What Is Bradycardia?
Bradycardia is a slower-than-normal heart rate. In adults, it is generally defined as a resting heart rate of fewer than 60 beats per minute. While some healthy people, such as athletes, naturally have slower heart rates, bradycardia can also result from heart conditions, medications, or problems with the heart’s electrical system.
Whether bradycardia requires treatment depends on the underlying cause and whether it is producing symptoms.
Why Bradycardia Matters
If the heart beats too slowly, it may not pump enough oxygen-rich blood to meet the body’s needs. This can lead to fatigue, dizziness, fainting, or, in severe cases, serious heart complications.
Common Causes of Bradycardia
- Aging-related changes in the heart
- Heart disease
- Heart attack
- Problems with the heart’s electrical system
- Certain medications, including beta-blockers
- Hypothyroidism
- Sleep apnea
Common Symptoms
- Fatigue
- Dizziness
- Lightheadedness
- Fainting or near-fainting
- Shortness of breath
- Chest discomfort
- Difficulty exercising
- Confusion
How Is Bradycardia Diagnosed?
Healthcare providers may diagnose bradycardia using a physical examination, electrocardiogram (ECG), Holter monitor, event monitor, blood tests, and other cardiac evaluations to identify the underlying cause.
How Is Bradycardia Treated?
Treatment depends on the cause and severity of symptoms. It may include adjusting medications, treating underlying medical conditions, or implanting a pacemaker if the heart rate remains dangerously slow.
How Home Care Can Help
Home care professionals monitor pulse rate and symptoms, encourage medication adherence, observe for signs of worsening heart function, support healthy daily routines, and report concerning changes to the healthcare provider.
Home Care Tip
If you experience dizziness, fainting, or unusual fatigue along with a slow heart rate, seek medical evaluation promptly.
Frequently Asked Questions About Bradycardia
Is a slow heart rate always dangerous?
No. Many healthy athletes naturally have slow resting heart rates. Bradycardia becomes a concern when it causes symptoms or results from an underlying heart condition.
Can medications cause bradycardia?
Yes. Certain medications, including beta-blockers and some heart rhythm medications, can slow the heart rate.
Can home care professionals monitor someone with bradycardia?
Yes. Home care professionals can monitor pulse rate, observe for symptoms, encourage medication adherence, and communicate changes to the healthcare team.
When to Seek Immediate Medical Care
Seek emergency medical attention if bradycardia is accompanied by chest pain, severe shortness of breath, fainting, confusion, or loss of consciousness.
