Systole | contractive phase (120/) |
Diastole | relaxation phase (/80) |
SA | sinoatrial node natural pacemaker of the heart |
AV | atrioventricular node carries electrical signal |
NSR | normal sinus rhythm (normal electrical activity) |
Arrhythmias | deviation of electrical signal or abnormal rhythm |
Bundle of His | (atroventricular bundle) in the interatrial septum and its right and left bundle branches transmit the impulse to the Purkinje fibers in the right and left ventricles |
Purkinje fibers | receive stimulation from Bundle of His and cause ventricles to undergo electrical changes that signal contraction to force blood out to the pulmonary arteries and the aorta |

Claudication | cramp-like pains in the calves caused by poor circulation |
Dyspnea | difficult and/or painful breathing |
Edema | abnormal accumulation of fluid in interstitial spaces of tissues |
Bruit | abnormal sound (blowing, whistling) heard when an artery is ascultated (act of listening for sounds made by body organs) |
Pallor | paleness of skin and/or mucous membranes |
Palpitations | pounding or racing of the heart |
Pulmonary congestion | excessive amount of blood in the pulmonary vessels |
SOB | shortness of breath |
Syncope | fainting or loss of consciousness |
Thrill | fine vibration felt by the examiner on palpation |
Palpation | examine by touch |
Coarctation of aorta | localized narrowing of the aorta |
PDA | (patent ductus arteriosus) abnormal opening between the pulmonary artery and the aorta |
ASD | atrial septal defect |
VSD | ventricular septal defect |
Tetralogy of Fallot | congenital anomaly that consists of four defects |
AS | (aortic stenosis) narrowing of the aortic valve |
MS | (mitral stenosis) narrowing of the valve between the left atrium and left ventricle |
TS | (tricuspid stenosis) narrowing of the tricuspid valve |
MR | (mitral regurgitation) backflow of blood from the left ventricle into the left atrium |
MVP | protrusion of one or both cusps of the mitral valve back into the left atrium |
Orthopnea | condition in which a person must sit or stand to breathe comfortably |
Valvulitis | inflammatory condition of a valve |
Infarction | tissue death |
Arrhythmia | abnormal variation from the normal heartbeat rhythm (dysrhythmia) |
Ectopic beats | heartbeats that occur outside of a normal rhythm |
Angina pectoris | chest pain that is often accompanied by SOB and a sensation of impending doom |
CAD | (coronary artery disease) accumulation and hardening of plaque in the coronary arteries that eventually can deprive the heart muscle of oxygen, leading to angina |
MI | (myocardial infarction) cardiac tissue death that occurs when the coronary arteries are occluded by atheroma (fat or lipids on the wall of an artery) or a blood clot |
Cardiac tamponade | compression of the heart caused by fluid in the pericardial sac |
Cardiomyopathy | progressive disorder of the ventricles of the heart |
HF | (heart failure) inability of the heart to pump blood efficiently |
Endocarditis | inflammation of the endocardium |
Pericarditis | inflammation of the pericardium |
Arteriosclerosis | arterial walls become thickened and lose their elasticity WITHOUT the presence of atheromas |
Atheroscelrosis | medium and large arteries have atheromas, which reduce or obstruct blood flow |
Aneurysm | localized dilation of an artery caused by a congenital or acquired weakness in the wall of the vessel |
Hemorrhoid | varicose condition of the external or internal rectal veins |
Hypertension | HTN high or elevated blood pressure |
Hypotension | below normal blood pressure |
Peripheral arterial occlusion | blockage of blood flow to the lower extremities |
PVD | (peripheral vascular disorder) any vascular disease limited to the extremities |
Thrombophlebitis | inflammation of either deep or superficial veins |
Varicose veins | elongated, dilated superficial veins with incompetent valves that permit reverse blood flow |
Vasculitis | inflammation of the blood vessels |
PET | (positron emission tomography) computerized nuclear medicine procedure that uses inhaled or injected radioactive substances to help identify how much a patient will benefit from revascularization procedures |
Radiography | x-rays |
Phlebography | x-rays of a vein after the introduction of a contrast dye |
Cardiac catheterization | threading of a catheter into the heart to collect diagnostic infomration about structures in the heart, coronary arteries and great vessels |
Swan-Ganz catheter | long, thin cardiac catheter with a tiny balloon at the tip used to determine left ventricular function by measuring pulmonary capillary wedge pressure |
ECG/EKG | (electrocardiography) recording of electrical impulses of the heart [the record is called an electrocardiogram] |
