Atrial flutter  

Atrial flutter.   

Atrial flutter with 5:1 conduction  

The rhythm is irregular.  No P waves are seen but there are some flutter waves present.  The flutter waves that are seen best in leads II, III, and aVF.  

This page show a patient with atrial flutter with a long period of arrest.

Identify the following rhythms. 1. 2. 3. 4. 5. Answers 1. 2nd degree heart block type I The rhythm is irregular with a rate of 60/min.   The P waves are uniform and upright.   There is some splitting of the P wave which is often seen with biatrial enlargement.   There is progressive elongation of the PR interval over successive beats.   There is a dropped P wave after the 2nd QRS complex.   The QRS complexes are narrow.   PR:  .20/.24/..26/.30 sec.   QRS:  .08 sec,  QT:  .44 sec.   Interpretation:  2nd degree heart block type I 2. Accelerated junctional changing to sinus rhythm The rhythm is slightly irregular.   The heart rate is 83/min.   The P waves are negative or possibly biphasic in complexes 1 through 5 and then are positive in the remaining complexes.   The QRS complexes are narrow.  PR:  .10 sec,  QRS: ...

Identify the following rhythms. 1. 2. 3. 4. 5. Answers 1. 2nd degree heart block type II The rhythm is irregular.   The rate is 30/min.  There are upright, uniform P waves present but not all of them are associated with a QRS complex.  A non-conducted P wave follows each QRS complex.  The PR interval is constant on the conducted P waves.  There are two PVCs present, the 1st complex and the 4th complex.   PR:  .36 sec,  QRS:  .12 sec,  QT:  .48 sec.   Interpretation: 2nd degree heart block type II 2. Atrial flutter The rhythm is irregular with a rate of 90.   Flutter waves are present.  No ectopic beats are seen.  PR:---,  QRS:  .12 sec,  QT:.44 sec.   Interpretation:  Atrial flutter. 3. Atrial paced The rhythm is regular with a rate of 75/min.   A small...

Identify the following rhythms. 1. 2. 3. 4. 5. Answers 1. Atrial flutter with variable ventricular response The rhythm is irregular with a rate of 60/minute.   Multiple P waves or flutter waves are present in a 3:1 and 4:1 ratio.   No ectopic beats are seen.  PR:---,  QRS: .08 sec,  QT: .24 sec. Interpretation: Atrial flutter with variable ventricular response 2. Complete heart block The rhythm is regular with a rate of 38/min.   There are some small upright P waves seen but they are associated with the QRS complexes.   The atrial rate is 60/min.   No ectopic beats are seen.  PR:  ---,  QRS:  .16 sec,  QT:  .44 sec.   Interpretation:  Complete heart block 3. Normal sinus rhythm The rhythm is regular with a heart rate of 100/min.   The P waves are uniform, upri...
