Abstract
Objective: To find out the frequency of ischemic heart disease in patients with
conduction disorders requiring permanent pacemaker implantation.
Methodology: This cross sectional descriptive study was carried over 78 patients
at Electrophysiology Department, Cardiology, Hayatabad Medical Complex,
Peshawar from September 2014 till September 2015 for a period of one
year who presented with conduction defects and had been hospitalized for
permanent pacemaker implantation. Coronary angiography (CAG) was carried
out in all patients to diagnose ischemic heart disease (IHD). We determined
the frequency of various degrees of ischemic heart disease in different types of
heart blocks.
Results: Out of 78 patients, there were 42 (53.8%) males and 36(46.2%) females.
53 patients (67.9%) had coronary artery disease. Patients with age more than 40
years were having the highest frequecy of IHD 26(33.3%). Regarding the severity
of IHD, 21.8% had mono-vessel disease ,60.3% had two- vessel disease and
17.9% had three-vessel disease. 25 patients (32.1%) had no significant lesion on
coronary angiography.
Conclusion: Ischemic heart disease was present in high frequency in patients
with chronic conduction disorders and the most common artery involved was
right coronary artery.
