Elderly ventricular tachycardia

Elderly ventricular tachycardia (VT) refers to rapid arrhythmias originating below the bifurcation of the bundle of His, including the bundle branches, Purkinje fibers, and ventricular myocardium, with a rate exceeding 100 beats/min and consisting of 3 or more consecutive spontaneous ventricular electrical depolarization activities, including monomorphic nonsustained and sustained ventricular tachycardia as well as polymorphic ventricular tachycardia. Clinical symptoms may include palpitations, chest tightness, chest pain, blurred vision, and syncope. Its clinical characteristics are sudden onset and sudden termination after treatment or spontaneously. During an episode, patients suddenly experience palpitations, increased heart rate, mental agitation, fear, precordial discomfort, and a feeling of fullness and throbbing in the head or neck.
