Diastolic
|
|
DiastolicThe lower number in a blood pressure reading that indicates the pressure in the heart when the muscle is relaxed (the point of least pressure).
RELATED TERMS--------------------------------------
Blood
The life-maintaining fluid which is made up of plasma, red blood cells (erythrocytes), white blood cells (leukocytes), and platelets; blood circulates through the body's heart, arteries, veins, and capillaries; it carries away waste matter and carbon dioxide, and brings nourishment, electrolytes, hormones, vitamins, antibodies, heat, and oxygen to the tissues.
Heart
The hollow, muscular organ responsible for pumping blood through the circulatory system.
Muscle
Tissue made up of bundles of long, slender cells that contract when stimulated.
SIMILAR TERMS--------------------------------------
Diaschisis
Diaschisis refers to a physiological phenomenon based on reversible depression of functions anatomically or functionally connected to the damaged area.
Diasone sodium
Diasone sodium is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): sulfoxone sodium.
Diastat
Diastat is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): diazepam.
Diastema
Space between teeth.
Diastole
The relaxation phase of the heartbeat.
Diastolic blood pressure
The lowest blood pressure measure in the arteries, which occurs between heartbeats.
Diastolic Pressure
The pressure of the blood in the arteries when the heart is filling. It is the lower of two blood pressure measurements, e.g., 120/80, where 80 is the diastolic pressure.
Diastrophic dwarfism
Short stature, cleft palate, thick pinnae and other features. Autosomal recessive inheritance.
Diastrophic dysplasia
An inherited skeletal disorder involving significantly short stature (dwarfism). Characteristic features at birth include short birth length with short limbs (short-limbed dwarfism), "hitchhiker thumb", and clubfeet. Palatal malformations such as cleft palate or submucous cleft of the palate are present in 50% of patients. There is swelling of the ears in the first days to weeks of life in 80% of children; the swelling then spontaneously subsides but later the ears have a "cauliflower" appearance. Fingers are short and broad and show ulnar deviation (are inclined away from the thumb). The thumb itself has a hitch-hiker-type appearance.
PREVIOUS AND NEXT TERMS--------------------------------------
DNA (Deoxyribonucleic Acid)
A chemical substance in plant and animal cells that tells the cells what to do and when to do it. DNA is the information about what each person inherits from his or her parents.
Dentures
A denture or a complete denture as it is often called, is an appliance that is inserted in the mouth, replaces natural teeth and provides support for the cheeks and lips. Most dentures are made of acrylic and can be fabricated two different ways. A conventional denture is made after all teeth have been extracted and the tissues (gums) have healed. An immediate denture is fabricated and inserted immediately after the teeth are extracted and the tissues are allowed to heal under the denture. An upper denture has acrylic, usually flesh colored, that covers the palate (roof of the mouth). A lower denture is shaped like a horseshoe to leave room for the tongue. The teeth are made of plastic, porcelain or a combination thereof. Dentures can be fabricated to fit over endodonticly treated teeth (See "Root Canals") and a complete denture can be attached to implants (See "Implants") to allow for a more secure fit of the appliance. Dentures over a normal course of time will wear and need to be replaced or relined in order to keep the jaw alignment normal. The alignment will slowly change as the bone and gum ridges recede or shrink due to the extraction of the teeth. Regular dentist examinations are still important for the denture wearer so that the oral tissues can be checked for disease or change. See also "Partial Dentures."
Decisional Incapacity
A condition in which a patient is unable to understand his or her choices or declare personal wishes about his or her care.
Diastolic Pressure
The pressure of the blood in the arteries when the heart is filling. It is the lower of two blood pressure measurements, e.g., 120/80, where 80 is the diastolic pressure.
Diastolic
Dilated cardiomyopathy
A disease of the myocardium (heart muscle) that causes the heart cavity to become stretched and enlarged, and the pumping capacity of the heart is reduced.
Dilatation
The increase in size of a blood vessel.
DNR Order (Do Not Resuscitate Order)
An advanced directive that means no CPR is to be done when the heart and lungs stop.
Donor
A person who gives an organ, tissue or blood to another person. A compatible donor is a person who has the same tissue and blood types as the person who receives the organ, tissue or blood.
D-dimer
A fragment produced during the degradation of a clot. The D here stands for domain. Dimer indicates two identical units, in this case two identical domains. D-dimer result from complete breakdown of the clot. Monoclonal antibody to the D-dimer fragment provide the basis for the main methods of detecting it. The presence of D-dimers in the blood is a reliable clue that clotting has begun. Sometimes written d-dimer or D-Dimer. Pronounced deemer.
