Hemodynamic and mechanical determinants of myocardial O(2) consumption in normal human heart: Effects of dobutamine
A study investigated the relationship of myocardial oxygen consumption (MVo2) to its potential hemodynamic and mechanical determinants at rest and during infusion of dobutamine. Results indicate that MVo2 is related to systolic pressure-volume area and that dobutamine causes decreased efficiency of...

| Zusammenfassung: | A study investigated the relationship of myocardial oxygen consumption (MVo2) to its potential hemodynamic and mechanical determinants at rest and during infusion of dobutamine. Results indicate that MVo2 is related to systolic pressure-volume area and that dobutamine causes decreased efficiency of contraction. |
