Cardio Pt 1 RVMI verified questions and solution A+ grade
What causes Right Ventricular Myocardial Infarction (RVMI)? - - RVMI occurs due to
occlusion of the Right Coronary Artery (RCA), which supplies blood to the right ventricle.
How does RCA blockage affect the left ventricle? - - RCA blockage can cause inferior Left
Ventricular Myocardial Infarction (LVMI) and potentially RVMI.
What is the role of the right ventricle (RV)? - - The RV pumps blood through the lungs for
oxygenation and provides preload to the left ventricle.
What is the consequence of impaired RV stroke volume? - - Impaired RV stroke volume
leads to decreased pulmonary flow, hypoxia, and decreased left heart filling.
What is the classic clinical triad for RVMI? - - Hypotension, clear lung fields, and jugular
venous distension (JVD).
Why is clear lung fields significant in RVMI? - - Clear lung fields indicate that the problem
is forward flow into the lungs, not backup from the left ventricle.
What diagnostic test is key for suspected RVMI? - - Right-sided ECG (lead V4R) is the key
test, with ST elevation in V4R being highly specific for RVMI.
What are the effects of decreased left ventricular preload? - - Decreased LV preload can
lead to decreased cardiac output, tissue ischemia, and potential shock.
What is the first-line treatment for RVMI? - - Volume loading with IV fluid boluses to
restore RV preload.
