Key result
Among patients with STEMI, the most common arrhythmias were sinus tachycardia (31%) and bundle branch block (30%), with 76% of arrhythmias occurring during the first hour of hospitalization.
Observational (n=100)
Arrhythmias are highly prevalent in the first 72 hours of STEMI, with the majority occurring in the first hour, and ventricular tachycardia and complete heart block are associated with higher mortality.
Ventricular arrhythmias and CHB in STEMI associate with higher mortality; leaves open whether intensified early monitoring improves outcomes in larger trials.
BACKGROUND elevation myocardial infarction is an acute emergency, more than 50% of deaths due to STEMI occur within first 1 hour, due to various arrhythmias. Various arrhythmia can complicate the course of STEMI. This study was done to access the and pattern of arrhythmias complicating STEMI and the prognostic implications of these arrhythmias. AND METHODS 100 patients were included in the study that fulfilled the required criteria. They underwent detailed history taking and systemic . Patients were monitored through cardiac monitor and serial ECG recording were taken specially if any rhythm were observed and data was entered in a pretested proforma. 100 patients, 60 were male and 40 were female. Commonest arrhythmias noticed in this study were sinus tachycardia (31%), followed by bundle branch block (30%), ventricular arrhythmia (25%) AV blocks (20%) sinus bradycardia (18%), arrhythmia (4%) and AIVR in 1%. Mortality was more in patients with ventricular tachycardia and complete block. Majority of arrhythmias (76%) occur during first hour of hospitalization. commonest arrhythmia encountered were sinus tachycardia followed by bundle branch block (BBB), AV block and sinus , AV block and sinus bradycardia were common with IWMI and ventricular arrhythmia and bundle branch block were with AWMI.

Sinha et al. (2018) conducted an observational in ST segment elevation myocardial infarction (STEMI) (n=100). ST segment elevation myocardial infarction was evaluated on Incidence and pattern of arrhythmias. Among patients with STEMI, the most common arrhythmias were sinus tachycardia (31%) and bundle branch block (30%), with 76% of arrhythmias occurring during the first hour of hospitalization.
