How much epinephrine do you give for bradycardia?
IV infusion for bradycardia: 1mg epinephrine is mixed with 500ml of NS or D5W. The infusion should run at 2-10 mcg/min and titrate to the patient’s response. Dopamine 400 mg is mixed with 250 ml NS. Begin the dopamine infusion at 2 to 20 mcg/kg/min and titrate to the patient’s response.
What is the role of epinephrine and dopamine in bradycardia?
Epinephrine and dopamine are second-line drugs for symptomatic bradycardia. They are both used as infusions in the bradycardia algorithm if atropine is ineffective.
What is the recommended dopamine infusion rate for bradycardia?
Also, the dopamine infusion rate for chemical pacing was changed to 5-20 mcg/kg/min. The previous rate from the 2015 guidelines was 2-20 mcg/kg/min. Atropine is the first line medication for the treatment of bradycardia. The administration of atropine typically causes an increase in heart rate.
How much epinephrine do you put in an IV infusion?
Epinephrine dosing: 2-10 mcg/min infusion (it is safe to use a proximal peripheral line initially with frequent limb checks) If atropine, dopamine, epinephrine and pacing are ineffective, and the cause of bradycardia is unclear, consider IV calcium chloride or calcium gluconate.

When a patient is evaluated for symptomatic bradycardia, an in-depth history and physical is
When a patient is evaluated for symptomatic bradycardia, an in-depth history and physical is important, along with the identification of possible reversible causes. The following is a list of conditions associated with bradycardia and conduction disorders: 11
What is bradycardia heart rate?
What is bradycardia? The National Institutes of Health defines bradycardia* as a heart rate <60 bpm in adults other than well-trained athletes. 9 The determination on whether or not treatment is necessary for bradycardic events is generally based on the presence of bradycardia symptoms. The clinical manifestations of bradycardia can vary widely from insidious symptoms to episodes of frank syncope. 5
What percentage of patients with sleep apnea have sinus bradycardia?
The prevalence of sinus bradycardia in patients with sleep apnea can be as high as 40%, with episodes of second- or third-degree AV block in up to 13% of patients. 8
How much atropine is given?
Atropine 0.5 mg intravenous (IV) is given up to a total of 3 mg. 1 Atropine sulfate acts by reversing the cholinergic-mediated decreases in the heart rate and AV node conduction. 1. If atropine is ineffective, two treatment pathways are available.
What are the symptoms of bradycardia?
5. Common bradycardia symptoms include: syncope. presyncope. transient dizziness or lightheadedness. fatigue. dyspnea on exertion. heart failure symptoms.
What pharmacologic choice is given for heart pacing?
The two pharmacologic choices are dopamine 2 to 20 mcg/kg/min and/or epinephrine 2 to 10 mcg/min. 1.
Can exercise be used to diagnose ischemia?
Exercise Testing. Although not routinely recommended for assessment of ischemia, exercise testing can be considered in patients with symptoms temporally related to exercise, asymptomatic second-degree AV block, or for suspected chronotropic incompetence. 11.
What is the best drug for symptomatic bradycardia?
Atropine: The first drug of choice for symptomatic bradycardia. The dose in the bradycardia ACLS algorithm is 1 mg IV push and may repeat every 3-5 minutes up to a total dose of 3 mg. Dopamine: Second-line drug for symptomatic bradycardia when atropine is not effective. Dosage is 5-20 micrograms/kg/min infusion.
What is the best treatment for bradycardia?
2015 AHA Update: For symptomatic bradycardia or unstable bradycardia IV infusion a chronotropic agent (dopamine & epinephrine) is now recommended as an equally effective alternative to external pacing when atropine is ineffective. Atropine: The first drug of choice for symptomatic bradycardia.
What lead ECG should I use for MI?
You should use the 12 lead ECG to help determine MI. This will help determine if atropine may exacerbate the patient’s condition. If the patient has severe symptoms, you should not delay transcutaneous pacing (TCP). You will usually have time to try atropine as you prepare for TCP.
What is TCP in medical terms?
Transcutaneous pacing (TCP) Preparation for TCP takes place as atropine is being given. If atropine fails to alleviate symptomatic bradycardia, TCP is initiated. Ideally, the patient receives sedation prior to pacing, but if the patient is deteriorating rapidly, it may be necessary to start TCP prior to sedation.
What is the decision point for ACLS intervention in the bradycardia algorithm?
The decision point for ACLS intervention in the bradycardia algorithm is determination of adequate perfusion. For the patient with adequate perfusion, observe and monitor the patient. If the patient has poor perfusion, preparation for transcutaneous pacing should be initiated, and an assessment of contributing causes (H’s and T’s) should be carried out.
What is the difference between bradycardia and bradycardia?
Symptomatic Bradycardia. Bradycardia is defined as any rhythm disorder with a heart rate less than 60 beats per minute. (Usually less than 60) Symptomatic bradycardia, however, is defined as a heart rate less than 60/min that elicits signs and symptoms, but the heart rate is typically less than 50/min.
Why is atropine bad for heart rate?
This negative effect may occur because atropine increases the heart rate and myocardial oxygen demand. In the case of bradycardia caused by MI, it would be safer to transcutaneous pace (TCP) at a rate of 60 and move toward some type of cardiac intervention. You should use the 12 lead ECG to help determine MI.
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).
What is the primary goal of cardiac ischemia?
Cardiac ischemia – primary goal is cardiac catheterization/revascularization; transfer patient to cath lab ASAP, consider bradycardia medications/transcutaneous pacing only as a bridge to catheterization; use minimal doses of dopamine and/or epinephrine as either drug may exacerbate cardiac ischemia
Can Digoxin cause bradyarrhythmia?
Digoxin toxicity can cause almost any bradyarrhythmia from junctional bradycardia to complete heart block. One clue to differentiate calcium blocker toxicity from B-blocker toxicity is that Ca-blocker poisoning tends to cause hyperglycemia vs B-blocker poisoning tends to be normoglycemic or hypoglycemic.
Is ketamine a good analgesic for transcutaneous pacing?
Consider ketamine as your first line analgesic for the patient undergoing transcutaneous pacing as it is least likely to cause hypotension, may help increase the heart rate and it helps maintains respirations
Does atropine increase heart rate?
At higher doses, atropine increases heart rate by blocking M2 acetylcholine receptors on the myocardium itself. Atropine-induced bradycardia may be especially difficult to manage in patients who are morbidly obese or post cardiac transplantation.
Does atropine fire up the SA node?
Atropine essentially fires up the SA node by poisoning the vagus nerve; it therefore is effective only if the distal conduction system is conducting normally. Overall, only 28% of patients with bradycardia have been shown to respond to atropine.
Does pacing cause bradycardia?
Hypothermia – warming measures usually preclude the need for bradycardia medications/pacing; rewarming is the first line treatment for bradycardia in patients with severe hypothermia; pacing may precipitate ventricular fibrillation in severely hypothermic patients.
Can a permanent pacemaker be placed in the ED?
Indications for permanent pacemaker for bradycardia and bradydysrhythmias. The decision to place a permanent pacemaker is almost never made in the ED; nonetheless it is important for the EM physician to be aware of which patients are likely to require permanent pacemaker at a later date.
