Frequency and Types of Bradyarrhythmias in Patients Presenting with Acute Inferior Wall Myocardial Infarction (AIWMI)
Abstract
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.Keywords:
