Unusual Tachycardia in a Patient With Chest Pain and Bradycardia

“…This ECG pattern occurs typically during the hyperacute phase of acute myocardial infarction, variant angina, exercise treadmill testing, or during balloon occlusion in PCI. Recently, this ECG pattern has also been reported in acute myocarditis, as well as takotsubo cardiomyopathy . However, to our knowledge, this is the first described case of atropine-induced giant R wave–like ST-segment elevation.…”

“…It is also known as a shark-fin pattern or λ wave. 3,4 This pattern is closely associated with ventricular fibrillation and short-term mortality. 5 It may be misdiagnosed as ventricular tachycardia when heart rate is increased.…”

“…Recently, this ECG pattern has also been reported in acute myocarditis, as well as takotsubo cardiomyopathy. [3][4][5][6][7] However, to our knowledge, this is the first described case of atropine-induced giant R wave-like ST-segment elevation.…”

“…It is characterized by the transient development of very tall and wide R waves merged with ST-segment elevation (T wave). It is also known as a shark-fin pattern or λ wave . This pattern is closely associated with ventricular fibrillation and short-term mortality .…”
