The symptoms of pericarditis depend on the type, but may include: 1  high temperature. 2  sweating and chills. 3  breathing problems, such as breathlessness. 4  dry cough. 5  abnormal heart rhythms, such as accelerated heartbeat (tachycardia) 6  sharp and stabbing chest pains. 7  pain radiating into the left shoulder and arm.
Pathophysiology. Rupture of the membranes is the most common cause of oligohydramnios. However, because the amniotic fluid is primarily fetal urine in the latter half of the pregnancy, the absence of fetal urine production or a blockage in the fetus' urinary tract can also result in oligohydramnios.
1 Too low level of amniotic fluid indicates that the placenta is not working to its optimum. 2  It is an indicator of many problems. 3  Low amniotic fluid volume or oligohydramnios can lead to stunted growth, slow heart beat and in the most severe cases even prenatal mortality.
