Management of STEMI with Complete Heart Block Using Transcutaneous Pacing: Case Report

Background: Transcutaneous cardiac pacing is a rapid, non-invasive method for stimulating the heart through skin electrodes and is vital in managing life-threatening Bradyarrhythmia. This case report highlights its role in a patient with severe arrhythmia following myocardial infarction. Case Presentation: A 53-year-old male presented to the emergency department with chest pain. His condition progressed from STEMI to a third-degree atrioventricular (AV) block, which led to cardiac arrest. Transcutaneous pacing stabilized the patient, allowing time for coronary intervention. Following revascularization, the AV block resolved completely, and the patient recovered without residual conduction disturbances. Conclusion: Prompt recognition and management of third-degree AV block in patients with ST-elevation myocardial infarction is essential. Emergency transcutaneous pacing, followed by timely coronary intervention, can be life-saving and restore normal cardiac conduction.
