Atrial Flutter

This page provides a definition of atrial flutter followed by an synopsis of EKG features. Links to our practice drills, quizzes, lessons and interactive guides can be found below.

Definition of Atrial Flutter

Atrial flutter is a very rapid pattern of atria contraction. Unlike atrial fibrillation, atrial flutter's electrical activity in the atria is coordinated. This rapid rate (250 to 350 times per minute) is too fast to allow the conduction of each impulse to the ventricles.

Atrial Flutter Rhythm Strip

The following table summarizes the key features of an atrial flutter EKG rhythm strip.

Rhythm Regular or irregular
Rate Fast (250-350 bpm) for Atrial, but ventricular rate is often slower
P Wave Not observable, but saw-toothed flutter waves are present
PR Interval Not measurable
QRS Normal (0.06-0.10 sec)

EKG Training

A good starting point for learning EKG interpretation is our EKG Basics training course. The course provides training on the key features of an EKG tracing. These features include observing P-wave forms, measurement of EKG intervals and segments, assessment of rhythm, calculating heart rate, and the evaluation of other relevant wave segments. The arrhythmia practice drills allow students to build skills interactively.

EKG Practice Drills

The heart arrhythmia practice drills provide a test EKG tracing and users are asked to identify the type of arrhythmia. Many of these drills include tachycardia EKG tracings. Each answer is immediately evaluated and the correct classification of the EKG tracing is provided, along with a detailed explanation. A directory of arrhythmias is also provided.

ECG Quiz

The quiz is structured like a classroom exam. The quiz present twenty EKGs. Users answer each question and at the end of the quiz, a fully graded report is provided. This graded report provides scoring as well as the correct answer to each question. Top scores and mean scores are also provided. This quiz draws its questions from a library of over 300 EKGs, allowing users to take the quiz multiple times.

ECG Monitor Challenge (beta version)

Try the beta version of our ECG monitor challenge. This quiz uses a simulated patient monitor with moving waveform instead of a paper tracing. As with the quiz described above, twenty questions are presented, then a graded report is available.
