1. What is the drug of first choice for symptomatic bradycardia?





2. Which ECG rhythm is commonly associated with bradycardia?





3. What is generally considered the most important and clinically significant degree of block?





4. Which drugs are involved in the Bradycardia Algorithm?





5. Bradyarrhythmia is defined as:





6. Symptomatic bradycardia exists when_________.





7. Symptoms of bradycardia can include chest discomfort or pain, shortness of breath, decreased level of consciousness, weakness, fatigue, lightheadedness, dizziness, and presyncope or syncope.



8. Signs of symptomatic bradycardia include hypotension, orthostatic hypotension, diaphoresis, pulmonary congestion, frequent PVC's or VT.



9. The primary decision point in the bradycardia algorithm is the determination of:





10. After it is determined that the patient does not have adequate perfusion your first step is to:







  1. 2010 AHA ACLS Provider Manual pg. 110 Box 4: “Give Atropine as first-line treatment.”
  2. 2010 AHA ACLS Provider Manual pg. 105 identifies all of the major ECG rhythms associated with bradycardia.
  3. 2010 AHA ACLS Provider Manual pg. 105: “Complete block is generally the most important and clinically significant degree of block.” It is also the most likely block to cause cardiovascular collapse.
  4. 2010 AHA ACLS Provider Manual pg. 106: Under the heading “Drugs for Bradycardia.”
  5. 2010 AHA ACLS Provider Manual pg. 107
  6. 2010 AHA ACLS Provider Manual pg. 107 “A symptomatic bradycardia exists clinically when these 3 criteria are present:”)
  7. 2010 AHA ACLS Provider Manual pg. 107
  8. 2010 AHA ACLS Provider Manual pg. 107: All listed are included as signs of bradycardia. Note particularly that VT and PVC’s occur as bradycardia related escape rhythms.
  9. 2010 AHA ACLS Manual pg. 108: Adequate perfusion is the primary decision point for determining if use of the bradycardia algorithm is necessary.
  10. 2010 AHA ACLS Manual pg. 109: Per the Bradycardia algorithm, the first step after determining inadequate perfusion is to give atropine.

    Dear Jeff,
    Is VT a sign of bradycardia as stated in one of the questions?

    In regards to question #5, Bradyarrhythmia is any rhythm disorder with a heart rate less than 60 beats per minute. I know that this has been the standard of care for as long as I can remember, however in my 2010 Handbook of Emergency Cardiovascular Care for Healthcare Providers that I am using to study, it states on page 9 under the Bradycardia with a Pulse Algorithm, that
    “Heart rate typically <50/min if bradyarrhythmia."

    So, is a rhythm considered a brady rhythm with a heart rate below 60, or below 50??
    I do not have the new ACLS Study Guide book for further reference. Thank you.

      A rhythm is considered bradycardia (brady rhythm) if the rate is less than 60. The part about 50 bpm simply means that if the rate is the cause of symptoms, the rate will generally be < 50 bpm.

    Question 6: The question is about “Symptomatic” Brady and on page 107, the answer seems to be “S/S due to the slow heart rate”; the answer accepted here is about bradycardia that is not symptomatic. Could I perhaps get clarification?

      Question #6 reads: “Symptomatic bradycardia exists when_________.” The answer is all of the above so the full statement would read: “Symptomatic bradycardia exists when the heart rate is slow, there are symptoms present, and the symptoms are related to the slow heart rate.” Essentially, this is the definition of symptomatic bradycardia. Without these three things, you have something other than symptomatic bradycardia. On page 107 look in the second section with the subheading “symptomatic bradycardia” You will see a numbered list with these three criteria in it.
      Kind regards,
      Jeff
