Patients with severe heart failure are often in very poor physical condition, they are unable to take part in the usual exercise programs, and therefore need an individual approach. Seventeen patients with severe heart failure (ejection fraction 20%) were exposed to 3 types of load for a period of 10 seconds. During each measurement, a continuous, time-synchronized record was taken of the electrocardiogram, and the pulmonary and systemic blood pressures. There were slight changes in the heart rate and systemic blood pressure when comparing resting versus MVC-LEM values. There were much greater and significant changes (P < .01) in the systemic and pulmonary blood pressures when comparing resting versus the Valsalva maneuver or the combination of the MVC-LEM plus the Valsalva maneuver values.
