    en.wikipedia.org/wiki/Anatomy_of_the_human_heart

    The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...

    en.wikipedia.org/wiki/Situs_solitus

    Anatomically, this means that the heart is on the left with the pulmonary atrium on the right and the systemic atrium on the left along with the cardiac apex. Right-sided organs are the liver , the gall bladder and a trilobed lung as well as the inferior vena cava , while left-sided organs are the stomach , single spleen , a bilobed lung, and ...

    en.wikipedia.org/wiki/Situs_inversus

    If the heart is swapped to the right side of the thorax, it is known as "situs inversus with dextrocardia" or "situs inversus totalis". If the heart remains on the normal left side of the thorax, a much rarer condition (1 in 2,000,000 of the general population), it is known as "situs inversus with levocardia" or "situs inversus incompletus".

    The heart is a muscular organ found in most animals.This organ pumps blood through the blood vessels. [1] Heart and blood vessels together make the circulatory system. [2] The pumped blood carries oxygen and nutrients to the tissue, while carrying metabolic waste such as carbon dioxide to the lungs. [3]

  6. Right axis deviation - Wikipedia

    en.wikipedia.org/wiki/Right_axis_deviation

    The apex of the heart is normally orientated towards the left. A more vertical orientation of the heart, shifts the axis to the right. Physiologically, this can occur in tall and thin individuals. [16] Pathologically, conditions such as a left-sided pneumothorax and lung hyperinflation (e.g. COPD) [17] can

  7. Electrocardiography - Wikipedia

    en.wikipedia.org/wiki/Electrocardiography

    The normal QRS axis is generally down and to the left, following the anatomical orientation of the heart within the chest. An abnormal axis suggests a change in the physical shape and orientation of the heart or a defect in its conduction system that causes the ventricles to depolarize in an abnormal way. [50]
