Flutter is a rapid vibration or pulsation. The difference between flutter and fibrillation is that flutter is well organized while fibrillation is not. For example, atrial flutter consists of well-organized but over-rapid contractions of the atrium of the heart (usually at a rate of 250-350 contractions per minute). Atrial flutter is a serious and [..]

Well-organized but overly rapid contractions of the atrium of the heart (usually at a rate of 250-350 contractions per minute). Flutter refers to a rapid vibration or pulsation. The difference between flutter and fibrillation is that flutter is well organized while fibrillation is not. Atrial flutter is a serious and potentially unstable rhythm of [..]

Rapid variation of signal parameters, such as amplitude, phase, and frequency. Note: Examples of flutter are (a) rapid variations in received signal levels, such as variations that may be caused by atmospheric disturbances, antenna movements in a high wind, or interaction with other signals, (b) in radio propagation, a phenomenon in which nearly al [..]
