What minimum duration is standard for a conventional Holter monitor recording to capture intermittent arrhythmias?
Answer: 24 hours
The standard Holter monitoring duration is 24 hours, which captures a full cycle of daily activities including sleep to detect intermittent arrhythmias.
Which EKG lead placement configuration is most commonly used in a standard Holter monitor setup?
Answer: Modified 5-lead or 7-lead chest configuration
Holter monitors typically use a modified 5-lead or 7-lead configuration attached to the chest to approximate standard EKG views while allowing patient mobility.
During a Bruce Protocol stress test, what happens at each successive stage?
Answer: Both treadmill speed and incline increase
The Bruce Protocol increases both speed and grade at each 3-minute stage to progressively intensify the cardiac workload.
A patient's stress test EKG shows 2 mm horizontal ST depression in leads V4-V6 at peak exercise. What does this finding most likely indicate?
Answer: Significant myocardial ischemia in the lateral wall
Horizontal ST depression of 2 mm or more during exercise strongly suggests significant myocardial ischemia in the territory supplied by the affected coronary artery.
What is the primary advantage of an event monitor over a standard 24-hour Holter monitor?
Answer: It can record over weeks to capture infrequent symptoms
Event monitors can be worn for weeks or months, making them ideal for capturing arrhythmias that occur too infrequently to be caught in a 24-hour Holter recording.
What is the significance of a drop in systolic blood pressure greater than 10 mmHg during an exercise stress test despite increasing workload?
Answer: It suggests severe coronary artery disease or left ventricular dysfunction
An exercise-induced drop in systolic blood pressure indicates the heart cannot increase cardiac output appropriately, suggesting severe CAD or pump failure.
