Bradycardia

Bradycardia is a slower than normal heart rate. The adult heart (at rest) beats at about 60 to 80 beats per minute. 55 to 60 beats per minute would be considered bradycardia for an adult. Infants, however, have a much higher at rest heart rate (110 to 130 beats per minute), thus, bradycardia in infants would be a rate below 100 beats per ...

Thrombocytopenia

Thrombocytopenia is defined as an abnormal reduction in platelet count leading to an increased tendency to bruise or bleed. Platelets, also known as thrombocytes, are the tiny cells in the blood that are responsible for blood clotting. The blood usually contains about 140,000 to 440,000 platelets per microliter. Bleeding can occur with ...

Avian Influenza

Avian influenza (AI), commonly called bird flu, is an infectious viral disease of birds. Most avian influenza viruses do not infect humans; however some, such as H5N1, have caused serious infections in people. The majority of human cases of H5N1 infection have been associated with direct or indirect contact with infected live or dead poultry. ...
