Bradycardia - Medical Glossary

Understanding Bradycardia?

Bradycardia is a condition where the heart beats slower than normal, which can reduce oxygen supply to the body. While some individuals, like athletes, naturally have a lower heart rate, others may develop bradycardia due to heart disease, medication side effects, or metabolic imbalances.

Symptoms and Signs of Bradycardia?

Symptoms of bradycardia include fatigue, dizziness, shortness of breath, fainting (syncope), chest pain, confusion, and weakness. In severe cases, it can lead to heart failure or cause insufficient blood flow to the brain, resulting in serious complications.

Causes and Risk Factors for Bradycardia?

Bradycardia can result from aging, heart disease, high blood pressure, hypothyroidism, electrolyte imbalances, sleep apnea, or medication side effects (such as beta-blockers and calcium channel blockers). Conditions affecting the heart's electrical system, like sick sinus syndrome or heart block, can also contribute.

Treatment Options for Bradycardia?

Mild cases may not require treatment, but if symptoms occur, doctors may adjust medications, recommend lifestyle changes, or treat underlying conditions. Severe cases may require a pacemaker to regulate the heart rate and ensure adequate blood flow.

When to Seek Medical Help for Bradycardia?

Seek immediate medical attention if you experience severe dizziness, chest pain, fainting, extreme fatigue, or difficulty breathing, as these may indicate a serious heart issue. A healthcare provider can perform an ECG and other tests to determine the cause and recommend treatment.
