What else can I help you with?
What effect does atropine have on heart rate?
Ventricular fibrillation, and supraventricular or ventricular tachycardia.
What is the drug injected into the heart to protect from chemical agents?
There are two drugs you get to carry around with you to keep you from dying in a chemical agent attack. One's atropine--one of the things nerve gas does to you is slows down your heart, and atropine speeds it up. The other is "2 Pam Chloride" which neutralizes the nerve agent.
Drugs that increase heart rate blood pressure and breathing rate are?
Atropine increases the heart rate by increasing the sympathetic nerve stimulation while propanalol decreases the heart rate by decreasing the parasympathetic nerve stimulation.
How does slow tempo music effect a persons heart rate?
Slow tempo will decrease your heart rate because it might put you to sleep and that would rest your heart rate.
Why won't CPR restart the heart?
In order to restart the heart, from asystole, drug therapy is usually required; such as epinephrine, vasopressin, or atropine. A shock may still be applied. If the heart is in arrhythmia, it will require a shock to reset the heart. CPR will not bring the heart back to a normal rhythm, or restart the heart. CPR will circulate oxygenated blood until help arrives to administer shocks or drug therapy.
What effect does atropine have on heart rate?
Ventricular fibrillation, and supraventricular or ventricular tachycardia.
Why does atropine cause tachycardia?
Check out the atropine page at wikipedia.org for your answer.
What is the effect of atropine plus acetylcholine on frog heart?
ACh will decrease heart rate/contractile strength, etc. Atropine is a muscarinic ACh receptor (mAChR) antagonist, so blocks the effects of ACh. Adding both together will result in a weak action of ACh that tails off as all the mAChRs become blocked by Atropine.
Why would a doctor prescribe atropine?
atropine
Will pilocarpine reverse effect of atropine?
yes
What does atropine do the heart?
It blocks the vegus nerve/ parasympathetic heart. This means that the heart rate can not be slowed down.
Why physostigmine is the antidote for atropine?
Physostigmine inhibit AchE (the enzyme that hadrolyse Ach), so Ach accumulate at synaptic cleft and banish the effect of atropine
Atropine sulfate preoperatively?
atropine sulfate is used as an antidote of anticholinesterase meds administered on patients with myasthenia gravis. Atropine sulfate should be also made available when performing the Tensilon Test to reverse the effect of Edrophonium injection.
Why does atropine effect histamine receptors?
It doesn't atropine only acts on muscarinic receptors (it's a competitive antagonist here for ACh), but histamine acts on different receptors (histamine receptors). There is no direct interaction between atropine and histamine receptors
Why can't you give atropine in complete heart block?
Atropine is an anticholinergic medication that increases heart rate by blocking vagal effects on the heart. In complete heart block (third-degree AV block), the electrical signals do not pass from the atria to the ventricles, leading to dissociation between the two. Since atropine primarily affects the atrial conduction and the blockage is at the AV node, it is ineffective in restoring normal heart rhythm or rate. Therefore, it cannot be used to treat complete heart block, and other interventions like pacing are necessary.
Why atropine has no effect on blood pressure?
The muscarinic receptors in the vasculature are not inneravated by the parasympathetic nervous system. Therefore, atropine binds to these receptors, but causes no response since it is a pure muscarinic antagonist.
Why does lomotil has atropine?
Lomotil contains atropine primarily to discourage misuse and abuse of the medication. Atropine is included in a small dose to counteract the potential for high-dose diphenoxylate (the primary active ingredient) to induce euphoria. By incorporating atropine, the formulation aims to deter individuals from using the medication recreationally, as higher doses can lead to unpleasant side effects associated with atropine, such as dry mouth and increased heart rate.
