Question 1

Cardiac tamponade during an EP procedure is recognized by which constellation of findings?

Accepted Answer

Hypotension, elevated venous pressure, and equalized diastolic pressures

Answer

Hypertension and bradycardia

Answer

Isolated sinus tachycardia

Answer

ST-segment elevation in anterior leads

Question 2

Why is systemic heparin anticoagulation routinely administered during left-sided EP procedures?

Accepted Answer

To prevent thromboembolism from catheter and sheath surfaces in the left heart

Answer

To prevent hematoma at the femoral access site

Answer

To reduce post-procedure pulmonary embolism risk only

Answer

To decrease ablation lesion size

Question 3

Air embolism during EP procedures is prevented primarily by?

Accepted Answer

Careful flushing and de-airing of all sheaths and catheters before insertion

Answer

Using dry needles for vascular access

Answer

Using the smallest available catheter size

Answer

Rapid catheter insertion to minimize air entry time

Question 4

The 'safe zone' for femoral vascular access lies?

Accepted Answer

Below the inguinal ligament where the common femoral vessels are accessible

Answer

Above the inguinal ligament over the external iliac vessels

Answer

Within the femoral triangle near the knee

Answer

Medial to the femoral nerve only

Question 5

Vascular closure devices (VCDs) after EP procedures are primarily used to?

Accepted Answer

Achieve hemostasis with reduced manual compression time

Answer

Prevent access site infection

Answer

Monitor post-procedure blood pressure

Answer

Prevent deep venous thrombosis

Question 6

Post-procedure pseudoaneurysm formation at the femoral access site is most commonly associated with?

Accepted Answer

Arterial access with inadequate hemostasis or high puncture

Answer

Venous access with small sheaths

Answer

Use of vascular closure devices

Answer

Anticoagulant reversal immediately after the procedure
