Heart The human heart The heart is a muscular organ in most animals, which pumps blood through the blood vessels of the circulatory system.[1] Blood provides the body with oxygen and nutrients, as well as assists in the removal of metabolic wastes. In humans, the heart is located between the lungs, in the middle compartment of the chest.[3] In humans, other mammals, and birds, the heart is divided into four chambers: upper left and right atria; and lower left and right ventricles.[4][5] Commonly the right atrium and ventricle are referred together as the right heart and their left counterparts as the left heart. Fish, in contrast, have two chambers, an atrium and a ventricle, while reptiles have three chambers.[5] In a healthy heart blood flows one way through the heart due to heart valves, which prevent backflow.[3] The heart is enclosed in a protective sac, the pericardium, which also contains a small amount of fluid.

Charcot-Marie-Tooth disease is a sensorineural peripheral polyneuropathy. The association between Charcot-Marie-Tooth syndrome and cardiac involvement is controversial. Although patients with this disease may have cardiac conduction abnormalities, such abnormalities are often not recognized. Continue reading

Abstract Background: The frequency of cardiac rhythm abnormalities and their risk factors in community-dwelling adults are not well characterized. Methods: We determined the frequency of rhythm abnormalities in the UK Biobank, a national prospective cohort. We tested associations between risk factors and incident rhythm abnormalities using multivariable proportional hazards regression. Continue reading
