Types of Heart Disease
Diseases that affect the heart muscle itself

A structural or functional disease of the heart muscle 
A condition in which the heart becomes weakened and enlarged and its pumping capacity is reduced
A condition in which the heart muscle is thickened and so strong that it does not relax enough after contraction to fill the heart with blood and so its pumping capacity is reduced
A condition in which the heart beats normally but the stiffness of the walls of the heart chambers prevent it from stretching and filling with blood heart 

Inflammation of the myocardium, the muscular tissue of the heart
 * * * * * 
Diseases that affect the heart chambers 

A condition in which the heart is not able to adequately pump blood to the lungs and other parts of the body
A weakness of the heart's right pumping chamber caused by disease of the lungs or blood vessels in the lungs   
 * * * * * 
Diseases that affect the heart valves (valvular heart disease)

Abnormal heart sounds, sometimes caused by abnormal function of a heart valve
A condition in which the valve between the left ventricle and the aorta is narrowed
Abnormal leakage of blood backwards from the aorta through a weakened aortic valve into the left ventricle
A relatively benign condition in which the flaps of the mitral valve are too large and cannot close properly, allowing a small amount of blood to leak backward
A condition in which the valve between the left atrium and the left ventricle is narrowed
Abnormal leakage of blood backward through the mitral valve from the left ventricle to the left atrium
A condition in which the outflow of blood from the right ventricle to the lungs is obstructed
condition in which the pulmonary valve is not strong enough to prevent the flow of blood backwards into the right ventricle
Changes in the myocardium or scarring of the heart valves cause by rheumatic fever
The narrowing of the opening of the tricuspid valve
A condition caused by the failure of the tricuspid valve to close properly during systole (contraction) so that some blood passes from the right ventricle to the right atrium, the opposite of the normal direction
* * * * *
Diseases of the arteries and veins

Pain or discomfort in the chest when part of the heart is not receiving enough blood
Angina that is "predictable"; for example, with exercise or under stress
Pain that occurs at rest, or new pain with exercise, or pain that is more frequent or longer
Pain that comes in recurring intervals while at rest
A disease in which "plaque"  (fatty deposits) clogs and narrows arteries, restricting blood flow
Atherosclerosis of the coronary (heart) arteries
Damage or death to a part of the heart muscle because of a blocked blood supply to that area
A cardiovascular disease in which blood pushes against artery walls with greater force than normal, all or most of the time, usually because the arteries are inflexible or too narrow
Narrowing or blockage of vessels that carry blood to the extremities such as arms and legs
A painless condition in which the heart muscle does not receive enough oxygen-rich blood to meet its needs
* * * * *
Diseases that affect the electrical system (arrhythmias)

Heart rhythm in which the atria (upper heart chambers) are contracting rapidly and irregularly
Heart rhythm in which the atria are contracting rapidly but but regularly
A genetic disease that is characterised by abnormal electrocardiographic findings and an increased risk of sudden cardiac death
A form of heart block which causes a delay in the signal from the atria to the ventricles
disorder in which the electrical impulses that cause the heart to beat are slowed or blocked along the pathway between the upper and lower chambers of the heart
A syndrome in which the QT interval, which is the amount of time it takes for the ventricles to contract and then relax, is longer than normal
A specfic type of supraventricular tachycardia that occurs when there are two ore more different sites of in the upper heart (atria) that are sending competing signals to the lower heart
Sudden onset of a series of rapid heart beats originating above the lower chambers of the heart (ventricles)
A kind of premature or irregular heart beat (arrhythmia) which starts in the upper two chambers of the heart (atria)
A common abnormal heart rhythm, often called palpitations, skipped beats or irregular beats, in which the heart beat is initiated by the lower chambers (ventricles) rather than by the sinoatrial node, the heart's normal pacemaker (heartbeat initiator)
A collection of heart rhythm disorders (arrhythmias) caused by a malfunction of the sinus node (the heart's own pacemaker)

Sinus tachycardia 

Heart rhythm which is formed in the normal manner but which is faster than normal     


Heart rhythm which is formed in the normal manner but which is slower than normal
Series of rapid heartbeats originating above the lower chambers of the heart (ventricles) that can cause the heart to beat very rapidly or erratically and may lead to inadequate blood supplies to the body  
A condition in which the ventricles contract in a rapid and unsynchronized way and no blood is being pumped throughout the body and which requires immediate correction
A rapid heart rate that originates in the ventricles and which is dangerous and requires immediate correction
A syndrome of pre-excitation of the ventricles of the heart due to an accessary pathway known as the"bundle of Kent."  This pathway is an abnormal electrical communication between the atria and the ventricles.

Diseases of the heart lining

An inflammation of the endocardium, the membrance that lines the interior cavities of the heart
An inflammation of the pericardium, the double-walled sac that contains the heart and the roots of the vessels close to the heart
