Heart rhythm disorders

Heart rhythm disorders, or arrhythmias, occur when the heart's electrical signals that control heartbeat become irregular, too fast, too slow, or erratic. This can result in palpitations, dizziness, fatigue, or fainting. Some arrhythmias are harmless, while others can increase the risk of stroke or heart failure. Common types include atrial fibrillation, where the upper chambers beat chaotically, and ventricular arrhythmias, affecting the lower chambers. Causes may include heart disease, electrolyte imbalances, or stress. Treatment options range from lifestyle changes and medications to electrical devices like pacemakers or procedures such as ablation, aiming to restore a normal, efficient heartbeat.
