Bradycardia is a heart condition characterized by an unusually slow heart rate. Specifically, it's defined as a resting heart rate of fewer than 60 beats per minute (BPM) in adults. Normally, a healthy adult's heart rate ranges between 60 to 100 BPM at rest. When the heart beats slower than this range, it's considered bradycardia.
This condition occurs due to various factors affecting the heart's electrical system. It can result from natural aging, certain medications, heart tissue damage from heart attacks, infections, or other underlying health issues affecting the heart's ability to generate electrical impulses.
Bradycardia isn't always problematic, especially for athletes or individuals with a high level of physical fitness. Their hearts often beat more efficiently and may naturally have lower resting rates, but for others, bradycardia might lead to symptoms like dizziness, fainting, fatigue, shortness of breath, or chest pain.
Understanding the symptoms and causes is crucial for diagnosis. Doctors typically use electrocardiograms (ECGs or EKGs) to measure the heart's electrical activity and determine the heart rate. Holter monitors or event monitors might be used for continuous monitoring to capture irregular heart rhythms.
Treatment for bradycardia depends on its severity and symptoms. Some cases may not require treatment, while others might involve lifestyle changes, adjusting medications, or implanting a pacemaker, a small device that helps regulate the heart's rhythm.
It's important to consult a healthcare professional if experiencing symptoms or if there's a concern about heart rate irregularities. Bradycardia's impact can vary from person to person, and understanding the individual's overall health is crucial in managing this condition effectively.
