Article Abstract
Triangular QRS-ST-T waveform electrocardiography pattern, so-called "shark fin sign," is a rare and highly mortal electrocardiography finding, which usually occurs in adult patients with coronary occlusion. Here, we reported the first paediatric case occurring in a striking "triangular waveform electrocardiography pattern" due to myocarditis during COVID-19 infection.

Shark fin or triangular QRS-ST-T waveform ECG pattern, also known as lambda-wave ST elevation or giant R wave syndrome, is a particular ECG presentation where QRS complex, ST-segment and T-wave are fused in a unique complex. Originally described in some patients with ST-segment elevation myocardial infarction (STEMI) during the acute phase, it has been found to be associated with a high risk of ventricular fibrillation and cardiogenic shock as well as with a high in-hospital mortality. However, shark fin ECG pattern has also been reported in patients with non-acute coronary syndrome related ST-elevation (NASTEP), including stress-induced takotsubo syndrome (TTS).

Background: The triangular QRS-ST-T waveform is a rare presentation of ST-segment elevation acute myocardial infarction associated with a poor in-hospital prognosis.
Objective: To evaluate the incidence and clinical implications of the QRS-ST-T waveform pattern.
Methods: Clinical data from non-pregnant adult patients who presented as STEMI activations at a single institution between 2017 and 2021 were reviewed.

Primary ventricular fibrillation (PVF) may occur in the early phase of ST-elevation myocardial infarction (STEMI) prior to primary percutaneous coronary intervention (PCI). Multiple electrocardiographic STEMI patterns are associated with PVF and short-term mortality including the tombstone, Lambda, and triangular QRS-ST-T waveform (TW). We aimed to compare the predictive value of different electrocardiographic STEMI patterns for PVF and 30-day mortality.
