Practice
EKG rhythm strip practice
One strip at a time. Answer, see the strip measured, read why, and go again until the rhythms you miss stop being the ones you miss. Five strips a day are free, with no account; a plan makes it as many as you want.

What the practice does
- 492,000different practice strips
- 12,000 of each of 41 rhythms. The rate, the intervals and the wave shapes change every time, so there is no picture to memorize.
- 552,000strips measured before release
- A separate program that sees only the finished trace reads every strip back. It has to find the rhythm, the rate and the intervals we report.
- Every stripexplained from its own numbers
- After your answer the strip is marked up with calipers, and the explanation quotes this PR interval, this rate, this dropped beat.
- 3 kindsof question
- Name the rhythm, measure the PR interval, find the heart rate. The wrong answers are the rhythms that really get confused with it.
- Five free strips every day
- Three to name and two to measure, new each day and the same for everyone, so a class can do them together. No account is needed.
- Strips that do not repeat
- 492,000 different strips: 12,000 of each of 41 rhythms, with the rate, the intervals and the wave shapes different every time. At a hundred strips a day you would not see one twice in thirteen years.
- An explanation of every strip
- After each answer the strip is marked up with its own measurements, and the explanation quotes the numbers on that strip, not a textbook example.
- Name it or measure it
- Name the rhythm, or read the PR interval or the heart rate off the paper. Wrong answers are the rhythms people really confuse it with.
- Your weak rhythms
- Every rhythm you have met is listed with how often you got it right. One click practises the ones you miss, mixed with their look-alikes.
- Missed strips come back
- A strip you get wrong is kept so that you can try the same strip again. It leaves the list when you get it right.
Simulated strips, for education and practice only. Every practice strip comes from a set that our tests have read back and measured; how that is done is on the about and methods page. To measure intervals with calipers, open the caliper trainer. To read about a rhythm before practising it, start from the rhythm library. To practise on paper, print the 20-strip practice test with answers.
Where this comes from
The criteria and rules on this page are taken from published sources, and every strip is drawn to them and then measured by a separate program before it is shown. How the strips are made and checked
- American Heart Association. CPR and Emergency Cardiovascular Care guidelines: adult cardiac arrest, bradycardia and tachycardia algorithms. Which rhythms are shockable, and the first actions for the arrest rhythms, slow rhythms and fast rhythms.
- American Heart Association, American College of Cardiology and Heart Rhythm Society. Recommendations for the standardization and interpretation of the electrocardiogram, part I (Circulation, 2007). The paper every strip is drawn on: 25 mm per second and 10 mm per millivolt.
- University of Arkansas. How to Interpret Rhythm Strips, in the open EKG Interpretation manual. The five-step read and the normal ranges for rate, PR interval and QRS.
