Terminology
When the wall of the artery weakens, resulting in bulging of the artery when it fills with blood
Aneurysm
Amount of blood pumped every day
1000 gallons
These are the two characteristics that affect the functions of the conduction system
Automaticity and Irritability
A series of radiographs taken after contrast dye is injected into the artery or vein
Angiogram
These are nonmodifiable risk factors for cardiac disease
Family history, age, gender, culture and ethnicity
Abnormal increase in the number of red blood cells
Polycythemia
These structures connect the AV valves to the walls of the heart
Chordae Tendineae
This is where the heartbeat is initiated
SA node (sinoatrial)
Graphic study of the electrical activities of the myocardium
EKG/ECG
Interval between atrial and ventricular repolarization
P-R interval
Abnormal accumulation of fluid in the thoracic cavity
Plueral Effusion
This chamber receives deoxygenated blood from the entire body
Right atrium
4 Parts of the main trunk of the systemic arterial circulation system
Ascending aorta, the arch, thoracic portion of the descending aorta, the abdominal portion of the descending aorta
Proteins that are released into the circulation as a result of damage to the cardiac cells
Serum Cardiac Markers
Supraventricular tachycardia
Decreased blood supply to a body organ or part
Ischemia
The three layers of the heart
Pericardium, myocardium, and endocardium
This is the blood flow pattern
Artery - Arteriole - Capillary - Venule - Vein
Muscle proteins released into circulation after a myocardial injury
Troponins
Treats A-fib in younger patients
Catheter ablation
Discoloration or erythema caused by inflammation.
Rubor
The ribs that the top and bottom of the heart lie between
Beneath 2nd rib and between the 5th and 6th rib
This is the impulse pathway
SA Node - AV Node - Bundle of His - Right and left bundle branches - Purkinje fibers
This restores the heart's normal sinus rhythm by delivering a synchronized electric shock
Cardioversion
Termination of ventricular fibrillation by delivering a direct electrical countershock to the patient's percordium
Defibrillation
