For example, a heart attack (myocardial infarction) can cause an abnormal, ineffectual heartbeat (arrhythmia) with very slow, rapid, or irregular contractions of the […]
- Shock, hypovolemic
Shock due to a decrease in blood volume from bleeding, loss of blood plasma through severe burns, or dehydration. Symptoms include dizziness and loss of consciousness.
