Diastolic heart failure is defined as a condition caused by increased resistance to the filling of one or both ventricles; this leads to symptoms of congestion from the inappropriate upward shift of the diastolic pressure-volume relation.
Diagnostic
Diagnostic Criteria for Atopic Dermatitis (AD)
Atopic dermatitis (AD) is an eczematous, highly pruritic chronic inflammatory skin disease. It usually begins early in life and often occurs in people with a personal or family history of asthma and allergic rhinitis.
DSM-IV Diagnostic Criteria for Major Depressive Episode
A. Five (or more) of the following symptoms have been present during the same 2-week period and represent a change from previous functioning; at least one of the symptoms is either (1) depressed mood or (2) loss of interest or pleasure.
Diagnostic Criteria for Disseminated Intravascular Coagulation (DIC)
Disseminated intravascular coagulation is a condition in which small blood clots develop throughout the bloodstream, blocking small blood vessels. The increased clotting depletes the platelets and clotting factors needed to control bleeding, causing excessive bleeding.
ROME II Diagnostic Criteria for Childhood Functional Gastrointestinal Disorders
The diagnosis of a Childhood Functional Gastrointestinal Disorder always presumes the absence of a structural or biochemical explanation for the symptoms.
G1.Vomiting
G1a. Infant Regurgitation
DSM-IV Diagnostic Criteria for Bulimia Nervosa
A. Recurrent episodes of binge eating. An episode of binge eating is characterized by both of the following:
- Eating, in a discrete period of time (e.g., within any 2-hour period), an amount of food that is definitely larger than most people would eat during a similar period of time and under similar circumstances.
- A sense of lack of control over eating during the episode (e.g., a feeling that one cannot stop eating or control what or how much one is eating).
Diagnostic Criteria of Hemorrhage in MRI of the Brain
The imaging characteristics of blood on MRI can be variable:
ROME II Diagnostic Criteria for Functional Bowel Disorders
The diagnosis of a Functional Bowel Disorder always presumes the absence of a structural or biochemical explanation for the symptoms.
ROME II Diagnostic Criteria for Functional Disorders of the Biliary Tract and the Pancreas
The diagnosis of a Functional Disorder of the Biliary Tract and Pancreas always presumes the absence of a structural or biochemical explanation for the symptoms.
E1. Gallbladder Dysfunction
Episodes of severe steady pain located in the epigastrium and right upper quadrant, and all of the following:
- Symptom episodes last 30 minutes or more, with pain-free intervals;
- Symptoms have occurred on one or more occasions in the previous 12 months;
- The pain is steady and interrupts daily activities or requires consultation with a physician;
- There is no evidence of structural abnormalities to explain the symptoms; and
- There is abnormal gallbladder functioning with regard to emptying.
Common Diagnostic Criteria for Left and Right Atrial Abnormalities
Left Atrial Abnormality
- Prolonged P wave duration of >120 msec in lead II
- Prominent notching of the P wave, usually most obvious in lead II, with an interval between the notches of >40 msec (p mitrale)
- Ratio between the duration of the P wave in lead II and the duration of the PR segment of >1.6
- Increased duration and depth of the terminal negative portion of the P wave in lead V1 (the P terminal force) so that the area subtended by it exceeds 0.04 mm-sec (Morris index)
- Leftward shift of the mean P wave axis to between -30 and +45 degrees
