Question 1

The Mason Likar modification is what?

Accepted Answer

A different arrangement for placing electrodes in a 12-lead EKG

Answer

The Mason-Likar modification is a specific technique used in electrocardiography, particularly during exercise stress tests. It involves repositioning the limb electrodes from the standard distal limb placement to the torso, which helps reduce motion artifact and improve signal quality during physical activity.

Question 2

An ST depression accompanied by strong U waves and flattened T waves results from what electrolyte abnormality?

Accepted Answer

Hypokalemia

Answer

Hypokalemia, or low potassium levels, is a common cause of specific EKG changes. These changes typically include ST segment depression, prominent U waves (a small wave following the T wave), and flattening or inversion of the T waves, reflecting altered myocardial repolarization due to the electrolyte imbalance.

Question 3

Which of the following is used to evaluate the calcium in coronary arteries?

Accepted Answer

Electron beam computed tomography

Answer

Electron Beam Computed Tomography (EBCT), also known as ultrafast CT, is a specialized imaging technique used to detect and quantify calcium deposits in the coronary arteries. The presence and amount of coronary artery calcium (CAC) are strong indicators of atherosclerotic plaque burden and cardiovascular risk.

Question 4

What is the method where a balloon is used to flatten plaque up against an arterial wall to provide more room inside the artery for better blood flow?

Accepted Answer

Percutaneous Transluminal Coronary Angioplasty (PTCA)

Answer

Percutaneous Transluminal Coronary Angioplasty (PTCA), often simply called angioplasty, is a minimally invasive procedure used to widen narrowed or obstructed blood vessels. A balloon-tipped catheter is inserted and inflated at the site of the plaque, compressing it against the arterial wall to restore adequate blood flow.

Question 5

What does the Holter EKG monitoring test function entail?

Accepted Answer

Tracks abnormalities on EKG as they occur throughout the day

Answer

A Holter monitor is a portable device that continuously records the heart's electrical activity (EKG) for 24 to 48 hours, or sometimes longer. This extended monitoring helps detect intermittent arrhythmias or other EKG abnormalities that might not be captured during a brief, standard EKG in a clinic setting.
