Bradycardia


Bradycardia is where the heart rate is below 60 beats per minute when at rest. It can be a normal finding in athletes or during sleep (sometimes 40-50 bpm particularly when in deeper sleep stages), but in other cases it can indicate an underlying health condition.

Symptoms

  • Fatigue
  • Dizziness or lightheadedness
  • Fainting or near-fainting spells
  • Shortness of breath
  • Chest pain or discomfort
  • Confusion or memory problems

Since the heart rate is lower than normal the brain revives less oxygen hence why patients often experience symptoms like dizziness and fatigue.

Treatments

Untreated bradycardia can lead to complications such as heart failure, cardiac arrest, or even death if serious enough. Treatment may include:

  • Pacemaker
  • Atropine (a medication that increases heart rate)
  • Adjusting medications that may be causing bradycardia
