Hyperdynamic circulation
Hyperdynamic circulation (pronounced: hi-per-dy-nam-ic cir-cu-la-tion) is a medical term used to describe a state of increased blood flow through the body's circulatory system.
Etymology
The term is derived from the Greek words 'hyper' meaning 'over' and 'dynamis' meaning 'power'. In medical terminology, it is used to describe an overactive or excessively powerful circulatory system.
Definition
Hyperdynamic circulation is characterized by an increase in cardiac output, heart rate, and blood volume, leading to an increase in the body's blood flow. This condition is often associated with certain diseases and conditions such as sepsis, liver cirrhosis, and anemia.
Symptoms
Symptoms of hyperdynamic circulation may include tachycardia (an abnormally rapid heart rate), palpitations, and a bounding pulse. In severe cases, it can lead to heart failure due to the increased workload on the heart.
Diagnosis
Diagnosis of hyperdynamic circulation is typically made through physical examination and medical imaging tests such as echocardiography. Blood tests may also be used to identify underlying conditions that may be causing the hyperdynamic circulation.
Treatment
Treatment for hyperdynamic circulation typically involves addressing the underlying cause. This may include medications to control heart rate and blood pressure, or treatment for conditions such as sepsis or liver cirrhosis.
