Symptoms involving cardiovascular system
Tachycardia unspecified
- excessive rapidity in the action of the heart.
- Tachycardia; an abnormally rapid heartbeat, usually applied to a heart rate above 100 per minute.
Palpitations
- An unpleasant sensation of irregular and/or forceful beating of the heart.
Undiagnosed cardiac murmurs
Other abnormal heart sounds
Gangrene
- death and decay of body tissue, often occurring in a limb, caused by insufficient blood supply and usually following injury or disease.
- Death of tissue, usually in considerable mass and generally associated with loss of vascular (nutritive) supply and followed by bacterial invasion and putrefaction.
Shock without mention of trauma
Shock unspecified
- a profound hemodynamic and metabolic disturbance characterized by the failure of the circulatory system to maintain adequate perfusion of vital organs; causes inadequate delivery of nutrients and insufficient removal of cellular waste products to and from the tissues.
Cardiogenic shock
- shock reulting from the failure of the heart to maintain adequate output.
- Shock resulting from primary failure of the heart in its pumping function, as in myocardial infarction, severe cardiomyopathy, or mechanical obstruction or compression of the heart.
Septic shock
- shock caused by infection; frequently caused by gram negative bacteria, although some cases have been caused by other bacteria, viruses, fungi, and protozoa; characterized by fever, chills, tachycardia, tachypnea, and hypotension.
Other shock without trauma
- Shock resulting from insufficient blood volume for the maintenance of adequate cardiac output, blood pressure and tissue perfusion.
Enlargement of lymph nodes
- Lymphadenopathy: the abnormal enlargement of lymph nodes.
