2.2.6 Low output failure
In the majority of animals with heart failure, a stable equilibrium is reached in which homeostatic mechanisms result in compensation and the maintenance of an adequate cardiac output. However, eventually the compensatory mechanmay not be sufficient to maintain the required cardiac output and signs of cardiac insufficiency such as weakness and weight loss develop. This is known as low output or decompensated failure. This may also occur when cardiac disease develops rapidly, resulting in acute clinical signs.
