Heimlich valve: The flutter valve functions by allowing only outwards airflow from the body of the patient. Photo depicting a Heimlich valve. The construction of the flutter valve enables it to function as a one-way valve allowing airflow, or the flow of a fluid, in only one direction along the drainage tube.
"Heart flutter", an abnormally rapid heartbeat: Atrial flutter, a common abnormal heart rhythm; Ventricular flutter, a tachycardia affecting the ventricles with a rate over 250-350 beats/min; Flutter valve, a one-way valve used in respiratory medicine to prevent air from travelling back along a chest tube
Mitral regurgitation, also known as mitral insufficiency or mitral incompetence, is the backward flow of blood from the left ventricle, through the mitral valve, and into the left atrium, when the left ventricle contracts, resulting in a systolic murmur radiating to the left armpit.
Flutter-tonguing is a wind instrument tonguing technique in which performers flutter their tongue to make a characteristic "FrrrrrFrrrrr" sound. The effect varies according to the instrument and at what volume it is played, ranging from cooing sounds on a recorder to an effect similar to the growls used by jazz musicians.
Duckbill valves attached to the hood and shoulders of a Soviet "GP" professional dry suit. Also known as a spear valve or flutter valve, this automatic device serves as a gas exhaust valve on the inside of some twin-hose diving regulators and as an excess gas release valve on the outside of certain mid-twentieth-century dry diving suits.
Although often regarded as a relatively benign heart rhythm problem, atrial flutter shares the same complications as the related condition atrial fibrillation.There is a paucity of published data directly comparing the two, but overall mortality in these conditions appears to be very similar.
Atrial flutter is when the atria repeatedly contract at really high rates, usually due to an underlying condition combined with premature atrial contraction. Faster atrial contraction in turn increases the number of ventricular contraction, which can cause shortness of breath, chest pain, dizziness, and nausea in certain people.
Musical symbols are marks and symbols in musical notation that indicate various aspects of how a piece of music is to be performed. There are symbols to communicate information about many musical elements, including pitch, duration, dynamics, or articulation of musical notes; tempo, metre, form (e.g., whether sections are repeated), and details about specific playing techniques (e.g., which ...
