types congenital heart defects

The heart may have a valve that does not function properly. This results in heart murmur that can be detected by the stethosco..

The defect, which arises due to the irregularity in the arrangement of atoms or ions are called point defects. Point defects are of three types: Stoichiometric defects Non-stoichiometric defects Impurity defects..

The heart beat results in electropotential differences spreading over the heart muscles. These follow a specific pattern. Any change in the pattern indicates an abnormality. The pattern can be recorded using an electrocardiograph. The recorded pattern is called the electro..

The Heart Beat - The heart beat results in electropotential differences spreading over the heart muscles. These follow a specific pattern. Any change in the pattern indicates an abnormality. The pattern can be recorded using an electrocardiograph. The recorded pattern ..

This type of defect is present in those compounds which have Low co-ordination number. Large difference in size of anion and cation. Examples: AgCl, AgBr, AgI and Z..

If imperfections in the crystal are such that the ratio between the anions and cations remain same as represented by the molecular formula, the defect is called a stoichiometric defect. There are three types of stoichiometric defects: Schottky defect Fre..

In in ionic crystal of the type A + B - , equal number of anions and cations are missing from the lattice sites so that electrical neutrality is maintained it is called schottky defect. fig 2.29 - Schottky defect..

According to third law of thermodynamic it is only at OK that true crystals passes perfect order of arrangement of atoms in pure crystals. But with rise in temperature some derivations from complete order takes place. Presence of impurities also adds to disorder. "Any departure from perfectly order..

Heart Lung Machine - Before surgeons can perform open-heart surgery or heart transplants or even to correct a simple heart defect, they have to be able to open up the heart and expose the chambers. To enable this, circulation and respirati..
