Hemodynamic Predictors of Myocardial Oxygen Consumption During Static and Dynamic Exercise

Hemodynamic predictors of myocardial oxygen consumption during static and dynamic exercise.

Hemodynamic predictors of myocardial oxygen consumption (MVO2) during static and dynamic exercise were examined in ten normal subjects. Studies were done under the following circumstances: 1) during upright bicycle exercise at an average heart rate of 147 beats/min, 2) during static exercise with an isometric load in the left hand equal to 17% of the maximal voluntary contraction (MVC), and 3) ...

Effect of propranolol on myocardial oxygen consumption and its hemodynamic correlates during upright exercise.

Measurements were made of heart rate, aortic blood pressure, systolic ejection period/beat, myocardial blood flow, and myocardial oxygen consumption in nine normal young men during three bouts of upright bicycle exercise: 1) at the workload which produced a heart rate of 120 beats/minute, 2) at the higher workload necessary to produce a heart rate of 120 beats/minute after administration of int...

Hemodynamic dependence of myocardial oxygen consumption indexes.

We tested the afterload and contractile state dependency of three indexes of myocardial oxygen consumption (MVO2): total energy requirement (Et), pressure work index (PWI), and pressure-volume area (PVA). MVO2 was measured in seven isolated canine hearts at four or five different end-diastolic volumes at each of three settings of afterload resistance and with the hearts contracting isovolumical...
