Onset may be rapid (acute) or more gradual (subacute). Signs of<unk>  typically include those of cardiogenic shock including shortness of breath, weakness, lightheadedness, cough and those of Beck's triad e.g. jugular vein distention, quiet heart sounds and hypotension. Other symptoms may relate to the underlying cause. Other general signs of shock (such as fast heart rate, shortness of breath and decreasing level of consciousness) may also occur. However, some of these signs may not be present in certain cases. A fast heart rate, although expected, may be absent in people with uremia and hypothyroidism.
