FREE ECG Practical Content and Preparation Questions and Answers
What is a common study method for preparing for the ECG certification exam?
Preparation focuses on understanding the heart’s anatomy, recognizing normal and abnormal rhythms, and mastering ECG procedures. Surgical and pharmacological knowledge are not directly relevant to ECG certification exams.
Which of the following rhythms would be considered normal in an ECG reading?
A sinus rhythm indicates a normal heart rhythm initiated by the SA node. Other rhythms, such as ventricular fibrillation or atrial flutter, indicate abnormalities.
What is the purpose of the P wave in an ECG tracing?
The P wave corresponds to the electrical activity that causes the atria to contract (depolarization). Ventricular depolarization is represented by the QRS complex, while repolarization is shown in other parts of the ECG.
What is the primary function of an EKG technician during an ECG procedure?
The technician's role focuses on preparing the patient, placing the leads correctly, and obtaining a high-quality ECG recording.
Which part of the heart’s anatomy is responsible for initiating the electrical impulse measured in an ECG?
The SA node is the natural pacemaker of the heart, initiating the electrical impulses that spread through the heart and are recorded in an ECG. The AV node and other components help relay the signal but do not initiate it.
