What are the three medications used in the Bradycardia algorithm?

What is the goal of bradycardia therapy?
The goal of therapy for bradycardia or tachycardia is to rapidly identify and treat patients who are hemodynamically unstable. Pacing or drugs, or both, may be used to control symptomatic bradycardia. Cardioversion or drugs, or both, may be used to control symptomatic tachycardia.
How to treat bradycardia?
Initial treatment of any patient with bradycardia should focus on support of airway and breathing (Box 2). Provide supplementary oxygen, place the patient on a monitor, evaluate blood pressure and oxyhemoglobin saturation, and establish intravenous (IV) access. Obtain an ECG to better define the rhythm. While initiating treatment, evaluate the clinical status of the patient and identify potential reversible causes.
When to initiate transcutaneous pacing?
Be prepared to initiate transcutaneous pacing quickly in patients who do not respond to atropine (or second-line drugs if these do not delay definitive management). Pacing is also recommended for severely symptomatic patients, especially when the block is at or below the His-Purkinje level (ie, type II second-degree or third-degree AV block).
What is the bradycardia algorithm?
This bradycardia algorithm focuses on management of clinically significant brady cardia (ie, bradycardia that is inadequate for clinical condition).
What should be interpreted within the context of total patient assessment?
The ECG and rhythm information should be interpreted within the context of total patient assessment. Errors in diagnosis and treatment are likely to occur if ACLS providers base treatment decisions solely on rhythm interpretation and neglect clinical evaluation. Providers must evaluate the patient’s symptoms and clinical signs, including ventilation, oxygenation, heart rate, blood pressure, and level of consciousness, and look for signs of inadequate organ perfusion. These guidelines emphasize the importance of clinical evaluation and highlight principles of therapy with algorithms that have been refined and streamlined since the 2000 edition of the guidelines. 2 The principles of arrhythmia recognition and management in adults are as follows:
What is irregular narrow complex tachycardia?
An irregular narrow-complex or wide-complex tachycardia is most likely atrial fibrillation with an uncontrolled ventricular response. Other diagnostic possibilities include MAT. We recommend a 12-lead ECG and expert consultation if the patient is stable.
What is the first step in the management of tachycardia?
The first step in the management of any tachycardia is to determine if the patient’s condition is stable or unstable (Box 3). An unstable patient with wide-complex tachycardia is presumed to have VT, and immediate cardioversion is performed (Box 4 and see above).
What are the medications used in the Bradycardia algorithm?
There are 3 medications that are used in the Bradycardia ACLS Algorithm. They are atropine, dopamine (infusion), and epinephrine (infusion). More detailed ACLS pharmacology information is reviewed following this page.
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 dopamine infusion rate?
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.
Is bradycardia physiologic or physiologic?
A: Bradycardia may be physiologic in the hypothermic patient. This type of bradycardia is an appropriate response to the decreased metabolic rate that normally occurs with hypothermia.
Is it safe to use TCP for bradycardia?
In the case of bradycardia caused by MI, it would be safer to transcuta neous 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. This will help determine if atropine may exacerbate the patient’s condition.
Does atropine cause bradycardia?
First, atropine may be used for any type of block but may negatively affect outcomes if the bradycardia is being caused by myocardial infarction. This negative effect may occur because atropine increases the heart rate and myocardial oxygen demand.
What is the treatment for bradycardia with poor perfusion?
For the patient with symptomatic bradycardia with signs of poor perfusion, transcutaneous pacing is the treatment of choice.
What is the definition of Bradycardia?
Bradycardia definition. any rhythm disorder with a heart rate less than 60 beats per minute. symptomatic bradycardia. a heart rate less than 60/min that elicits signs and symptoms, but the heart rate will usually be less than 50/min. symptomatic bradycardia criteria. 1.) The heart rate is slow; 2.)
What is symptomatic bradycardia?
symptomatic bradycardia criteria. 1.) The heart rate is slow; 2.) The patient has symptoms, and 3.) The symptoms are due to the slow heart rate. Functional or relative bradycardia. when a patient may have a heart rate within normal sinus range, but the heart rate is insufficient for the patient's condition.
What is the goal of therapy?
goal of therapy is to improve the patient's clinical status rather than target an exact heart rate.
What is the TCP rate for atropine?
If atropine fails to alleviate symptomatic bradycardia, TCP should be initiated. TCP rate should use 60/min as a starting rate and adjust up or down based on the patient's clinical response. The dose for pacing should be set at 2mA (milliamperes) above the dose that produces observed capture.
Can you give atropine if you have bradycardia?
Yes- give atropine, if ineffective transcutaneous pacing and/or dopamine/epinephrine infusion. consider expert consultation or transvenous pacing if other efforts are ineffective. Transcutaneous Pacing (TCP) If atropine fails to alleviate symptomatic bradycardia, TCP should be initiated.
What is the dose of dopamine for bradycardia?
Dopamine: Second-line drug for symptomatic bradycardia when atropine is not effective. Dosage is 2-20 micrograms/kg/min infusion. Epinephrine: Can be used as an equal alternative to dopamine when atropine is not effective. Dosage is 2-10 micrograms/min. decision point for ACLS intervention in the bradycardia algorithm.
Is TCP contraindicated for hypothermia?
TCP is contraindicated in the patient with hypothermia and is not a recommended treatment for asystole. Bradycardia and Atropine. 0.5 mg IV every 3-5 minutes as needed, and the maximum total dosage that can be given is 3 mg. Use cautiously in: MI and Hypoxia. AVOID IN: Mobitz type II/Second degree block type 2.
When to place TCP electrodes?
place TCP electrodes in anticipation of clinical deterioration in pts with acute myocardial ischemia or infarction associated with following rhythms:

What to use for transcutaneous pacing?
prepare for transcutaneous pacing, consider atropine while preparing TCP, use epinephrine or dopamine while awaiting pacemaker or if pacing is ineffective.
Is there a response to atropine?
there is no response to atropine , atropine is unlikely to be effective or if IV access cannot be quickly established , the patient is severely symptomatic
Does the impulse generated in the SA node in the atrium propagate to the ventricles?
The impulse generated in the SA node in the atrium does not propagate to the ventricles and there is no apparent relationship between P waves and QRS complexes.
