diaphragmatic flutter

flutter /flut·ter/ (flut´er) a rapid vibration or pulsation.

---

atrial flutter  cardiac arrhythmia in which the atrial contractions are rapid (250 to 350 per minute), but regular.

diaphragmatic flutter  peculiar wavelike fibrillations of the diaphragm of unknown cause.

impure flutter  atrial flutter in which the electrocardiogram shows alternating periods of atrial flutter and fibrillation or periods not clearly one or the other.

mediastinal flutter  abnormal motility of the mediastinum during respiration.

pure flutter  atrial f.

ventricular flutter  (VFI) a possible transition stage between ventricular tachycardia and ventricular fibrillation, the electrocardiogram showing rapid, uniform, regular oscillations, 250 or more per minute.

diaphragmatic flutter

n.

Rapid rhythmical contractions of the diaphragm, averaging around 150 per minute, that resemble atrial flutter clinically and sometimes electrocardiographically.

---

diaphragmatic flutter,

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

---

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.
