ECG manifestations of left main coronary artery (LMCA) occlusion and critical stenosis

…LCx supplies the posterior descending artery (PDA) in a left dominant circulation (i.e. 10 15% of cases). Clinically, patients present with severe chest pain…

ECG localization of myocardial infarction / ischemia and coronary artery occlusion (culprit)

…PDA (posterior descending coronary artery), which supplies the inferior wall of the left ventricle, determines the coronary artery dominance ( Figure 1 ). A right dominant system…

Posterior acute myocardial infarction (STEMI)

…difficult to differentiate right ventricular hypertrophy (RVH) from posterior acute ischemia. Both these conditions cause ST segment depressions in V1–V3 along with large R…

ST elevation myocardial infarction (STEMI) without ST elevations on 12-lead ECG

…posterolateral and right ventricular infarction may occur simultaneously (if both territories are affected by the same artery occlusion). Approximately 30% of patients with posterolateral infarction…

Cardiac thromboembolism: cardiac sources of embolism

…TIA (transient ischemic attack), coronary artery occlusion, and peripheral embolization. Stroke is the third leading cause of death in Western countries, and ultrasound studies are…

Pulmonary Embolism (PE)

…thrombus is pumped from the right ventricle through the pulmonary valve into the main pulmonary artery. Depending on the size and form of the thrombus…

ST-Elevation Myocardial Infarction Complicated by Cardiogenic Shock

…zone. Coronary Occlusion and Myocardial Injury STEMI generally results from abrupt reduction in coronary blood flow caused by thrombotic occlusion of a previously atherosclerotic artery…

The left ventricle in myocardial ischemia and infarction

…from the right coronary artery (RCA). The RCA also supplies the inferior left ventricular wall in over 90% of all individuals. Hence, a proximal occlusion …

ST-Segment Elevation Myocardial Infarction: Diagnosis and ECG Criteria

…with an initial STEMI pattern has myocardial infarction as the final diagnosis. The underlying process usually involves acute thrombotic obstruction of an epicardial coronary artery…

ST segment depression in myocardial ischemia and differential diagnoses

…segment depressions with prominent T waves in the majority of the chest leads may indicate an acute occlusion in the LAD (left anterior descending artery)…
