MA 2 UNIT 2

EKG

QuestionAnswer
WHAT IS AN ELECTROCARDIOGRAM? RECORD OF THE ELECTRICITY IN YOUR HEART DURING
WHERE IS AN ELECTROCARDIOGRAM PLACED ON THE BODY? THE SURFACE
WHEN IS THE ELECTRICITY GENERATED BY THE HEART? DURING CONTRACTION & RELAXAION
WHAT ARE THE ABBREVIATIONS FOR ELECTROCARDIOGRAM? EKGECG
WHAT 4 THINGS ARE RECORDED BY THE EKG? THE AMOUNT OF ELECTRICAL ACTIVITYTHE TIME REQUIRED TO TRAVEL THROUGH THE HEART DURING EACH COMLETE HEARTBEATTHE RATE OF THE HEARTBEATTHE RHYTHM OF THE HEARTBEAT
WHEN IS AN EKG PART OF A PHYSICAL? PEOPLE 40+
IF YOU ARE 40+ WHEN IS A GOOD TIME TO GET AN EKG? BEFORE BEGINNING ANY SERIOUS EXERCISE PROGRAM
WHAT IS A CARDIAC CYCLE? ONE COMPLETE HEARTBEAT
WHERE DOES THE CARDIAC CYCLE BEGIN? IN THE S-A node
WHAT ARE SOME OTHER NAMES FOR THE S-A NODE? SINOATRIAL NODESPARKPACEMAKER
WHERE IS THE S-A NODE LOCATED? TOP OF RIGHT ATRIA
WHAT HAPPENS IN THE S-A NODE? AN ELECTRICAL IMPULSE IS SENT OUT TO YOUR HEART
WHAT HAPPENS WHEN THIS IMPULSE IS SENT OUT? CAUSES THE ATRIA TO CONTRACT & SQUEEZE BLOOD INTO THE VENTRICLES
WHERE DOES THE IMPULSE GO NEXT? A-V node
WHAT IS ANOTHER NAME FOR THE A-V NODE? ATRIOVENTRICULAR NODE
WHAT IS THE A-V NODE MADE OF? A MASS OF MODIFIED HEART MUSCLE
WHERE IS THE A-V NODE LOCATED? THE BASE OF THE RIGHT ATRIUM
WHERE DOES THE IMPULSE GO NEXT? THE bundle of His
WHERE IS THE BUNDLE OF His LOCATED? IN THE SEPTUM
WHERE DOES THE IMPULSE GO NEXT? BUNDLE BRANCHES
WHERE DO THE BUNDLE BRANCHES GO? LEFT & RIGHT OF THE SEPTUM
WHERE DOES THE IMPULSE GO NEXT? PURKINJE FIBERS
WHAT DO THE PURKINJE FIBERS LOOK LIKE? BRANCHES ALL OVER THE VENTRICLES
WHY ARE THE PURKINJE FIBERS SPREAD ACROSS THE VENTRICLES? TO MAKE THEM CONTRACT
WHEN DOES DEPOLARIZATION OCCUR? WHEN THE VENTRICLES CONTRACT
WHEN DOES REPOLARIZATION OCCUR? WHEN THE HEART RETURNS TO ITS NORMAL STAGE
WHEN DOES THE HEART REST? AFTER REPOLARIZATION
WHEN DOES AN ARRHYTHMIA OCCUR? WHEN THERE IS ANY ELECTRICAL DISTURBANCE IN THE PROCESS OF THE CARDIAC CYCLE
WHAT DOES THE EKG MACHINE PICK UP ON? THE ELECTRICAL IMPULSE OF THE HEART
WHAT DOES THE NORMAL EKG CYCLE CONSIST OF? WAVES THAT HAVE BEEN LABELED P, QRS, & T
WHAT ARE P WAVES? CONTRACTION OR DEPOLARIZATION OF THE ATRIA
WHAT IS A QRS COMPLEX? CONTRACTION OR DEPOLARIZATION OF THE VENTRICLES
WHAT IS A T WAVE? RELAXATION OR REPOLARIZATION OF THE VENTRICLES
WHAT IS A U WAVE? THE PATIENT HAS LOW LEVELS OF POTASSIUM
WHEN DOES THE U WAVE APPEAR AFTER THE T WAVE
HOW BIG IS A U WAVE? SMALLER THAN THE T WAVE
WHAT IS A BASE LINE? A FLAT HORIZONTAL LINE THAT RUNS THE LENGTH OF THE EKG & SEPERATES WAVES
WHAT ARE SOME OTHER NAMES FOR THE BASE LINE? FLAT LINEISOELECTRIC LINE
ON THE HORIZONTAL LINE OF THE EKG PAPER, ONE SMALL REPRESENTS WHAT? 0.04 SECONDS
ON THE VERTICAL LINE, WHAT DOES ONE SMALL BLOCK REPRESENT? 1MM OF CARDIAC VOLTAGE
ARE THESE MEASUREMENTS ACCEPTED WORLD WIDE? YES
WHAT IS THE NAME OF THE INSTRUMENT THAT MAKES THE LINES ON THE EKG PAPER? HEATED STYLUS
WHAT MAKES THE STYLUS MOVE? THE VOLTAGE OF THE HEART
IS THERE INK IN THE STYLUS? NO
HOW DO THE MARKS APPEAR ON THE EKG PAPER? THE STYLUS HEATS THE PAPER & MELTS THE PLASTIC COVERING IT WHEN IT MOVES
SHOULD YOU PLACE AN EKG READING IN THE SUN? NO
WHAT WOULD HAPPEN IF YOU PLACED AN EKG READING IN THE SUN? TURN BLACK
WHO NEEDS TO UNDERSTAND ARTIFACTS? THE MA
WHAT ARE THE 3 MOST COMMON ARTIFACTS? SOMATIC TREMOR, WANDERING BASELINE, AC INTERFERENCE
WHAT CAUSES A SOMATIC TREMOR? THE PATIENT MOVING, TALKING, COUGHING, BEING TENSE, OR THEY MAY HAVE A NERVOUS DISORDER
WHAT CAUSES A WANDERING BASELINE? ELECTRODES BEING TOO LOOSE, TOO TIGHT, NOT ENOUGH OR TOO MUCH GEL, CORRODED OR DIRTY ELECTRODES
WHAT CAUSES AC INTERFERENCE? PATIENT HAS CELL PHONE IN POCKETOTHER ELECTRICITY BEING RAN TOO CLOSE TO THE EKGIMPROPER GROUNDING OF THE EKGLEAD WIRES CROSSED & NOT FOLLOWING BODYCORRODED OR DIRTY WIRES
WHAT ARE ELECTRODES? SMALL METAL PLATES THAT PICK UP ELECTRICAL ACTIVITY OF THE HEART
WHERE ARE THE ELECTRODES PLACED? ON THE SURFACE OF THE BODY
HOW MANY ELECTRODES DOES THE STANDARD 12 LEAD EKG HAVE? 5 OR 10
WHERE ARE THE 2 UPPER ELECTRODES PLACED ON THE BODY? EACH ARM
WHERE ARE THE 2 LOWER ELECTRODES PLACED? EACH LEG
WHERE ARE THE REMAINING 6 ELECTRODES PLACED? VARIOUS PLACES ON THE CHEST
