FoEM CBR22- Cardiology Exam What underlying pathologic process distinguishes myocardial infarction from angina/unstable angina? Atherosclerotic plaque rupture → exposed endothelium → clot attaches → reduced blood flow; if cell death occurs (usually due to complete vascular obstruction) then positive trop and MI; if no cell death occurs then negative trop and angina/unstable angina. What is the difference between transmural and nontransmural infarction? Transmural: usually STEMI, la...

ECG provides correct answers a record of the electrical activity occurring in the heart throughout the cardiac cycle how an ECG is administered correct answers exercise technician can administer a resting 12-lead ECG test, but a highly-skilled and qualified physician should interpret the results (Heyward, 2010). The resting ECG provides baseline data (for future resting and exercise 12-lead ECG tests), and can also be used to detect contraindications to exercise testing Einthoven correct a...

12 Lead ECG placement? The precordial leads, also known as chest leads or V leads, view the heart in the horizontal plane. They include six unipolar leads (V1, V2, V3, V4, V5, and V6) that measure electrical activity between the center of the heart and a positive electrode on the chest wall. Heart conduction 1. Sinoatrial node 2. Atrioventricular node 3. Atrioventricular bundle 4. Right and left bundle branches 5. Purkinje fibers What does the P wave represent? -Atrial depolarization...

NPCC RN 4S T1 Telemetry Questions with complete solution 2023/2024ECG or EKG - correct answer A record of the electrical activity of the heart, consisting of waves called P,Q,R,S,T and sometimes U 12 Lead - correct answer 10 electrodes (6 on the chest, 4 on the limbs) Limb electrodes away from bony prominances If you must place limb leads on trunk note on the strip because the readings will be skewed.The chest electrodes provide the V (Vector) or precordial lead views: V1 through V6. • ...
