Ventricular tachycardia is a type of abnormal heart rhythm, or arrhythmia, that originates in the ventricles of the heart. It is characterized by a fast, regular heart rate that starts in the lower chambers of the heart, or ventricles. Ventricular tachycardia can be potentially life-threatening if it is sustained or occurs in individuals with underlying heart conditions. Treatment options for ventricular tachycardia include medications, implantable devices like pacemakers or defibrillators, and ablation procedures to correct the abnormal heart rhythm. Research in this area focuses on better understanding the causes and mechanisms of ventricular tachycardia, as well as developing more effective treatments to manage and prevent this condition.
