EKG Practice Test

An electrocardiogram (EKG or ECG) is a test used to detect heart problems and monitor heart health. An EKG practice test will help you prepare for the rhythms you will encounter during the real test and gain experience with identifying specific EKG strips.

If you are preparing to become a certified EKG technician, you will need to craft an efficient study plan that includes taking practice tests.

Summary: Use our EKG practice below to prepare for your upcoming exam.

Take an EKG practice test listed below to help you get started. We highly recommend you take one before creating a study plan so that you know where to focus your studies.

One of the most difficult parts of the EKG exam is identifying EKG strips. This is an area that requires practice in order to master. Here are some free resources to help you get started.

An EKG (electrocardiogram test) is a noninvasive procedure that measures electronic signals in the heart to ensure that it’s functioning normally. It’s simple and painless, detailing the rate and strength of each heartbeat.

Physicians use this important test to diagnose major problems with the heart such as arrhythmias or coronary artery disease, or to monitor how certain treatments such as medications or pacemakers are working.

An EKG identifies the following heart disorders:

  • Arrhythmia (irregular heartbeat)
  • Blocked arteries
  • Risk of heart disease
  • Risk of heart failure
  • Previous heart attacks
  • Other forms of damage to the heart
  • Therapeutic measurement

Medical personnel who administer this test must be certified by taking an EKG certification test. This is a complex exam that requires a great deal of preparation including in-depth studies and regular practice tests to help you measure the progress of studies.

Please Note: Sometimes the terms EKG and ECG are used interchangeably. They are different abbreviations that refer to the same test. An electrocardiogram is a test used to measure how the electricity in a person’s heart is functioning.

The certified EKG technician (CET) exam is given by the National Healthcareer Association (NHA). The exam consists of:

  • 100 scored items
  • 2 hour time limit

One of the best ways to prepare for this exam is by taking practice exams and becoming familair with the types of questions and what the strips will look like.

Here are some study tips that will help you get started:

  • Start by creating a detailed study plan. Each session should include practice strips to help you memorize these essential patterns.
  • Study the major responsibilities of EKG certified techs. This includes setting up and administering an EKG, prepping patients, and the interpretation and delivery of test results.
  • Get hands-on training. Students are encouraged to volunteer to get as much hands-on experience as possible. Medical facilities sometimes seek students as interns. In exchange for your assistance, they will provide experience in the field.
  • Take notes. Writing down information while watching videos or reading through study materials helps memorize it.
  • Use prep materials to learn the material. Practice exams and study guides are great resources for learning all of the information.

What is the difference between ECG and EKG?

This can be confusing at first. However, ECG and EKG both refer to the same test. EKG uses the German spelling for abbreviation while ECG uses the English spelling for abbreviation.

How do you memorize EKG strips?

Hours upon hours of studying are required to interpret EKG strips but the most important ones are lethal strips because they must be identified quickly. These include ventricular fibrillation, ventricular tachycardia, and asystole. Most students choose to study those strips initially.

With that said, there is a quick and easy four-step method that you can use to identify EKG strips. It goes like this:

  • Determine the Rate: Is it slow, medium, or fast?
  • Determine the Rhythm: Is it regular or irregular? A regular pattern is consistent in the distance between each QRS. 
  • P-Wave: Is a P-Wave present before every QRS? Is there a QRS after every P-Wave?
  • Use the process of elimination to deduce the type of strip being viewed.
