Bradycardia is a slow rhythm usually found to be under 60 bpm. There can be many forms of bradycardia.

Regardless of the underlying reason, if bradycardia is causing the patient to display  bradycardia-related symptoms, it should be treated.

Bradycardia ECG

An example of a bradycardia patient’s ECG might show the following:

  • Rhythm is regular
  • Rate is slow at less than 60 beats per minute
  • P waves are present, upright, and consistent
  • PR interval is between .12 and .20 seconds
  • The QRS complex is between .06 and .11 seconds
  • P wave to QRS ratio is 1:1

Cardiac Interpretation:

Because sinus bradycardia can result from so many things, it is important to get a thorough patient history, including a medication list and any other past medical problems.  If the patient is showing symptoms related to the bradycardia, the patient should be treated and underlying causes should be investigated.
