Slow Heart Rate (Bradycardia): Understanding Causes, Symptoms, and Treatments • Yesil Health AI

What Is Bradycardia?

Bradycardia, commonly referred to as a slow heart rate, is a condition where the heart beats fewer than 60 times per minute. While a normal resting heart rate for adults typically ranges from 60 to 100 beats per minute, bradycardia can be a sign of underlying health issues or, in some cases, a normal physiological response, especially in athletes or those who are physically fit.

Understanding Heart Rate

The heart rate is a vital sign that reflects how well the heart is functioning. It can be influenced by various factors, including:

Age: Heart rates tend to slow down with age.
Fitness Level: Athletes often have lower resting heart rates due to their enhanced cardiovascular efficiency.
Medications: Certain medications, especially those for heart conditions, can lower heart rate.
Medical Conditions: Conditions like hypothyroidism or heart block can lead to bradycardia.

In some cases, bradycardia may not cause any symptoms and can be harmless. However, when the heart rate drops too low, it can lead to serious complications, making it essential to understand this condition fully.

Types of Bradycardia

Bradycardia can be classified into several types, including:

Sinus Bradycardia: This is the most common form, where the heart’s natural pacemaker (the sinus node) sends out signals at a slower rate.
Heart Block: This occurs when the electrical signals in the heart are partially or completely blocked, leading to a slower heart rate.
Junctional Bradycardia: This type arises from the junction between the atria and ventricles, causing a slower heart rate.

Understanding the type of bradycardia is crucial for determining the appropriate treatment and management strategies.

Bradycardia Symptoms

Recognizing the symptoms of bradycardia is vital for timely intervention. While some individuals may experience no symptoms at all, others may face a range of issues that can significantly impact their quality of life. Common symptoms include:

Common Symptoms of Bradycardia

Fatigue: A persistent feeling of tiredness or lack of energy.
