Common sleep apnea signs and symptoms are snoring or gasping during sleep; reduced or absent breathing, called apnea events; and sleepiness. Undiagnosed or untreated sleep apnea prevents restful sleep and can cause complications that may affect many parts of your body.

Changes to the heart’s tissue and to its electrical signals most often cause atrial fibrillation. When the heart’s tissue or signaling is damaged, the regular pumping of the heart muscle becomes fast and irregular.

The major types of stroke are ischemic (when an artery to the brain becomes blocked) and hemorrhagic (when an artery in the brain leaks blood or breaks open).

In all types of sickle cell disease, at least one of the two abnormal genes causes a person’s body to make hemoglobin S. When a person has two hemoglobin S genes (hemoglobin SS), the disease is called sickle cell anemia. This is the most common and often most severe type of sickle cell disease. Hemoglobin SC disease and hemoglobin S? thalassemia are two other common types of sickle cell disease. Hemoglobin SD and hemoglobin SE are much less common.

It may be possible for your doctor to diagnose your bleeding disorder, its severity, and whether it is inherited or acquired based on your signs and symptoms, risk factors, medical and family history, a physical exam, and blood tests.

Cardiac catheterization takes place in a catheterization laboratory, or cath lab, which is similar to a small operating room. A long thin tube called a catheter is inserted via a needle, guidewire, and sheath into a blood vessel leading to the heart.

El médico puede diagnosticarle sarcoidosis con base en sus síntomas, un examen físico, el diagnóstico por imágenes o la biopsia de un órgano afectado. El médico también realizará pruebas para descartar otras enfermedades que tengan signos y síntomas parecidos.

There are many types of conduction disorders that can occur anywhere along the cardiac conduction system: at the sinoatrial (SA) node, the atrioventricular (AV) node, or the bundle branches. The problem can be with signal generation, how the signal travels through the heart, or both. Disorders can occur on a much smaller level within ion channels in a heart muscle cell that work together to make the heart cell contract.

Difficulty breathing is usually the first symptom of ARDS. Other signs and symptoms of ARDS may vary depending on the underlying cause and how severely you are affected. ARDS may take several days to develop, or it can rapidly get worse. Complications may include blood clots, infections, additional lung problems, or organ failure.

Cystic fibrosis is an inherited disease caused by mutations in a gene called the cystic fibrosis transmembrane conductance regulator (CFTR) gene.
