Heart rhythm disorders, also known as arrhythmias, occur when the heart beats too fast, too slow, or irregularly. This can disrupt the normal flow of blood throughout the body, leading to symptoms like palpitations, dizziness, or even fainting. Some common types of arrhythmias include atrial fibrillation, ventricular tachycardia, and bradycardia.
These disorders can be caused by various factors, including heart disease, high blood pressure, or stress. While some arrhythmias may be harmless, others can be serious and require medical attention. Treatment options range from lifestyle changes and medications to procedures like cardioversion or ablation to restore a normal heart rhythm.
