[Accelerated idioventricular rhythm before reperfusion. what does it mean? A Case Report].

Area of Science:

• Cardiology
• Electrophysiology

Background:

• Accelerated idioventricular rhythm (AIVR) is typically considered a benign cardiac arrhythmia.
• Its role during acute myocardial infarction (MI) as a marker of reperfusion is debated.
• AIVR is usually transient and hemodynamically stable.

Observation:

• A case of an adult male with inferior ST-segment elevation myocardial infarction (STEMI) is presented.
• The patient exhibited accelerated idioventricular rhythm.
• Crucially, AIVR occurred in the absence of any reperfusion therapy.

Findings:

• The presence of AIVR in this STEMI case, without reperfusion, challenges its traditional benign classification.
• This observation suggests AIVR may possess independent prognostic significance.
• Accurate electrocardiogram (ECG) recognition and recording of AIVR are vital.

Implications:

• The findings necessitate a re-evaluation of AIVR's prognostic value in acute myocardial infarction.
• Clinicians should consider AIVR as a potential indicator beyond simple reperfusion.
• Further research is warranted to elucidate the precise implications of AIVR in MI patients.
