Arrhythmias and electrophysiology focus on understanding the electrical activities of the heart and their role in maintaining a regular heartbeat. Advanced mapping techniques and ablation therapies have revolutionized the treatment of conditions like atrial fibrillation and ventricular tachycardia. Electrophysiology studies provide critical insights into identifying arrhythmic triggers and pathways, enabling precise interventions. Innovations such as leadless pacemakers and implantable cardioverter defibrillators (ICDs) have enhanced the management of life-threatening arrhythmias. Researchers are also delving into the genetic basis of arrhythmias, aiming to develop personalized therapeutic strategies. This domain continues to evolve, offering hope for improved quality of life and reduced mortality rates for patients with rhythm disorders.
