Abnormal ECG: Catecholamines

Clinical - Cardiovascular

Catecholamine surges are thought to be pathogenic in stress (takotsubo) cardiomyopathy (1). This catecholamine induced injury causes ventricular ballooning, dysfunction, and in some cases dysrhythmia and sudden death. The diagnosis is confirmed with echocardiography or cardiac magnetic resonance imaging. Coronary angiography may be necessary to rule out ischemic cardiomyopathy in some cases.
