Heart rhythm disorders, specifically atrial fibrillation and arrhythmia: Underlying factors, indicators, and remedies explained.
Heartbeat anomalies, often referred to as arrhythmias, can be a problem with the speed or rhythm of your heart. These irregularities might result in a rapid, slow, or erratic heartbeat. While occasional skipped beats are common, frequent irregular rhythms can cause symptoms like palpitations, dizziness, and more, according to the National Heart, Lung, and Blood Institute (NHLBI).
One common arrhythmia is atrial fibrillation (A-fib or AF), where the top chambers of the heart contract irregularly. Dr. Lawrence Phillips, a cardiologist and assistant professor at NYU Langone Medical Center in New York City, explains that A-fibrillation is caused by abnormal electrical impulses originating from the top chamber of the heart.
A-fibrillation can lead to heart disease or worsen existing conditions in some cases. It may resolve on its own for others, while for many, it becomes a long-term problem.
But while A-fibrillation is often thought of as an issue with the heart's electrical system, mounting evidence suggests that various factors and medical conditions may cause or exacerbate the issue. These may include structural changes within the left atrium, genetic factors, disrupted metabolism, and more. Scientists have discovered over 160 genes associated with A-fibrillation, according to a 2021 review published in the European Journal of Human Genetics.
Common symptoms of A-fibrillation include an irregular heart rhythm, heart palpitations, and lightheadedness. The intensity and duration of symptoms may vary, from brief episodes to continuous symptoms.
If left untreated, A-fibrillation can lead to complications like stroke, heart failure, or even death. It is crucial to seek medical attention if experiences any irregular heart rhythm symptoms. Treatment options for A-fibrillation include blood thinners to reduce stroke risk, medications to control the heart rate and restore normal rhythm, or in severe cases, surgical procedures like electrical or catheter ablation, maze surgery, or even heart transplantation in rare cases.
The American Heart Association, Mayo Clinic, and National Institutes of Health provide additional resources for further information on A-fibrillation and heart health management.
- The irregular heart rhythms caused by atrial fibrillation (A-fib or AF) can indirectly impact overall health and wellness, as they may lead to chronic diseases such as heart failure and even stroke, according to the National Heart, Lung, and Blood Institute (NHLBI).
- The causes of atrial fibrillation are not only confined to the heart's electrical system; factors like structural changes within the left atrium, genetic factors, disrupted metabolism, and mental health conditions may also contribute, as suggested by scientific research and a 2021 review in the European Journal of Human Genetics.
- Additionally, managing mental health and maintaining cardiovascular health is vital in the prevention and management of atrial fibrillation and other medical conditions, as emphasized by health and wellness organizations such as the American Heart Association, Mayo Clinic, and National Institutes of Health.
