The ECG findings of an old anterior wall MI include the loss of anterior forces, leaving Q waves in leads V1 and V2. This is a cause ofpoor R wave progression, or PRWP. Here is an example of an old anterior wall MI: Enlarge Note: To distinctly say that an...
Three markers of regional response in both normal and ischemic areas were used: surface ECG electrode, a force gauge in series with left ventricular outer wall fibers, and coronary blood inflow to each region as...doi:10.1016/0002-9149(74)90909-6Frederic Pashkow...
Left anterior fascicular block (LAFB) is a heart disease identifiable from an abnormal electrocardiogram (ECG). It has been reported that LAFB is associated with an increased risk of heart failure. Non-specific intraventricular conduction delay due to the lesions of the conduction bundles and slow...
In acute myocardial infarction, stress hyperglycemia impairs coronary microcirculation, potentially causing the “no-reflow” phenomenon after PCI, which hinders effective reperfusion and increases myocardial damage [46]. Prolonged hyperglycemia exacerbates myocardial ischemia, leading to cardiomyocyte apoptosis an...
The ECG showed Q waves in leads II, III, and aVF, and the QS pattern in leads V1 and V2. The echocardiogram showed a reduced left ventricular ejection fraction of 44%, and akinesis of the apex and inferior wall, with hypokinesis of the antero-septal wall, suggesting old myocardial ...
[1]Coronary anomalies of the LAD have been noted to be associated with myocardial ischemia/infarction, increased risk of atherosclerosis, aortic valve disease, increased risk of bacterial endocarditis, increased incidence of cardiomyopathy, volume overload, heart failure, and increased risk of ...

cardiac cycle because systolic and diastolic aortic blood pressures exceed the pressures within these chambers. The RCA and its branches supply most of the RV, but the RV anterior wall also may receive blood from branches of the LAD. RV dysfunction may occur because of RCA or LAD ischemia. ...
Therefore, a conservative approach is typically recommended because spontaneous angiographic healing occurs in most cases except in patients presenting with ongoing ischemia, recurrent chest pain, hemodynamic instability, or LMT dissection. In our patient with LMT dissection, we had to select whether to ...
