cardio-, cardi-, card-

(Greek: heart, pertaining to the heart)

apexcardiogram, apex cardiogram (ACG)
1. A graphic recording of the movements of the chest wall produced by the apex beat of the heart.
2. A graphic recording of ultra-low-frequency precordial chest-wall movements.
apexcardiography (s) (noun), apexcardiographies (pl)
A noninvasive graphic recording of the cardiac pulsations from the region of the apex, usually of the left ventricle, and resembling the ventricular pressure curve.
atelocardia
The congenitally incomplete development of the heart.
auxocardia
ballistocardiogram
A record of the body's recoil caused by cardiac contraction, the ejection of blood into the aorta, and ventricular filling forces; has been used as a basis for calculating the cardiac output in mankind, but its lack of accuracy and reproducibility has caused it to be discarded.
ballistocardiograph (s) (noun), ballistocardiographs (pl)
1.The graphic recording of movements of the body imparted by ballistic forces or the cardiac contraction and ejection of blood, ventricular filling, acceleration, and deceleration of blood flow through the great vessels.

These minute movements or ballistocardiographs are amplified and recorded on a moving paper chart after being translated into an electrical potential by a pickup device.

2. An instrument for recording the movements of the body caused by ejection of blood from the ventricles at each beat of the heart.
ballistocardiographic (adjective), more ballistocardiographic, most ballistocardiographic
1. A reference to an instrument for recording the movements of the body which are caused by rejection of blood from the ventricles at each beat of the heart.
3. A descriptive term for the study and interpretation of ballistocardiograms.
bathycardia
A condition in which the heart occupies a lower position than normal but is fixed there, as distinguished from cardioptosia (a condition in which the heart is unduly movable and displaced downward).
bicardiogram
The composite curve of an electrocardiogram representing the combined effects of the right and left ventricles.
brachycardia
bradycardia
A slow heart rate, usually defined as less than 60 beats per minute.

This can occur in normal people, particularly during sleep; trained athletes also usually have slow pulse and heart rates.

bradycardiac
Relating to, or characterized by, bradycardia (slowness of the heart beat).
bradycardiaphobia (s) (noun), bradycardiaphobias (pl)
A fear of one's heart beating extremely slow and therefore he or she being close to death: Pearl was told by her doctor that having bradycardiaphobia was not necessarily deadly, however it might be a secondary reaction that sometimes follows an initial phase of rapid heartbeats after a blood-injury.
bradycardic
A reference to bradycardia or an agent that acts to slow the pulse rate.
bradytachycardia
Alternating attacks of bradycardia and tachycardia, as may occur in sick sinus syndrome.

A cross reference of another word group that is related to: "heart": cor-, cord-.
