EKG Test
MA JATC
| Question | Answer |
|---|---|
| Which test is used to help diagnose cardiac disease conditions? | ECG |
| Which of the following will NOT help create a good ECG tracing? | Tell the patient to take big, deep breaths |
| Where do the electrical impulses of the heart begin? | sinoatrial (SA) node |
| Ventricular depolarization correlates with which part of the ECG reading? | QRS complex |
| Ventricular systole means . . . | Ventricles are contracting |
| An ECG is . . . | electrocardiogram |
| The medical term for 'flatline' is | asystole |
| How many electrodes are placed for a 12 lead EKG? | 10 |
| A diagnostic test that requires the patient to exercise while the heart is being monitored is | stress test |
| A small portable device that continually monitors EKG rhythms is | Holter monitor |
| Electrodes on the arms and legs should be placed | at approximately the same level |
| 1. | SA node |
| 2. | AV node |
| 3. | Bundle of His |
| 4. | right bundle branch |
| 5. | left bundle branch |
| 6. | Purkinje Fibers |
| Artifact flashcards | wandering baseline |
| Normal | Normal Sinus Rhythm |
| black fast lines at the end | somatic tremor |
| What is the name for any interference on the ECG? | artifact |
| small waves | v-fib |
| close to flat | asystole |
| small separated | sinus bradycardia |
| wave but p doesn't exist or its really fast/black | alternating current interference |
| Which of the following is most likely to be the cause of somatic tremor artifact? | Patient movement |
| 1- | Right atrium |
| 2- | Tricuspid valve |
| 3- | Right ventricle |
| 4- | pulmonary valve |
| 5- | pulmonary arteries |
| 6- | pulmonary vein |
| 7- | left atrium |
| 8- | bicuspid valve |
| 9- | left ventricle |
| 10- | aortic valve |
| 11- | aorta |
| The surge of electricity at the QRS complex is due to... | ventricular depolarization |
| The T wave on an EKG is caused by... | ventricular repolarization |
| Why is V-tach a deadly rhythm? | Because the ventricles are not able to fill adequately with blood |
| Which part of the electrical conduction of the heart is directly responsible for ventricular contraction? | Perkinje Fibers |
| The _______ is the pacemaker of the heart | SA node |
| and the _______ is the backup pacemaker of the heart. | AV node |
| How long are holter monitors worn? | 24-48 hours |
