✍️ Sample IBHRE Questions & Answers
1. Ranolazine's antiarrhythmic properties are primarily due to inhibition of which sodium current?
Ranolazine inhibits the late (persistent) sodium current, reducing intracellular sodium and calcium overload that can trigger arrhythmias.
2. In cardiac electrophysiology, what is an "ablation" procedure primarily used for?
Cardiac ablation is a therapeutic procedure used to treat various arrhythmias by targeting and neutralizing the specific heart tissue responsible for generating or sustaining abnormal electrical signals. Using heat (radiofrequency ablation) or cold (cryoablation), the procedure creates small scars that block the faulty electrical pathways. This effectively restores a normal heart rhythm and prevents future episodes of arrhythmia.
3. The standard tilt table test is typically performed at what upright angle?
The Westminster protocol and most international guidelines recommend a tilt angle of 70 degrees as the standard for evaluating neurally mediated syncope.
4. In the VASIS (Vasovagal Syncope International Study) classification, Type 2B vasovagal syncope is characterized by:
VASIS Type 2B is defined as a cardioinhibitory response with asystole of ≥3 seconds, which may favor pacemaker implantation in selected patients.
5. Standard 0.5 mm lead equivalent aprons typically attenuate scattered radiation by approximately?
Standard lead aprons attenuate approximately 90–95% of scattered radiation at diagnostic X-ray energies, substantially reducing operator dose.
6. Which of the following is a key consideration when performing an electrophysiology study (EPS) on a pediatric patient?
Performing an electrophysiology study (EPS) on pediatric patients often requires the use of general anesthesia. Children, especially younger ones, may not be able to remain still or cooperate for the extended duration of the procedure, which involves inserting catheters and inducing arrhythmias. General anesthesia ensures patient comfort, safety, and the ability to obtain accurate diagnostic information.
