Is isoproterenol an Inodilator?
It is an inotropic vasodilator at therapeutic doses and should be used with caution in patients with borderline hypotension, because it occasionally reduces BP further. Isoproterenol is a potent beta-agonist that causes profound tachycardia with vasodilation and is contraindicated in heart failure.

What is atropine used for?
Atropine is a prescription medicine used to treat the symptoms of low heart rate (bradycardia), reduce salivation and bronchial secretions before surgery or as an antidote for overdose of cholinergic drugs or mushroom poisoning. Atropine may be used alone or with other medications.
What is Metaraminol used for?
ARAMINE (metaraminol) is indicated for prevention and treatment of the acute hypotensive state occurring with spinal anesthesia. It is also indicated as adjunctive treatment of hypotension due to hemorrhage, reactions to medications, surgical complications, and shock associated with brain damage due to trauma or tumor.
Which drug is also known as Inodilator?
Levosimendan is an inodilator developed for treatment of acute heart failure. It was shown to enhance cardiac contractility, and to exert a vasodilatory effect in all vascular beds.Mar 8, 2017
Is digoxin an Inodilator?
Cardiac glycosides (eg, digitalis alkaloids) were the first inotropic drugs administered for the therapy of HF. Digoxin was shown to increase Ca 2+ influx into the cytoplasm by interfering the sarcolemmal sodium–calcium exchange process because of its inhibitory action on the sodium–potassium ATPase (Na +-K + ATPase).
What is the drug Levophed?
Levophed (norepinephrine bitartrate) is a vasoconstrictor, similar to adrenaline, used to treat life-threatening low blood pressure (hypotension) that can occur with certain medical conditions or surgical procedures. Levophed is often used during or after CPR (cardio-pulmonary resuscitation).
What are Catecholamines?
Catecholamines include adrenaline, noradrenaline and dopamine. They are physiologically important neurotransmitters, as part of the sympathetic and central nervous systems. Catecholamines act on both the alpha and beta adrenergic receptors. Catecholamines are released in times of stress.

What is the first line of medication for bradycardia?
Atropine . Atropine is the first line medication for the treatment of bradycardia. The administration of atropine typically causes an increase in heart rate. This increase in the heart rate occurs when atropine blocks the effects of the vagus nerve on the heart. When the vagus nerve is blocked, the SA node increases its rate ...
What are the drugs used in the bradycardia algorithm?
ACLS Drugs for Bradycardia (2020) There are three medications used in the bradycardia algorithm: atropine, epinephrine, and dopamine. Read about each drug and its use within the bradycardia algorithm below. When symptomatic bradycardia occurs, the primary objective is to identify and treat the cause of the problem.
How much atropine should I take for a heart block?
The dosing for Atropine is 1 mg IV every 3-5 minutes as needed, and the maximum total dosage for administration is 3 mg. Atropine should be avoided with bradycardia caused by hypothermia and, in most cases, it will not be effective for Mobitz type II/Second-degree block type 2 or complete heart block.
How does atropine work?
First, let’s look at atropine and how it works. Atropine increases the firing of the sinoatrial node (atria) and conduction through the atrioventricular node (AV) of the heart by blocking the action of the vagus nerve.
What is the primary objective of atropine?
When symptomatic bradycardia occurs, the primary objective is to identify and treat the cause of the problem. Medications are indicated if symptomatic bradycardia cannot be corrected by treating an underlying cause or if the cause cannot be determined. 2020 AHA Update The single-dose administration of atropine was increased from 0.5 mg to 1 mg.
Does Mobitz II cause heart block?
Caution with Atropine. It is important to note that Mobitz II and complete heart block may be associated with acute myocardial ischemia. If atropine is used when there is ongoing myocardial ischemia this may worsen myocardial ischemia because of an increase in oxygen consumption.
Can atropine be used for bradycardia?
They are both used as infusions in the bradycardia algorithm if atropine is ineffective. ACLS guidelines state that if bradycardia is unresponsive to atropine, an equally effective alternative to transcutaneous pacing is the use of an IV infusion of the beta-adrenergic agonists (dopamine or epinephrine).
Bradycardia and cardiac output
Bradycardia is a broad term that indicates a heart rate under 60 beats/minute. It encompasses the following arrhythmias:
Cardiac drugs that pose a risk
Cardiovascular medications that may trigger bradycardia include the following:
Noncardiac drugs that pose a risk
Certain drugs given for noncardiac conditions can pose similar risks for developing bradycardia, including:
Teach caution
Any one of Johnson’s medications—or a combination—could’ve decreased his heart rate and caused his syncope. To protect a patient who’s taking a drug that could cause bradycardia, staff should teach him the signs and symptoms and tell him how to monitor his pulse rate and when to call the primary care provider to report a problem.
What determines cardiac output?
Cardiac output, the amount of blood pumped from the heart each minute (average 4-8 l/min), is the product of stroke volume times heart rate. Stroke volume is the amount of blood pumped from the left ventricle with each beat (average 70 ml). It’s influenced by afterload, preload, and contractility.
What is the treatment for neurogenic bradycardia?
If it is possible to stop the attack with medicines, then use isadrine, alupent, atropine. Some patients have intolerance to these drugs, then ephedrine is used.
What is the procedure for bradycardia?
In bradycardia, a person may lose consciousness and then it is necessary to carry out artificial respiration and indirect heart massage until the arrival of ambulance. Frequently arising arrhythmia requires medication that is prescribed by the cardiologist. If it does not produce results, then the pacemaker is implanted.
How to treat sinus bradycardia?
Actions such as taking a warm bath, brewing strong coffee or tea, performing special physical exercises (walking down the stairs, running or walking in the open air) can help to reduce the manifestations of the disease.
Which is more effective, isoproterenol or atropine?
If the slowing of the rhythm is extremely pronounced, then drugs such as atropine, alupent, isadrine, isoproterenol are used. Ephedrine is sometimes more effective, which is especially shown to the patient who does not tolerate atropine and isadrin.
What substances help remove potassium from the body?
Some of them help remove potassium from the body (diuretics, cation exchange resins, aldosterone-containing substances). The action of others is aimed at stimulating the transfer of potassium from the intercellular fluid to the middle of cells (glucose with insulin, calcium chloride, sodium bicarbonate).
What to do if your heart rate drops below 40?
The disease may occur with a poorly defined clinic and then no drugs are used. If the slowing of the rhythm is extremely pronounced, that is, the heart rate has dropped below 40 beats / min, then urgent measures should be taken. First of all an ambulance is called, then the patient is placed on a horizontal surface and raises his legs. If necessary, actions are performed on the return of consciousness or a cardiopulmonary resuscitation is performed. In the conditions of the hospital, preparations are introduced from the group of cholinolytics, which help to increase the heart rate and improve the well-being of the patient.
What are the symptoms of ischemic bradycardia?
Drug treatment is performed in those cases where the following symptoms are observed: an abnormal condition, a reduced blood pressure, long or hard stopping attacks of a slowed heartbeat, a sharp intolerance to sick signs of the disease.
