diaphragmatic flutter


Also found in: Dictionary, Thesaurus, Legal, Encyclopedia, Wikipedia.

flutter

 [flut´er]
a rapid vibration or pulsation.
atrial flutter a cardiac arrhythmia in which the atrial contractions are rapid (230–380 per minute), but regular. Two types, I and II, are distinguished according to rate; Type I is also more amenable to cardioversion. In Type I the atrial rate is usually 290 to 310 per minute but can range from 230 to 350. In Type II the atrial rate is usually 360 to 380 per minute but can range from 340 to 430.
diaphragmatic flutter peculiar wavelike fibrillations of the diaphragm of unknown cause.
impure flutter atrial flutter in which the atrial rhythm is irregular.
mediastinal flutter see mediastinal flutter.
pure flutter atrial flutter in which the atrial rhythm is regular.
ventricular flutter a possible transition stage between ventricular tachycardia and ventricular fibrillation, the electrocardiogram showing rapid, uniform, and virtually regular oscillations, 250 or more per minute.

di·a·phrag·mat·ic flut·ter

rapid rhythmical contractions (average, 150 per minute) of the diaphragm, simulating atrial flutter clinically and sometimes electrocardiographically.

diaphragmatic flutter

rapid, rhythmic contractions of the diaphragm. The condition may simulate atrial flutter.

di·a·phrag·mat·ic flut·ter

(dī'ă-frag-mat'ik flŭt'ĕr)
Rapid rhythmic contractions (average, 150 per minute) of the diaphragm, simulating atrial flutter clinically and sometimes electrocardiographically.

flutter

a rapid vibration or pulsation.

atrial flutter
cardiac arrhythmia in which the atrial contractions are rapid (200-320 per minute), but regular.
diaphragmatic flutter
peculiar wavelike fibrillations of the diaphragm of unknown cause. See also synchronous diaphragmatic flutter.
impure flutter
atrial flutter in which the atrial rhythm is irregular.
mediastinal flutter
abnormal mobility of the mediastinum during respiration.
pure flutter
atrial flutter in which the atrial rhythm is regular.
flutter valve
in an intravenous infusion apparatus, a floating bead in the fluid chamber that allows air to enter the system but prevents fluid from escaping. Its movement is often viewed as an indicator of the speed of fluid infusion, but it is inaccurate.
ventricular flutter
a possible transition stage between ventricular tachycardia and ventricular fibrillation, the electrocardiogram showing rapid, uniform, and virtually regular oscillations, 250 or more per minute.
