Impulses, or electrical signals, travel through both the left and right chambers of your heart to make it pump. The heart has two upper (atria) and two lower chambers (ventricles). This study emphasizes the prognostic significance of echocardiographic assessment of left ventricular volume after CRT implantation in LBBB patients with mild HF. Electrical impulses within the heart muscle cause it to beat (contract).

The main complication of bundle branch block, right or left, is to progress to a complete block of the electric conduction from the upper chambers of the heart to the lower, also called complete heart block or third-degree heart block. [1] In this condition, activation of the left ventricle of the heart is delayed, which causes the left ventricle to contract later than the right ventricle . It began in the age of enlightment (renaissance). Heart disease symptoms in women may differ from men. But a bundle branch block delays the electrical signal, therefore, the ventricle that receives the delayed signal will contract at a later time.
