Factors That Cause a Hypoeffective Heart: Any factor

        that decreases the heart’s ability to pump blood causes

        hypoeffectivity.

        Some of the factors that can decrease the heart’s ability
        to pump blood are the following:

             • Increased arterial pressure against which the
               heart  must pump, such as in severe

               hypertension • Inhibition of nervous excitation
               of the heart • Pathological factors that cause

               abnormal heart  rhythm or rate of heartbeat
             • Coronary artery blockage, causing a “heart
               attack”                                                                Figure 3

             • Valvular heart disease
             • Congenital heart disease

             • Myocarditis, an inflammation of the heart muscle
             • Cardiac hypoxia[1].
