There are children who are born into the world and then there are some who are afflicted with heart defects occurring due to rheumatic fever. This may be due to a virus. Whenever they exert themselves more than they can, their hearts go into arrhythmias and they can die at any moment. One wonders how lucky we are having pacemakers and defibulators around to keep the heart beating the way it should.
Today the child has a choice of keeping a defibulator on but there are moments when the heart skips a beat and one is not sure when that will happen. Often it can happen if there is too much exertion made on the heart. Stress can also tick off the irregularity.
And the child can have invasive surgery done to through the vena cava to deaden the tissue around the part of the heart cause the irregularity thus permitting a normal rhythm. It is up to the family to decide what to do, as there are risks on both sides. But with the surgery done on the defective part at least the patient does not have to return to the hospital each time to check the abnormal heart beat that comes up now and then. One hopes that the tissue, which is deadened through the vena cava, is not overly extensive to traumatize the effective working of the remaining heart muscle. There is the added stress to the child wanting a normal carefree life and to the parents wanting the child to outgrow the defect.
