Bradycardia
Algorithm
Updated 10/01/2021
If symptomatic or deteriorating bradycardia with HR < 60 BPM
►Establish IV Access, consider IO if attempts at IV are not successful
(For stable patients, obtain 12 lead. With signs of poor perfusion or other symptoms start therapy)
▼
►Atropine: 1 mg IV / / IO / IM approximately every 3 minutes as needed to correct bradycardia to a max of 3 mg
For systolic BP less than 90 (paced or not capture) or no response to Atropine; and Lungs clear:
▼
►250 mL NS bolus IV, may repeat 3 times to 1 liter (assess lung sounds, discontinue fluid infusion if rales develop)
▼
If unable to attain IV/IO or Atropine fails to improve heart rate, continue Atropine dosing and start pacing
▼
►Initiate Pacing (See Transcutaneous Pacing)
Transcutaneous Pacing
Set Rate at 70 BPM and mAto 0
Slowly increase mA until electrical (Monitor) and mechanical (Pulse) capture (max 120 mA) If still symptomatic increase the heart rate from 70 BPM (max of 100 BPM)
▼
►Versed (Midazolam): up to 5 mg IV titrate to attain sedation
If IV cannot be established and BP greater than 90 systolic
▼
►Versed (Midazolam): 5 mg IN (may repeat once after 3 minutes)
▼
OK to try Pacing again after admin of drugs and fluids
OK to administer Atropine while starting Pacing, if Atropine alone is not working
Obtain 12-Lead EKG if immediate pacing not required
