Low Heart Rate (Bradycardia)

A low heart rate, or bradycardia, occurs when the heart beats less than 60 times per minute while awake. In some cases, a low heart rate is perfectly normal, especially among elite athletes with resting heart rates as low as 40 beats per minute. However, for non-athletes, a consistently low heart rate might indicate a problem in the heart’s natural conducting system.

Types of Bradycardia

Bradycardia comes in various forms, and understanding them can help identify potential causes and treatments:

Sinus Bradycardia

This type occurs when the heart rate falls below 60 beats per minute. In healthy individuals, this may not cause complications. It becomes a concern. When is consistently below 40 beats per minute or causes symptoms.

Sick Sinus Syndrome

When the heart’s natural pacemaker, the sinus node, starts slacking off, people might experience sinus pauses and other arrhythmias. Some individuals with this syndrome may need an artificial pacemaker.

Tachycardia-Bradycardia Syndrome

Common in people with atrial fibrillation, this syndrome causes the heart to alternate between fast and slow beats.

Heart Block

An abnormality in the heart’s electrical conduction system results in slower heart rates. The severity varies, and treatment depends on the type of heart block.

Ectopic Bradycardia

It occurs when a different part of the heart becomes the pacemaker. It can happen in the atria, junctions, or ventricles.

Causes of Bradycardia

Various factors can lead to bradycardia, ranging from mild to severe. These include:

  • Sleep apnea (often treatable)
  • Structural heart problems
  • Sinus node dysfunction
  • Heart disease
  • Heart attack
  • Hypothyroidism (underactive thyroid)
  • Medications (beta-blockers, calcium channel blockers, etc.)
  • Other medical conditions (e.g., amyloidosis, Lyme disease)

Symptoms of Bradycardia

If someone experiences any of the following symptoms alongside a low heart rate, it is essential to seek medical advice:

  • Dizziness
  • Fainting
  • Fatigue
  • Confusion
  • Trouble breathing

Additionally, a very low can harm other organs, especially in cases of low blood pressure or shock.

Tips to Raise
