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) |
| Notes |

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.
