types of heart defects

Types of defects in Crystals - 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 defect..

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 shown by highly ionic compounds which have High coordination number Cations and anions of similar sizes Examples: KCl, NaCl, KBr and Cs..

Stoichiometric Defects - 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 def..

If an ion is missing from its lattice site (causing a vacancy or a hole there) and it occupies the interstitial site so that electrical neutrality as well as stoichiometry of the compound are maintained. This type of defect is called Frenkel defect. Since the size of ..

Defects in Crystals - 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. "An..

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 respiration are maintained by the ..
