For the patient without any immediately reversible causes, who demonstrates signs or symptoms of poor perfusion due to a bradyarrhythmia such as a third-degree AV block, the ACLS Adult Bradycardia Algorithm recommends administering atropine
Atropine
This medication is used before eye examinations and to treat certain eye conditions.

When to give atropine ACLS?
- Antisialagogue/anti-vagal: 0.5 mg to 1 mg every 1 to 2 hours
- Organophosphate or muscarinic poisoning: 2 mg to 3 mg every 20 to 30 minutes (may require doses up to 20 mg, titrate to effect for secretion control)
- Bradycardia: 1 mg every 3 to 5 minutes (3 mg max), repeat until obtaining desired heart rate, most effective for sinus and AV nodal disease.
When to treat bradycardia ACLS?
- If atropine does not relieve the bradycardia, continue evaluating the patient to determine the underlying cause and consider transcutaneous pacing
- Consider an IV/IO dopamine infusion at 2-10 mcg/kg/minute
- Consider an IV/IO epinephrine infusion at 2-10 mcg/minute.

In which situation is bradycardia require treatment?
Patients with imminent heart failure or unstable patients with bradycardia need immediate treatment. The drug of choice is usually atropine 0.5–1.0 mg given intravenously at intervals of 3 to 5 minutes, up to a dose of 0.04 mg/kg. Other emergency drugs that may be given include adrenaline (epinephrine) and dopamine.
When should you start CPR on bradycardia?
Start CPR if HR <60/min despite oxygenation and ventilation.
Does bradycardia need to be treated?
In most cases, bradycardia in healthy, well-trained athletes does not need to be treated. In fact, in most people, bradycardia does not require treatment unless patients have symptoms that are clearly due to a slow heartbeat.
How is ACLS bradycardia treated?
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 priority intervention for symptomatic bradycardia?
The initial interventions within the bradycardia algorithm for all infants and children with symptomatic bradycardia include the following: Identify and treat the underlying cause. Provide oxygen. Attach a cardiac monitor for rhythm identification.
Is bradycardia an emergency?
If you have bradycardia, your heart beats fewer than 60 times a minute. Bradycardia can be a serious problem if the heart rate is very slow and the heart can't pump enough oxygen-rich blood to the body. If this happens, you may feel dizzy, very tired or weak, and short of breath.
What is a dangerously low heart rate?
When the heart does not operate as it is supposed to and develops an abnormally slow heart rate that is less than 60 beats per minute, the condition is known as bradycardia. Bradycardia can be life threatening if the heart is unable to maintain a rate that pumps enough oxygen-rich blood throughout the body.
What is a first line treatment for a patient with unstable 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.
What is considered bradycardia?
Bradycardia is a heart rate that's too slow. What's considered too slow can depend on your age and physical condition. Elderly people, for example, are more prone to bradycardia. In general, for adults, a resting heart rate of fewer than 60 beats per minute (BPM) qualifies as bradycardia.
At what heart rate do you give atropine?
Atropine is the first-line therapy (Class IIa) for symptomatic bradycardia in the absence of reversible causes. Treatments for bradydysrhythmias are indicated when there is a structural disease of the infra-nodal system or if the heart rate is less than 50 beats/min with unstable vital signs.
When do you give atropine vs epinephrine?
Epinephrine provides a greater amount of hemodynamic support. Patients dying with bradycardia aren't truly dying from bradycardia itself, but rather from cardiogenic shock (low cardiac output). Atropine offers these patients an increased heart rate, nothing more.
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.
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).
Is it safe to use transcutaneous pacing for Mobitz II?
Any time you increase HR, the diastolic filling time is reduced and this reduces the coronary perfusion. Transcutaneous pacing should be the first line action for symptomatic Mobitz II and symptomatic complete heart block. It is very safe & less painful than in previous times due to technological improvements.
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 are the symptoms of bradycardia?
5. Common bradycardia symptoms include: syncope. presyncope. transient dizziness or lightheadedness. fatigue. dyspnea on exertion. heart failure symptoms.
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
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 are the two most common types of bradycardia that require emergency intervention?
Bradycardia Algorithm Diagram. The two most common types of bradycardia that require emergency intervention are 2nd° heart block type II and 3rd° heart block. Both of these bradyarrhythmias can lead to decreased blood perfusion. These bradyarrhythmias should be treated using the bradycardia algorithm.
What is the best treatment for bradyarrhythmia?
These bradyarrhythmias should be treated using the bradycardia algorithm. The two most important interventions for the treatment of symptomatic bradycardia are the administration of atropine and the initiation of transcutaneous pacing.
