He is mildly short of breath and also starts sweating profusely. He takes two Tums which fail to relieve his symptoms and his wife calls 911. The ambulance comes within 10 minutes of the 911 call and they perform an in-field ECG. The automatic ECG interpretation reads "Acute anterior wall...
What changes that occur in an ECG demonstrate ischemia late in the ischemic cascade? What is the cardiac test that helps in evaluating ventricular function? Why is an ECG sometimes called an EKG? Which pressure is lowest during ventricular systole? a.) right ventricula...
Which wave on the ECG trace marks the onset of ventricular systole and why? Can an EKG show ventricular contraction? Why or why not? What would happen if there were a blockage to the anterior interventricular artery? What is an ECG or an EKG? What are some of the possible causes (...
What is an inferior heart attack? Inferior wall myocardial infarction (MI)occurs from a coronary artery occlusion with resultant decreased perfusion to that region of the myocardium. Unless there is timely treatment, this results in myocardial ischemia followed by infarction. ...
Which is worse ST depression or elevation? Conclusion: In patients with a first acute anterior MI treated with primary PCI,ST elevation in inferior leadshad significantly worse short-term and long-term outcomes compared to no ST change or ST segment depression. ...
How might exercise provoke myocardial ischemia? A proximal LAD lesion is a blockage in the left anterior descending artery, also known as the anterior interventricular artery. Explain why a heart attack caused by an obstruction of this artery is sometimes referred to as the "widowmaker" heart. De...
What are the consequences of incorrect placement of EKG leads? What happens when thoracic volume increases? What do you think would happen to the blood flow to the body if there were a blockage to the anterior interventricular artery? Which of the following conditions i...
Explain how ischemia can cause a myocardial infraction and Why is immune suppression necessary after a transplant? What is a heart stroke? explain its treatment and prevention. What would happen if there were a blockage to the ante...
Left anterior oblique, (c) cranial of right coronary anatomy (stenosis 50% on the proximal right coronary). EKG performed afterwards showed normal sinus rhythm with LBBB, without ST-segment abnormalities that could indicate ischemia (Figure 3). Figure 3. EKG after emergent coronarography; sinus...
