The Guiding Significance Of Electrocardiographic QRS In Patients With Heart Failure Suffered From Cardiac Resynchronization Therapy

Cardiac resynchronization therapy is an effective mechanical treatment for patients with heart failure and a wide QRS in recent years.It can improve the clinical symptoms,reduce rehospitalization rate and mortality significantly.What's more,The decrease in the amplitude of the QRS complex can be used as an indicator of heart failure improvement.The decrease in the amplitude of the QRS complex can be used as an indicator of heart failure improvement.Prolonged QRS duration,true complete left bundle branch block is a reliable indicator of the effectiveness of the treatment of CRT.The fragmentation QRS complex is a predicator of CRT,which helps to screen the best patients for CRT.
