Sinus bradycardia


  • Atrial and ventricular rhythms are regular.
  • Atrial and ventricular rates are less than 60 beats per minute.
  • PR interval and QRS width are within normal limits.
  • Treatment may be necessary if the client is symptomatic (signs of decreased cardiac output).
  • A low heart rate may be normal for some individuals, such as athletes.



  • Attempt to determine the cause of sinus bradycardia; withhold medication suspected of causing the bradycardia and notify the PHCP.
  • Administer oxygen as prescribed for the symptomatic client.
  • Administer atropine sulfate as prescribed to increase the heart rate to 60 beats per minute.
  • Be prepared to apply a noninvasive (transcutaneous) pacemaker initially if the atropine sulfate does not increase the heart rate sufficiently.
  • Avoid additional doses of atropine sulfate, because this will induce tachycardia.
  • Monitor for hypotension and administer fluids intravenously as prescribed.
  • Depending on the cause of the bradycardia, the client may need a permanent pacemaker.
