Technical Skills & Knowledge

• 5. What is the purpose of an EKG and how does it work?

An EKG, or electrocardiogram, is a non-invasive procedure that records the electrical activity of the heart. It helps doctors diagnose heart conditions such as arrhythmias and heart attacks.

• 6. Can you explain the different intervals and waves on an EKG reading?

The P-wave represents the electrical impulse that causes the atria to contract. The QRS complex represents the electrical impulse that causes the ventricles to contract, and the T-wave represents the electrical recovery of the ventricles.

• 7. How do you identify and troubleshoot any technical issues with EKG equipment?

I am familiar with a variety of EKG machines and know how to troubleshoot common issues such as loose or faulty electrodes, poor signal quality, or incorrect settings. If I cannot resolve the issue, I will notify my supervisor and follow the proper protocol for maintenance and repairs.

• 8. Do you have experience with Holter and event monitoring? If so, can you explain the difference between the two?

Yes, I have experience with both Holter and event monitoring. Holter monitoring records heart activity for 24 hours, while event monitoring is used for longer periods, typically 14 to 30 days. Event monitors also have event recorders, which allow patients to record their symptoms for further analysis.
