Top 10 Questions for Cardiology Technician Interview

1. Explain the procedure of performing an electrocardiogram (ECG)?

In performing an electrocardiogram (ECG), I would follow these steps:

• First, I would gather the necessary equipment, which includes an ECG machine, electrodes, and conductive gel.
• I would then prepare the patient by explaining the procedure and ensuring that they are comfortable.
• Next, I would apply the electrodes to the patient’s chest, arms, and legs, ensuring that they are properly secured and making good contact with the skin.
• I would then start the ECG machine and begin recording the patient’s heart activity.
• Once the recording is complete, I would remove the electrodes and provide the patient with a copy of the ECG tracing.

2. What are the different types of cardiac catheters?

Diagnostic catheters

• Right heart catheter
• Left heart catheter
• Coronary catheter

Therapeutic catheters

• Balloon angioplasty catheter
• Stent catheter
• Atherectomy catheter

3. Describe the role of a cardiac technician during a cardiac catheterization procedure?

During a cardiac catheterization procedure, the cardiac technician plays a vital role in assisting the cardiologist. Responsibilities may include:

• Preparing the patient for the procedure and monitoring their vital signs throughout.
• Operating the fluoroscopy machine to visualize the heart and blood vessels.
• Inserting and manipulating catheters and other devices under the direction of the cardiologist.
• Administering medications and fluids as needed.
• Recording and interpreting data from the procedure.

4. What are the potential complications of a cardiac catheterization procedure?

Potential complications of a cardiac catheterization procedure include:

• Bleeding or bruising at the catheter insertion site
• Infection
• Damage to the heart or blood vessels
• Stroke
• Kidney damage
• Allergic reaction to contrast dye

5. Describe the different types of cardiac imaging tests and their indications?

Types of cardiac imaging tests and their indications:

• Echocardiography: Uses sound waves to create images of the heart, useful for evaluating heart structure and function
• Cardiac MRI: Uses magnetic fields and radio waves to create detailed images of the heart, useful for diagnosing heart defects and evaluating heart function
• Cardiac CT scan: Uses X-rays and computer technology to create cross-sectional images of the heart, useful for evaluating coronary arteries and heart valves
• Nuclear medicine scans: Use radioactive tracers to create images of blood flow to the heart, useful for diagnosing coronary artery disease and assessing heart function

6. What are the different types of pacemakers?

• Single-chamber pacemakers: Pace only one chamber of the heart, usually the right ventricle
• Dual-chamber pacemakers: Pace both the right atrium and right ventricle, coordinating the heart’s electrical activity
• Biventricular pacemakers: Pace both ventricles, improving heart function in patients with heart failure
• Leadless pacemakers: Small, wireless devices that are implanted directly into the heart, eliminating the need for pacemaker wires

7. Explain the process of defibrillation?

Defibrillation is a medical procedure that uses a high-energy electrical shock to restore a normal heart rhythm in patients experiencing ventricular fibrillation or ventricular tachycardia.

• Preparing the patient: The patient is sedated and electrodes are placed on their chest.
• Delivering the shock: A high-energy electrical shock is delivered to the heart through the electrodes.
• Assessing the patient: After the shock, the patient’s heart rhythm is monitored and further treatment may be necessary.

8. Describe the different types of implantable cardioverter-defibrillators (ICDs)?

• Single-chamber ICDs: Monitor and pace only the right ventricle, delivering shocks if needed
• Dual-chamber ICDs: Monitor and pace both the right atrium and right ventricle, providing more comprehensive protection
• Biventricular ICDs: Pace both ventricles and deliver shocks, used in patients with heart failure
• Subcutaneous ICDs: Implanted under the skin, eliminating the need for wires in the heart

9. What are the different types of cardiac resynchronization therapy (CRT) devices?

• CRT-P: Pacemaker with biventricular pacing, improves heart function in patients with heart failure
• CRT-D: Implantable cardioverter-defibrillator with biventricular pacing, provides protection against sudden cardiac arrest and improves heart function
• CRT-M: Cardiac resynchronization therapy with defibrillation and atrial pacing, used in patients with atrial fibrillation and heart failure

10. Describe the role of a cardiac technician in the management of patients with heart failure?

Cardiac technicians play a vital role in the management of patients with heart failure, including:

• Monitoring vital signs and assessing fluid status
• Performing electrocardiograms (ECGs) and other diagnostic tests
• Educating patients on heart failure management and medications
• Assisting with the insertion and management of cardiac devices
• Collaborating with the healthcare team to develop and implement treatment plans
