“…It is also known as λ wave or giant R waves . This pattern has also been reported in acute myocarditis, as well as Takotsubo cardiomyopathy, representing repolarization abnormalities in those settings. Although this pattern is associated with acute myocardial infarction and frequently complicated by cardiogenic shock or cardiac arrest, this patient presented transiently in the setting of severe COVID-19, and the cause of death was respiratory failure.…”

“…It is also known as 'Lambda-wave', 'giant R waves', or 'triangular QRS-ST-T waveform' [4]. This ECG pattern consists of blurring of the QRS complex due to its fusion with the STsegment and the T-wave showing a triangular lambda pattern where a positive deflection in the leads suggests ischemia in corresponding areas [1]. According to one study done by Cipriani et al [3], only 1.4% of patients admitted due to STEMI developed this ECG pattern, illustrating its rarity.…”

“…Shark Fin pattern is an uncommon but high-risk electrocardiographic (ECG) pattern formed by fusion of QRS, ST-segment, and T waves [1]. Myocardial infarction with shark fin ECG pattern most commonly involves occlusion of the left main coronary artery and is associated with a high risk of death due to cardiac arrest and cardiogenic shock [2].…”

Shark fin electrocardiographic (ECG) pattern, also known as 'Lambda-wave', 'giant R waves', or 'triangular QRS-ST-T waveform' is a dangerous ECG pattern associated with ST-elevation myocardial infarction (STEMI). It is formed by the fusion of QRS, ST, and T waves and predicts the high risk of mortality due to cardiogenic shock and ventricular fibrillation. The management should be aggressive with reperfusion via thrombolysis or percutaneous intervention, ideally in the intensive care unit with ventricular assist devices. This ECG pattern may be misdiagnosed as wide complex tachycardia or the ECG changes of hyperkalemia. Thus, differentiating it from other conditions causing similar ECG changes and prompt management is highly important to save the patient from serious complications. Here we have presented a case of STEMI with shark fin ECG associated with pulmonary edema (Killip class III acute myocardial infarction).

“…The transient diffuse tombstone‐like ECG changes ( Shark fin sign ) seen in our patient were most consistent with multivessel coronary vasospasm likely secondary to hemopericardium (finding never described earlier). "Shark Fin sign," or Triangular QRS‐ST‐T waveform however have been previously reported in association with other cardiac conditions, such as Takotsubo cardiomyopathy, acute coronary syndrome, and acute myopericarditis 1‐4 …”
