cardio-, cardi-, card-

1. A radiographic diagnostic study of the heart in which valves and vessels on the left side are examined via x-ray and fluoroscopy following the introduction of a contrast media.
2. Examination of the left side of the heart and associated blood vessels using x-rays following the injection of a radiopaque substance.

That part of the bicardiogram (combined effects of the right and left ventricles or muscular chambers of the heart), or a normal curve, which is the effect of the left ventricle.

1. A reference to a fatty heart.
2. Denoting a person suffering from fatty degeneration of the heart.

Use of graphic tracings reflecting the mechanical effects of the heartbeat; such as, the carotid pulse tracing or apexcardiogram.

Phonocardiography is also usually considered a form of mechanocardiography.

The central position of the heart in the chest, as in an embryo.

This position is normal in the fetal (pre-birth) stage, but a malposition (abnormal position) after birth.

1. A double layer of membrane in the developing embryo that attaches the heart to the body wall and the foregut.
2. Epicardium covering the blood vessels which enter and leave the heart.

The dorsal mesocardium connects the heart to the foregut, and the ventral mesocardium connects the heart to the central body wall.

Decreasing heart volume during systolic contraction.

1. Having a heart with one atrium and one ventricle; as in, hemicardia (a congenital malformation of the heart in which only two of the usual four chambers are formed).
2. The presence of only one side of a four-chambered heart.

Heart disease.
