Background: Recently, the deleterious effects of left bundle branch block (LBBB) on left ventricular systolic function have been taken into consideration.
Ventricular Tachycardia in the Absence of Structural Heart Disease
Ventricular tachycardia structurally normal heart
2015/8/5
In up to 10% of patients who present with ventricular tachycardia (VT), obvious structural heart disease is not identified. In such patients, causes of ventricular arrhythmia include right ventricular...
