Arrhythmias are abnormal heart rhythms that can lead to symptoms like palpitations, dizziness, or even life-threatening conditions like sudden cardiac arrest. Management of arrhythmias may involve medications, electrical cardioversion, catheter ablation, or implantation of a pacemaker or defibrillator. These treatments aim to restore normal rhythm and prevent complications. Each of these interventions plays a crucial role in improving patient outcomes and managing complex cardiovascular conditions.
