    ObjectiveTo determine the frequency of intraventricular dyssynchrony among patients with left bundle branch block.MethodsThe study was conducted at Hayatabad Medical Complex, Peshawar, from January, 2017 to July, 2017. All patients aged 18 years and above with Left Bundle Branch Block (LBBB) on ECG with or without heart failure were included in the study. Patients with valvular heart disease, predominant diastolic heart failure, acute coronary syndromes or coronary revascularization in last three months and atrial fibrillation were excluded. Tissue Doppler Imaging (TDI) parameters were measured from 2-D images in apical 4-chamber and 2-chamber views. Consecutive non-probability sampling technique was used for sample collection.ResultsOur study included 159 patients. Mean age was 52 years with SD ± 2.74. Ninety-nine (62%) patients were male and 60 (38%) patients were female. One hundred and three (65%) patients had heart failure while 56 (35%) patients didn't have heart failure. More over in our study 124 (78%) patients had Intraventricular dyssynchrony while 35(22%) patients didn't have Intraventricular dyssynchrony.ConclusionThe incidence of Intraventricular dyssynchrony is high among patients with heart failure and left bundle branch block.
