The Cardiovascular System
| Term | Definition |
|---|---|
| Cardiac | Pertaining to the heart. |
| Cardiologist | One who specializes in heart study. A doctor specializing in heart disease and treatment. |
| pericardial | Pertaining to surrounding the heart. Anatomically refers to the tissue membrane that surrounds the heart, called the pericardium. |
| Epicardium | Upon the heart. Anatomically refers to the thin, most superficial tissue layer of the heart. |
| Myocardial | Pertaining to muscle of the heart. |
| Endocardium | Within the heart. Anatomically refers to the thin tissue layer that lines the interior of the heart. |
| Atrial | Pertaining to the atrium. Anatomically the atria are two of the four chambers within the heart. |
| Ventricular | Pertaining to a ventricle. Anatomically the ventricles are two of the four chambers within the heart. |
| Atrioventricular | Pertaining to an atrium and a ventricle. |
| Aortic | Pertaining to the aorta. Anatomically the aorta is the main artery leading from the heart. |
| Pulmonic | Pertaining to the lungs. |
| Arterial | Pertaining to an artery or arteries. |
| Venous | Pertaining to a vein or veins. |
| Venule | A very small vein. |
| Phlebotomy | The cutting of a vein. Clinically refers to puncture of a vein with a needle for the withdrawal of blood. |
| Phlebitis | Inflammation of a vein. |
| Cardiomyopathy | A disease of heart muscle. |
| Electrocardiogram | A recording of electricity of the heart. Clinically referred to as a ECG (EKG -German form). The electrocardiogram is a graphic tracing of the heart's electrical activity. |
| Echocardiogram | A recording of echoes of the heart. Clinically refers to the use of ultrasonic waves to record the anatomy and motion of the heart. |
| Angiogram | A recording of vessels. Clinically refers to a radiographic procedure in which radiopaque dye is injected into the vasculature for better visualization of the vessels. |
| Intravenous | Pertaining to within a vein. Clinically often refers to a route of medication administration. |
| Perivascular | Pertaining to around a vessel. |
| Bradycardia | A condition of a slow heart (i.e. heart rate) |
| Tachycardia | A condition of a rapid heart. (i.e. heart rate) |
| Systolic | Pertaining to contraction. Clinically refers to the phase of cardiac cycle when the myocardium is contracting. |
| Diastolic | Pertaining to expansion. Clinically refers to the phase of the cardiac cycle when the myocardium is relaxed, allowing the chambers to expand. |
| Asystole | Absence of contraction. Clinically refers to the absence of cardiac activity. |
