Mechanisms of Cardiogenic and Obstructive Shock
Type | Mechanism | Cause |
|---|---|---|
Obstructive | Mechanical interference with ventricular filling | Tension pneumothorax, vena cava compression, cardiac tamponade, atrial tumor or clot |
Interference with ventricular emptying | ||
Cardiogenic | Impaired myocardial contractility | Myocardial ischemia or myocardial infarction, myocarditis, medications |
Abnormalities of cardiac rhythm | Tachycardia, bradycardia | |
Cardiac structural disorder | Acute mitral or aortic regurgitation, ruptured interventricular septum, prosthetic valve malfunction |
