| diastole | to expand; period during the cardiac cycle (complete heart beat) when blood enters the relaxed ventricles from the atria |
| aortogram | x-ray image of the aorta |
| saccular aneurysm | a sac-like bulge on one side of an artery |
| fusiform aneurysm | a spindle-shaped bulge of an artery |
| NSR | normal sinus rhythm |
| congenital anomaly of the heart | malformations of the heart that are present at birth (congenital = born with; anomaly = irregularity) |
| SV | stroke volume |
| CABG | coronary artery bypass graft |
| palpitation | subjective experience of pounding, skipping, or racing heartbeat |

| ejection fraction | Measurement of the volume percentage of the left ventricular contents ejected with each contraction |
| ventriculogram | x-ray image of the ventricles |
| systemic circulation | circulation of blood throughout the body via arteries, arterioles, capillaries, venules, and veins to deliver oxygen and nutrients to body tissues |
| diuretic | drug that increases the secretion of urine; commonly prescribed in treating hypertension |
| PCI | percutaneous coronary intervention |
| MUGA | multiple-gated acquisition (scan) |
| MI | myocardial infarction |
