This point is called decompensation. Also by valve disorders, myocarditis, hypertension and severe rhythm disorders. Morphine inhibits the respiratory control center. Respiratory frequency is decreased. Digitalis improves the contraction force of the heart.
Diuretics decreases circulatory volume.
Nitrobaat and Cedocard decreases pre-load by dilating the venous bloodvessels. Nipride, Minipress and Adalat decreases after-load by decreasing the peripheral vascular resistance. A tamponade is a disturbed pump function of the heart as a result of an increased intrapericardial pressure. This can be caused by a ventricular perforation after a myocard infarction, in the acute phase of pericarditis or after a thoraxtrauma. A thrombus can be caused by the inactivity of muscles, or on the rough surface of the place of an infarction.
