Bradyarrhythmias

Bradyarrhythmias

Bradyarrhythmias (pronounced: bray-dee-uh-rith-mee-uhs) are a type of heart rhythm disorder where the heart beats slower than normal. This condition is also known as bradycardia.

Etymology

The term "Bradyarrhythmias" is derived from the Greek words "bradys" meaning slow, and "arrhythmia" meaning without rhythm.

Definition

Bradyarrhythmias are characterized by a heart rate of less than 60 beats per minute. This is slower than the normal heart rate of 60 to 100 beats per minute. Bradyarrhythmias can occur in healthy individuals, particularly during sleep or in athletes. However, they can also be a sign of several health issues, including heart disease and hypothyroidism.

Symptoms

Symptoms of bradyarrhythmias can vary depending on the severity of the condition. Some people may not experience any symptoms, while others may experience:

• Fatigue
• Dizziness
• Lightheadedness
• Fainting or near fainting
• Shortness of breath
• Chest pain

Causes

Bradyarrhythmias can be caused by:

• Heart disease
• Hypothyroidism
• Some genetic conditions
• Certain medications, including beta-blockers and calcium channel blockers
• Aging

Treatment

Treatment for bradyarrhythmias depends on the cause and severity of the condition. In some cases, no treatment is necessary. If the condition is caused by a medication, adjusting or changing the medication may resolve the issue. In more severe cases, a pacemaker may be needed to regulate the heart's rhythm.
