What Is Bradycardia?
Bradycardia, commonly referred to as a slow heart rate, is a medical condition characterized by a heart rate that is less than 60 beats per minute. While a normal resting heart rate for adults typically ranges from 60 to 100 beats per minute, bradycardia can occur in healthy individuals, particularly athletes, as a result of their well-conditioned hearts. However, in some cases, it may indicate an underlying health issue that requires attention.
Understanding Heart Rate
The heart rate is a vital sign that reflects how well your 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 high level of cardiovascular fitness.
- Medications: Certain medications, especially those for heart conditions, can lower heart rate.
- Medical Conditions: Conditions such as hypothyroidism or heart block can lead to bradycardia.
Bradycardia can be classified into two main types: sinus bradycardia and non-sinus bradycardia. Sinus bradycardia occurs when the heart’s natural pacemaker, the sinoatrial (SA) node, sends signals at a slower rate. Non-sinus bradycardia can result from issues with the electrical pathways of the heart.
Causes of Bradycardia
There are several potential causes of a low heart rate, including:
- Heart Conditions: Damage to the heart from a heart attack or other conditions can disrupt the electrical signals.
- Electrolyte Imbalances: Low levels of potassium or calcium can affect heart function.
- Inflammation: Conditions like myocarditis can lead to bradycardia.
- Medications: Some drugs, particularly beta-blockers and sedatives, can slow the heart rate.
If you suspect you have bradycardia, it’s essential to consult a healthcare professional for a proper diagnosis and treatment plan. Resources like Yesil Health AI can provide evidence-based health answers to help you understand your condition better.
