| REFERS TO THE NARROWING OF A VALVE | MURMURS |
| EXTRA HEART SOUND (S3, S4) THAT SOUND LIKE A RACING HORSE | GALLOP RHYTHM |
| VALVE THAT PREVENTS THE BACKFLOW OF BLOOD INTO THE LEFT VENTRICLE | AORTIC VALVE |
| HEART SOUND CREATED BY THE CLOSURE OF THE AV VALVES AT THE BEGINNING OF VENTRICULAR CONTRACTION | S1 |
| ENTRANCE VALVE THAT SEES ONLY OXYGENATED BLOOD | BICUSPID VALVE |
| VALVE THAT PREVENTS THE BACKFLOW OF BLOOD FROM THE LEFT VENTRICLE | BICUSPID VALVE |
| HEART SOUND CREATED BY THE CLOSURE OF THE SEMILUNAR VALVES AT THE BEGINNING OF VENTRICULAR RELAXATION | S2 |
| EXIT VALVE THAT SEES ONLY UNOXYGENATED BLOOD | PULMONIC VALVE |
| VALVE THAT PREVENTS THE BACKFLOW OF BLOOD FROM THE PULMONARY ARTERY | PULMONIC VALVE |
| SEMILUNAR VALVE THROUGH WHICH BLOOD LEAVES THE LEFT VENTRICLE | AORTIC VALVE |
| ABNORMAL HEART SOUNDS CAUSED BY VALVULAR DISEASE | MURMURS |
| ENTRANCE VALVE THAT SEES ONLY UNOXYGENATED BLOOD | TRICUSPID VALVE |
| LIFE-THREATENING DYSRYTHMIA THAT CAUSES THE VENTRICULAR MYOCARDIUM TO QUIVER IN AN UNCOORDINATED AND INEFFECTIVE WAY | VENTRICULAR FIBRILLATION |
| PACEMAKER OF THE HEART | SA NODE |
| SPECIALIZED CONDUCTION TISSUE IN THE INTERVENTRICULAR SEPTUM; DIVIDES INTO THE RIGHT AND LEFT BRANCHES | BUNDLE OF HIS |
| PLACE WHERE THE ELECTRICAL SIGNAL NORMALLY ARISES | SA NODE |
| THE ELECTRICAL SIGNAL SPREADS FROM THE CONDUCTION TISSUE IN THE ATRIA TO THIS STRUCTURE | AV NODE |
| AREA OUTSIDE THE SA NODE THAT GIVES RISE TO AN ELECTIRCAL SIGNAL | ECTOPIC FOCUS |
| THESE FAST-CONDUCTING FIBERS SPREAD THE ELECTRICAL SIGNAL THROUGHOUT THE VENTRICULAR WALL | PURKINJE FIBERS |
| RECORD OF THE ELECTRICAL ACTIVITY OF THE HEART (A HEART CHART) | ELECTORCADIOGRAM (ECG) |
| ELECTRICAL ACTIVITY APPEARS NORMAL AND THE SIGNAL ARISES WITHIN THE SA NODE | NORMAL SINUS RHYTHM (NSR) |
| LENGTHING OF THIS TIME INDICATE HEART BLOCK | P-R INTERVAL |
| ELECTRICAL EVENT THAT STIMULATES ATRIAL CONTRACTION | P WAVE |
| ELECTRICAL EVENT THAT STIMULATES VENTRICULAR MYOCARDIAL CONTRACTION | QRS COMPLEX |
| ECG RECORDING THAT REPRESENTS THE TIME IT TAKES FOR THE ELECTRICAL SIGNAL TO TRAVEL FROM THE SA NODE TO THE VENTRICLES | R-R INTERVAL |
| RELATED TO LOCATION OF THE _________. THORACIC CAVITY, MEDIASTINUM, AND PRECORDIUM. | THE HEART |
| OXYGENATED BLOOD IS FOUND IN WHICH STRUCTURE? | PULMONARY VEINS |
| WHAT IS THE CAUSE OF THE HEART SOUNDS "LUBB-DUBB"? | VIBRATIONS CAUSED BY CLOSURE OF VALVES |
