When the heart beats too slowly

Backed by 1 well supported study

Estimated percentage of adults over 65 affected (CDC, 2023).

2× higher

Older adults are twice as likely to experience bradycardia compared to younger people (NIH, 2023).

60 beats per minute

A heart rate below 60 beats per minute is typically considered bradycardia (AHA, 2023).

Overview

In plain language

Bradycardia is a condition where the heart beats slower than normal, typically fewer than 60 beats per minute. It can affect older adults, leading to fatigue, dizziness, and other complications. While a slow heart rate can be normal for some, in others it may signal a problem that requires medical attention.

Bradycardia is a condition characterized by a slower than normal heart rate, typically defined as fewer than 60 beats per minute. While a slow heart rate can be normal and healthy for some individuals, particularly athletes or those who engage in regular physical activity, it can signal an underlying health issue in others. Common causes of bradycardia include aging-related changes in the heart, heart diseases such as coronary artery disease or heart attack, and certain medications. Symptoms may include fatigue, dizziness, fainting spells, or shortness of breath. If left untreated, bradycardia can lead to serious complications, such as heart failure or sudden cardiac arrest. Treatment depends on the cause and severity of the condition and may involve adjusting medications, treating underlying health issues, or using a pacemaker to regulate the heart rate. If you experience symptoms or have concerns about your heart health, it's important to consult with a healthcare provider. They can offer guidance and support to ensure your heart is functioning optimally, providing peace of mind and better health outcomes.

Key Information

Review the most relevant symptoms, risk factors, and common care approaches in one place.

Risk Factors

Several factors can increase the risk of developing this condition, including:

Age: The risk of bradycardia increases with age as heart function naturally declines.
Heart conditions: History of heart attacks or heart disease can lead to bradycardia.
Medications: Certain drugs for high blood pressure or heart disease can slow the heart rate.

Symptoms

Symptoms can vary but often include:

Fatigue: Feeling unusually tired or weak.
Dizziness: Experiencing light-headedness or fainting spells.
Shortness of breath: Difficulty breathing during routine activities.

Coping Strategies

Coping with this condition can be challenging, but these strategies may help:

Regular Check-ups: Monitoring heart health with your doctor can prevent complications.
Medication Management: Reviewing medications with healthcare providers to avoid side effects.
Lifestyle Changes: Regular exercise and a healthy diet can support heart health.

Common Treatments

Treatment focuses on managing symptoms and improving quality of life:

Pacemaker: A device implanted to regulate heart rate.
Medication Adjustments: Changing prescriptions to avoid slowing the heart.
Addressing Underlying Conditions: Treating conditions like thyroid disorders that may cause bradycardia.

Treatment Option

Magnesium

Magnesium supports muscle function, nerve health, and relaxation. It helps regulate heart rhythm, energy production, and sleep quality — common concerns for older adults.
