Definition Cardiac output refers to the volume of blood ejected by the left ventricle, and is usually expressed in milliliters per minute. Cardiac output is therefore the mathematical product of heart rate (contractions per minute) and stroke volume (ml of blood ejected per contraction). In a ...
Usually cardiac output is regulated mainly by the tissues, each regulating its own blood flow, cardiac output being the sum of the flows through all the peripheral tissues. The normal human heart under resting conditions can pump perhaps 12-15 l/min., and when stimulated by the autonomic syste...

Normal Output It’s different for different people, depending on their size. Usually, an adultheartpumps about 5 liters ofbloodper minute at rest. But when you run orexercise, your heart may pump 3-4 times that much to make sure your body gets enough oxygen and fuel. ...
The method is usually expressed in the sampled-time domain and requires judiciously placed electrodes on the torso in order to comprise all the information contained in the cardiac electrical field. Theoretically, orthogonal leads X, Y, and Z should be sufficient to completely characterize this ...
This did not preserve cardiac function as expressed by LV ejection fraction after 3 weeks follow-up, which makes the MI-R model suitable to study hypothesized functional effects of novel therapeutic interventions. In addition, both infarction models caused an obvious local and systemic inflammatory ...
For example, although commonly used inotropes such as dobu- tamine increase cardiac output, treatment is usually associated with severe side effects such as arrhythmias and hypotension4,5. Consequently, there is a largely unmet demand for new pharmacological therapies for heart disease and heart ...
distribution and burden of ischemia detected, usually combined with a composite score of clinical risk factors or inferred from an expert clinical impression—while this has proven to be a generally successful model from a statistical viewpoint, it is arguably relatively crude at the individual ...
In terms of signal intensity, these 50 microRNAs accounted for approximately 80% of all the combined microRNAs expressed in the heart (Figure 2B and Table 1), indicating that they are cardiac-enriched miRNAs. When compared with U6-snRNA gene, which is a gene that was used as a reference, ...
