To diagnose a conduction disorder, your doctor will ask about your medical history, any signs and symptoms, and your family’s medical history, and he or she will perform a physical exam. Your doctor may also recommend tests to look at your heart’s electrical activity and structure and to determine if you have genetic changes that may signal a conduction disorder.

Bleeding disorders can be inherited, or they can be acquired, meaning you develop them during your lifetime. Acquired bleeding disorders are more common than inherited bleeding disorders.

Your doctor will diagnose sarcoidosis based on your symptoms, a physical exam, imaging tests, or a biopsy of an affected organ. The doctor will also do tests to rule out other diseases that have similar signs and symptoms.

The main types of arrhythmia are bradyarrhythmias; premature, or extra, beats; supraventricular arrhythmias; and ventricular arrhythmias.

Risk factors for VTE include a history of a previous VTE event; surgery; medical conditions such as cancer or spinal cord injury; pregnancy; paralysis or long periods of immobilization; specific genes; and certain circumstances related to age, race, and sex. In most cases of VTE, there is more than one risk factor involved. The more risk factors you have, the greater the chance you have of developing VTE.

Sleep plays a vital role in good health and well-being throughout your life. The way you feel while you are awake depends in part on what happens while you are sleeping. During sleep, your body is working to support healthy brain function and maintain your physical health. In children and teens, sleep also helps support growth and development. Getting inadequate sleep over time can raise your risk for chronic health problems. It can also affect how well you think, react, work, learn, and get along with others. Learn how sleep affects your heart and circulatory system, metabolism, respiratory system, and immune system and how much sleep is enough.

Vasculitis occurs when your immune system injures your blood vessels by mistake. What causes this to happen is not fully known, but when it occurs, your blood vessels become inflamed and can narrow or close off. Rarely, the blood vessel wall may weaken, causing it to expand or bulge. This bulge is known as an aneurysm.

VTE occurs in the veins that carry blood to your heart. Blood clots can develop in veins damaged by surgery or trauma, or a result of inflammation in response to an infection or injury.
