasing peripheral resistance.


What is a beta blocker and what does it do?

Beta blockers are a class of drugs that target the beta receptor. Beta receptors are found on cells of the heart muscles, smooth muscles, airways, arteries, kidneys, and other tissues that are part of the sympathetic nervous system. These blockers interfere with the binding of epinephrine to the beta site and weaken the effects of stress hormones. They slow down the heart rate and are used for high blood pressure, mostly.


After stopping beta blockers how long before heart rate returns to normal?

It depends (mostly) on which beta-blocker you were on, but it should range from 24 hours to a week.

How do you reduce heart beats?

Relaxation exercises (slow and deep breathing) and meditation are voluntary acts that can reduce heart rate (pulse). Medications such as cholinergics, reversible acetylcholinesterase inhibitors, beta blockers (a.k.a. beta-adrenergic antagonists), opiates, and benzodiazepines can also reduce heart rate.


What can you take to slow down your heart rate?

If your question is "Is there a medication that slows your heart rate?" then the answer is yes. There are several, but some of the most common are beta blockers (atenolol), benzodiazepines (Xanax), sedatives, and barbiturates, just to name a few. Caution should be exercised. If you take too much of any of these drugs your heart rate could slow down too much and cause permanent damage or even stop and result in death.
