cardio-, cardi-, card-

The record obtained by electrocardiophonography (a method of electrically recording the heart sounds).

This record provides information about the part of the heart that triggers each heartbeat (the pacemaker), the nerve conduction pathways of the heart, and the rate and rhythm of the heart.

A reference to a method of electrically recording the sounds of the heart.

1. An instrument that permits direct visual inspection of the interior of the heart.
2. An instrument that permits continuous electrocardiographic observation of the heart's action during an operation.

An acute viral disease characterized by inflammation and degeneration of skeletal and cardiac muscle and lesions of the central nervous system.

Electrocardiography with the exploring electrode within the chambers of the heart.

The surgical removal of the epicardium, usually performed in constrictive pericarditis to permit greater diastolic filling of the heart.

The epicardium is the inner layer of the pericardium, a conical sac of fibrous tissue that surrounds the heart and the roots of the great blood vessels.

The pericardium has outer and inner coats. The outer coat is tough and thickened, loosely cloaks the heart, and is attached to the central part of the diaphragm and the back of the sternum (breastbone).

The inner coat is double with one layer closely adherent to the heart while the other one lines the inner surface of the outer coat with the intervening space being filled with fluid.

This small amount of fluid, called the pericardial fluid, acts as a lubricant to allow normal heart movement within the chest.

A record of the extent of movement or the amount of work done by the heart.

A medical instrument that measures the mechanical, or work, force of cardiac contractions and the amount of blood passing through the heart during a specified period by measuring the recoil of the body as blood is pumped from the ventricles

An instrument for recording working activities of heart beats.

A revisional procedure of the esophagus and cardiac end of the stomach.
