Abstract

Background: Patients with high degree AVB had higher incidence of in hospital complications including cardiogenic shock, syncope, post MI angina, re-infarction and mortality. But data is scarce. So we conducted this study to get evidence regarding complications of RV infarction with inferior wall myocardial infarction (IWMI).

Aims and Objective: To find the association of in hospital high degree atrioventricular block with and without right ventricular involvement in patients presenting with acute inferior wall myocardial infarction.

Material and methods: This cohort study was done at Cardiology department of Punjab Institute of Cardiology, Lahore over a period of Six months from 15-06-2017 to 14-12-2017. Patients were divided in two groups i.e. group I with RV infarction and group II without RV infarction. Then patients were admitted in cardiology wards and were followed-up for 3 days. On third day, Second and third degree AVB develops in the presence of narrow QRS complex, then high degree AVB was labelled.

Results: Frequency of AVB in patients with RV infarction was significantly higher than patients without RV infraction. i.e. 16.8% vs. 3.2%. Relative risk showed that risk of AVB was 5.25 times more among patients with RV infarction. Patients who had RV infraction and AVB block (n=21) among them 71.43% had 3rd degree and 28.57% patients had 2nd degree AVB block.

Conclusion: Frequency as well as risk of high degree atrioventricular block was significantly higher in patients with RV infarction.

Keywords: In hospital, high degree, Atrioventricular block, Right ventricular, Acute Inferior wall, Myocardial infarction.
