Bradycardia

17 June 2025

Overview

Bradycardia is a condition where the heart beats more slowly than normal. For most adults, a typical resting heart rate ranges between 60 and 100 beats per minute (bpm). When the heart rate drops below 60 bpm, and especially if it causes symptoms, it may be diagnosed as bradycardia.

While a slow heart rate can be normal for some individuals, particularly athletes, bradycardia may also be a sign of an underlying heart problem that requires medical attention.

Common Symptoms of Bradycardia

Symptoms of bradycardia vary depending on how well the heart is able to pump blood throughout the body. Some people may be asymptomatic, while others may experience the following:

Dizziness or light-headedness
Fainting (syncope) or near-fainting spells
Fatigue or weakness
Shortness of breath
Chest pain or discomfort
Confusion or memory problems
Exercise intolerance

If bradycardia becomes severe or persistent, it can significantly impact your quality of life and overall health.

Causes of Bradycardia

Bradycardia may result from various conditions or external factors, including:

Age-related degeneration of the heart’s electrical system
Heart tissue damage from a previous heart attack or heart disease
Congenital heart defects (present from birth)
Hypothyroidism (underactive thyroid)
Sleep apnoea
Certain medications, including beta blockers and anti-arrhythmic drugs
Electrolyte imbalances
Inflammatory diseases such as myocarditis

When to Seek Medical Help

If you experience symptoms such as fainting, persistent fatigue, or shortness of breath—especially if you’re aware of a slow heart rate—it’s important to seek prompt medical evaluation. Left untreated, bradycardia can lead to complications such as heart failure, frequent fainting, or even cardiac arrest.

Diagnosis at Royal Buckinghamshire Hospital

At Royal Buckinghamshire Hospital, we offer a comprehensive diagnostic pathway for suspected bradycardia, including:

Electrocardiogram (ECG) to assess heart rhythm
Holter monitoring for continuous recording over 24–48 hours
Echocardiogram to evaluate heart function and structure
Blood tests to detect thyroid issues or electrolyte imbalances

Our experienced cardiology team ensures that every patient receives an accurate diagnosis and a personalised care plan.

Treatment Options

Treatment depends on the severity and underlying cause of your bradycardia. Options may include:

Adjusting or stopping medications contributing to a slow heart rate
Treating underlying conditions such as hypothyroidism
Pacemaker implantation for patients with persistent or symptomatic bradycardia
Lifestyle advice to support cardiovascular health

Our consultants will guide you through the best course of action, tailored to your specific condition.
