CARDIAC POSITION

100

THE RT VENTRICLE LIES __________ TO THE LEFT VENTRICLE?

ANTERIOR

200

DEXTROCARDIA IS?

THE HEART IS POINTED TOWARD THE RIGHT SIDE OF THE CHEST INSTEAD OF NORMALLY POINTING LEFT.

300

DEXTROPOSITION IS? WHICH WAY DOES THE APEX POINT?

THE HEART IS LOCATED IN THE RIGHT SIDE OF THE CHEST WITH THE APEX POINTING LEFT.

400

EXTREME LEVOCARDIA IS?
(WHICH SIDE)

WHEN THE HEART IS LOCATED VERY LATERAL ON THE LEFT SIDE OF THE CHEST.

500

MESOCARDIA IS? WHICH DIRECTION IS THE APEX?

THE HEART IS LOCATED IN THE MIDDLE OF THE CHEST WITH THE APEX POINTING MIDLINE.

VALVES

100

MITRAL VALVE-HOW MANY LEAFLETS AND NAME THEM

2 LEAFLETS
ANTERIOR AND POSTERIOR

(FUN FACT: THE ANTERIOR IS NORMALLY LARGER THAN THE POSTERIOR)

200

AORTIC VALVE- HOW MANY LEAFLETS/CUSPS AND WHAT ARE THE NAMES 

3 LEAFLETS/CUSPS
RIGHT CORONARY, LEFT CORONARY, AND NON-CORONARY

300

PULMONARY VALVE- HOW MANY LEAFLETS AND WHAT ARE THE NAMES

3 LEAFLETS
RIGHT, LEFT, AND ANTERIOR

400

WHICH VALVE IS MOST ANTERIOR? 

PULMONARY VALVE

500

TRICUSPID VALVE- HOW MANY LEAFLETS AND THE NAMES 

3 LEAFLETS
ANTERIOR, POSTERIOR, AND SEPTAL/MEDIAL

CORONARY CIRCULATION

100

TRUE OR FALSE: INCREASED LEFT VENTRICULAR DIASTOLIC PRESSURES WILL DECREASE CORONARY ARTERY FLOW?

TRUE: THE MAJORITY OF THE ANTEROGRADE FLOW IN THE CORONARY OCCURS IN EARLY VENTRICULAR DIASTOLE. DUE TO THE INCREASED DIASTOLIC PRESSURE, IT WILL HAVE A SHORTER VENTRICULAR DIASTOLE (IN MOST CASES).

200

RCA- NAME 3/4 SEGMENTS THAT THIS CORONARY ARTERY SUPPLIES

BOTH ATRIA
THE ATRIAL SEPTUM
THE RIGHT VENTRICULAR FREE WALL
THE RIGHT VENTRICULAR APEX

300

80% OF THE POSTERIOR DESCENDING ARTERIES (PDA) ORIGINATES FROM?

80% OF PDAS ORIGINATE FROM RCA

20% OF PDAS ORIGINATE FROM LCA. THE PDA SUPPLIES THE INFERIOR VENTRICULAR SEPTUM AND INFERIOR WALL OF THE LEFT VENTRICLE.

400

THE LEFT MAIN CORONARY ARTERY (LCA) ORIGINATES FROM?

AORTIC ROOT AT THE LEFT CUSP OF THE AORTIC VALVE 

500

WITHIN THE CORONARY CIRCULATION WHICH ANATOMICAL FEATURE HAS THE LOWEST 02 SATUARTAION?

CORONARY SINUS

THIS DRAINS THE VENOUS BLOOD FROM THE CARDIAC MUSCLE INTO THE RIGHT ATRIUM. IF RIGHT ATRIAL PRESSURE INCREASES THE CORONARY SINUS WILL DILATE.

ANATOMY/RANDOM

100

NAME THE 3 BRANCHES THAT COME OFF OF THE AORTIC ARCH

INNOMINATE (AKA BRACHIOPHALIC)
LEFT COMMON CAROTID
LEFT SUBCLAVIN

200

ALL OF THE FOLLOWING CAUSE AN INCREASED HEART RATE, EXCEPT:
A: EXERCISE
B: HYPERKALEMIA
C: EPINEPHRINE
D: HYPERCALCEMIA 

B: HYPERKALEMIA 

300

WHICH TWO VEINS FORM THE IVC?

LEFT AND RIGHT ILIAC VEINS

400

DEFINE THE ELECTRICAL DELAY PERIOD IN THE CONDUCTION SYSTEM.

BRIEF PERIOD WHEN THE ELECTRICAL ACTIVATION OF THE VENTRICLE OCCURS, BUT THE MECHANICAL CONTRACTION HAS NOT YET STARTED. (APPROXIMATELY 35MS)

500

NAME THE 4 PULMONARY VEINS 

RIGHT UPPER
RIGHT LOWER
LEFT UPPER
LEFT LOWER

CARDIAC CYCLE

100

On an EKG, WHEN DOES IVRT OCCUR?

OCCURS AFTER THE T-WAVE 

200

ON EKG, WHEN DOES IVCT OCCUR?

OCCURS AFTER THE R-WAVE

300

NAME THE 4 PHASES OF VENTRICULAR DIASTOLE

1-ISOVOLUMIC RELAXATION PERIOD
2-RAPID FILLING PERIOD
3-DIASTASIS
4-ATRIAL CONTRACTION

400

NAME THE 3 PHASES OF VENTRICULAR SYSTOLE?

1-ISOVOLUMIC CONTRACTION PERIOD
2-RAPID EJECTION PHASE
3-REDUCED EJECTION PHASE

500

HOW MUCH BLOOD IS EJECTED FROM THE ATRIA DURING THE EARLY RAPID FILLING PHASE

70% IN THE EARLY RAPID FILLING PHASE AND 30% DURING THE ATRIAL CONTRACTION
