Abstract

Objective

To determine the frequency and types of bradyarrhythmias in patients presenting with acute inferior wall myocardial infarction.

Methods

This Descriptive case series was conducted at accident & emergency and medicine departments, King Edward Medical University, Mayo Hospital Lahore for 6 months from 1st July to 31st December 2017. After ethical approval, total 350 clinically diagnosed IWMI patients of age 30-65 years of either genders presenting in emergency department, with ST segment elevation of >1mm in ECG leads II, III, aVF were included in the study through non-probability, purposive sampling. Patients were assessed on ECG to determine the bradyarrhythmias like sinus bradyarrhythmia, 1st, 2nd & 3rd degree AV blocks developed in patients during 1st 7 days after IWMI.The collected data was analysed statistically by using SPSS version 20.

Results

In the study, the mean age of the patients was noted as 50.12±7.84 years. There were 253 (72%) male and 97 (28%) female patients. Out of 350 patients of IWMI, Bradyarrhythmia were present in 209 (60%) while absent in 141 (40%) patients. Sinus bradycardia was found in 80 (38.3%) patients, 1st degree AV Block was observed in 49 (23.4%) patients, 2nd degree AV Block was observed in 45 (21.5%) patients and 3rd degree AV Block was observed in 35 (16.7%) patients.

Conclusion

It was concluded that frequency of bradyarrythmias is very high among patients of IWMI with the presence of all the major types. Thus, in future we will recommend practitioners & cardiologists to be more careful about better management & clinical outcome.
