‘De Winter’ electrocardiographic pattern in left bundle branch block and acute coronary occlusion: a case report

Recognition of electrocardiographic patterns associated with acute coronary occlusion is crucial for diagnosis and prompt reperfusion, reducing morbidity and mortality. The 'De Winter' pattern is an equivalent to STEMI. Patients with pre-existing conditions that affect QRS amplitude and width, such as the left bundle branch block, pose an additional challenge.
