  Background & Objective : Heart failure is a clinical syndrome and increases in rate by aging. Because changes in ECG and electrolytes are variable, specific and sometimes independent to the disease with different methods to be diagnosed, in this study we tried to find a way to diagnose them.   Materials & Methods: This is a retrospective descriptive-analytic study. Data was collected from dec...

Patient-specific modelling of cardiac electrophysiology in heart-failure patients

AIMS Left-ventricular (LV) conduction disturbances are common in heart-failure patients and a left bundle-branch block (LBBB) electrocardiogram (ECG) type is often seen. The precise cause of this pattern is uncertain and is probably variable between patients, ranging from proximal interruption of the left bundle branch to diffuse distal conduction disease in the working myocardium. Using realis...

The successful treatment of end stage of heart failure associated with complete right bundle branch block with biventricular pacemaker placement.

Biventricular pacing has been used to treat patients with symptomatic heart failure, systolic left ventricular dysfunction and intraventricular conduction delays. This modality is usually reserved for the treatment of patients with a left bundle branch block pattern on electrocardiogram. We report the successful use of biventricular pacing in a patient with heart failure and a right bundle bran...

Right Bundle-Branch Block and Response to Cardiac Resynchronization Therapy

Cardiac resynchronization therapy (CRT) in appropriately selected patients has been shown to improve cardiac function, heart failure symptoms, and survival.1,2 On the basis of results of large, randomized trials, current American Heart Association/American College of Cardiology/Heart Rhythm Society guidelines recommend consideration of CRT in patients with cardiomyopathy on optimal medical ther...
