Symptoms and Diagnosis of Heart Disease
By Richard N. Fogoros, M.D., About.com Guide to Heart Disease
Heart disease can affect the the heart valves, the heart's electrical system, heart muscle itself, the coronary arteries that feed the heart muscle. The following links lead to articles that address the symptoms of various forms of heart disease, and how doctors can tell that heart disease is present.

Coronary Artery Disease and Heart Attacks
Coronary artery disease - the disease of the blood vessels that supply oxygen and nutrients to the heart muscle - is the most common, and most commonly deadly, form of heart disease. Here are several articles that describe coronary artery disease, the medical conditions it can produce, and how it is diagnosed.
- An overview of coronary artery disease
- Coronary artery disease risk factors
- How Coronary Artery Disease is Diagnosed
- The causes of chest pain
- Unstable angina
- Sudden death after heart attacks
- Electrocardiogram (ECG or EKG)
- Cardiac catheterization and coronary angiography
- The cardiac stress test
- Noninvasive testing for coronary artery disease
- Thallium and Cardiolyte scans
- EBT (ultrafast CT) scans
- Calcium Scores
- Multislice CT scans
- Cardiac syndrome X
Heart Failure

Heart Rhythm Problems
It's with you your entire life, yet you probably don't notice it much: your heartbeat. When normal, the heartbeat is nice and regular, and has just the right rate. But when things aren't quite right -- when the heartbeat is too fast or too slow, or just too irregular -- it's known as a cardiac arrhythmia (heart rhythm problem), which is among the most common of the heart disorders. [p]Most people, in fact, have occasional cardiac arrhythmias. The significance of cardiac arrhythmias can vary tremendously. Many arrhythmias are completely benign, while others are extremely dangerous and life-threatening.

Congenital Heart Diseases
Congenital heart diseases are an assortment of cardiac problems that are present at birth.
Other Heart Diseases
The following articles describe various heart disorders, such as heart valve disease, pericardial disease, and the dysautonomias.
