The cause of cardiomyopathy, a thickening or enlarging of the heart muscle, may depend on the type: 1  Dilated cardiomyopathy. 2  The cause of this most common type of cardiomyopathy often is unknown. 3  It may be caused by reduced blood flow to the heart (ischemic heart disease), infections, toxins and certain drugs.ommon causes of abnormal heart rhythms (arrhythmias) or conditions that can lead to arrhythmias include: 1  Heart defects you're born with (congenital heart defects). 2  Coronary artery disease. 3  High blood pressure. 4  Diabetes. 5  Smoking.
If the diatomic molecule consists of atoms from two different elements, then it is a heteronuclear diatomic molecule. There are seven elements that naturally occur as homonuclear diatomic molecules in their gaseous states: hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine. Bromine and iodine need slightly higher temperatures than room temperature to occur as gaseous diatomic molecules.
A homonuclear diatomic molecule is made of two atoms of the same element that are joined together by a chemical bond. These molecules usually exist in the gaseous phase. Some of the gases that exist as diatomic molecules at room temperature and at atmospheric pressure are H 2, N 2, O 2, F 2 and, Cl 2.
