Adult Bradycardia Algorithm
Bradycardia Algorithm Review
Major Rhythms found in the Bradycardia Algorithm
1st Degree Heart Block
2nd Degree Heart Block
Type 1 also known as Mobitz 1 also known as Wenkenbach
Type 2 also known as Mobitz 2
3rd Degree heart Block also known as Complete Heart Block
See ECG for Everyone Video & Flashcard ECG Rhythms for more detail on how to read Bradycardia ECGs.
Sinus Bradycardia asymptomatic vs. Sinus Bradycardia symptomatic
Asymptomatic bradycardia may be the normal rhythm for athletes who are very fit. Their resting heart rates may be in the 40-60 beats per minute range but they will have normal blood pressures and normal energy levels. On the other hand, patients who have slow heart rates due to cardiac issues will have a heart rate less than 60 beats per minutes and frequently less than 50 beats per minute, symptoms such as hypotension, and the symptoms are caused by the bradycardia.
Functional or Relative Bradycardia
Functional or Relative Bradycardia occurs when the heart rate is within normal ranges 60-100 beats per minutes but the heart rate is insufficient for the patient’s condition such as a patient in septic shock.

If it is not as evidenced by vital signs such as BP, level of consciousness, cap refill time, etc. then the healthcare provider should follow the Bradycardia Algorithm. Administer atropine, prepare to initiate transcutaneous pacing, and give second line drugs such as epinephrine or dopamine. It is important to determine underlying causes and treat and reverse them if possible. The H’s and T’s can help with determining and treating underlying causes.
The Bradycardia algorithm uses three medications: Atropine, Epinephrine, and Dopamine. Atropine 0.5 mg given IV/IO push every 3-5 minutes up to a maximum dose of 3 mg is the first drug to be given to all symptomatic bradycardic patients.
If atropine is ineffective, then while the team is preparing to initiate transcutaneous pacing epinephrine or dopamine infusions may be given. The dose for a Dopamine infusion is 2-20 mcg/kg/min. The dose for an Epinephrine infusion is 2-10 mcg/min.
