Key result
Continuous echocardiography detects transient myocardial stunning before characteristic type-A Wellens ECG patterns appear.
Echocardiography can detect transient myocardial ischemia (stunning) prior to the development of characteristic Wellens ECG changes.
Echocardiography may enable earlier ischemia detection in select patients; leaves open its impact on outcomes pending prospective studies.
Continuous echocardiography captured transient myocardial stunning before the appearance of a type-A Wellens ECG pattern. This case highlights the value of echocardiography for detecting transient myocardial ischemia before characteristic electrocardiographic changes become apparent.
