Abstract

Learning Objectives: Learn how to identify and differentiate the shark fin EKG pattern from other EKG patterns and abnormalities. Explore the potential diagnostic and prognostic implications of the shark fin EKG pattern, including its association with increased risk of arrhythmias and sudden cardiac death. Background: The Lambda-wave ECG, also known as the Shark fin or Thombostone pattern, has been linked to ST-elevation myocardial infarction's (STEMI) hazardous implications. It is characterized by merged QRS, ST, and T waves, forming a 'triangular QRS-ST-T waveform' or 'giant R waves.' This treacherous signature poses an alarming risk, with chances of cardiogenic shock and ventricular fibrillation leading to fatality. To tackle this peril, implementing swift thrombolysis or percutaneous intervention for reperfusion is critical for successful treatment. For optimal outcomes, the preferred setting to utilize ventricular assist devices is the ICU. Misdiagnosis can happen and be seen as either wide complex tachycardia or ECG changes induced by hyperkalemia. Imperative to prevent severe complications, early detection and treatment are crucial. We are reporting three cases of this Ekg pattern.
