| Echocardiography is used in the diagnosis of incompetent cardiac valves (t,f) | True |
| Chronic hypertension may result in left ventricular | Hypertrophy |
| Patients with primary (BLANK)maybe a symptomatic until serious health problems occur | Hypertension |
| (BLANK) causes pulmonary edema, dyspnea, orthopnea, and tachycardia | Left sided heart failure |
| Patients with (BLANK)must pay particular attention to a sudden gain in weight | Congestive heart failure |
| A BLANK)maybe a life threatening problem because of the potential for embolus formation | DVT |
| Tachycardia is defined as | A heart rate faster than normal |
| Bradycardia is defined as | A heart rate slower than normal |
| If the ECG recording appears as a series of interruptions on the baseline the medical assistant should | Check the cable connections to the electrodes |
| In which direction should lead connectors on electrodes be pointed when attached to the patient in preparation for the ECG | Towards the center of the body |
| On an ECG recording five millimeter boxes are seen between to r waves, what is the patient’s heart rate per minute | 60 bpm |
| If the ECG recording appears as a series of small uniform spikes in the baseline the medical assistant should do | Check for nearby electrical appliances |
| If the ECG recording appears with the baseline rising and falling the medical assistant should | Ask the patient to remain as still as possible, help the patient to relax and stay warm |
| If the ECG recording appears as a series of irregular jagged peaks the medical assistant should | Help patient to relax and stay warm |
| A monitor that a patient wears for 24 hours is called | Holter monitor |
| In a standard 12 lead ECG the measurement of current that the heart muscle produces between the right arm electrode and the left arm electrode is known as | Lead 1 |
| The greatest deflection from the baseline on the ECG is the | QRS complex |
| Which deflection from the baseline represents the repolarization of the ventricle | T wave |
| What part of the ECG complex represents the atrial depolarization | P wave |
| (BLANK)is the relaxation phase of the heart | Diastole |
| The (BLANK)controls the rate of heart contraction by initiating contractions 60 to 100 times per minute | SA node |
| The precordial leads which include AvR and AvL record the electric activity between specific points on the chest wall and within the heart (t,f) | False |

| Patients should hold their breath during the brief seconds necessary to record and ECG (t,f) | False |
| Documentation for an ECG should include whether the patient smoked a cigarette within 15 minutes of the procedure (t,f) | True |
| Digtoxicity may cause specific ECG changes (t,f) | True |
| One of the most specific ECG changes that occurs in patients with an MI is elevated T waves (t,f) | False |
| The P wave occurs during the contraction of (BLANK) and shows the beginning part of depolarization | Atrial |
| The QRS complex shows the contraction of both | Ventricles contracting and also reflects the completion of depolarization |
| The T wave indicates ventricular recovery or | Repolarization of the ventricle |
