If your patients cardiac rhythm is life-threatening your first action should be too - ANSWERS-Check the patient Using a memory method for calculating overall heart rate which sequence is correct - ANSWERS- 300 - 150 - 100 - 75 - 60 - 50 - 43 - 37 The learner is caring for a patient with sinus bradycardia the patient's blood pressure is running low due to decreased cardiac output. What does sinus bradycardia cause a drop in cardiac output? - ANSWERS- Blood is pumping too slowly to supply blood with enough blood The type of regularity in which acute RS complex very widely throughout the rhythm is - ANSWERS-Accelerated idioventricular rhythm A bundle branch block is characterized by - ANSWERS-You are as complex widened and downwardly deflected Is right bundle branch block, which chamber invasion is slowed - ANSWERS-Right ventricle When someone sinus impulses get through the ventricles and some do not result in drop beats, it is considered to be what type of AV block - ANSWERS-Second-degree mobitz one
When there is no cardiac electrical activity, it is called - ANSWERS- Asystole When there is a delay in transmission of the sinus impulses to the ventricle resulting in prolonged interval - ANSWERS-1st degree block The junctional rhythm with the heart rate of 125 the PA is introverted and proceeds a QRS complex. The PR interval is less than 0.12 and the QRS interval is 0.10 seconds is called. - ANSWERS-National tachycardia Wandering our pacemaker has at least three different shapes - ANSWERS-Different shaped P waves Sup ventricle tachycardia originates - ANSWERS-At or above the AV node Following a is PVC usually what - ANSWERS-A fully compensatory pause Multifocal PVS are those that - ANSWERS-Multiple QRS morphologies no P wave Atrial flutter has an atrial rate of - ANSWERS- 250 - 350
The P waves represent? - ANSWERS-depolarization of the atria The QRS represent - ANSWERS-Depolarization of ventricles What is QT interval in this strip - ANSWERS-Measure from beginning of QRS complex to the end of the T wave Lead one shows the difference in electrical voltage between and the AVR Lead as positive pole on - ANSWERS- Right arm and left legs Joining lead I , II and III at their ends produce - ANSWERS- Einthoven's triangle The V1 electrode is located at while the AVL has a positive pull at the - ANSWERS-V1- 4th intercostal space AVL - left Arm Which is the indication for immediately termination of a stress test - ANSWERS-A drop in systolic pressure, dizziness, sweating Holter monitor is - ANSWERS-A type of ambulatory ECG device that is portable, cardiac monitor
Junctional rhythm originate in the - ANSWERS-AV node or bundle of his pericardium fluid - ANSWERS-Reduce friction The T wave represent - ANSWERS-Repolarization of the ventricle myocardium What are the rules in measurement for normal QRX complex - ANSWERS-0.06 to 0.12 seconds Irregular rhythm is one in which the R to R interval are what - ANSWERS-Regular Correct calibrator on the ECG machine is evidence by the calibration wave that is - ANSWERS-10mm/mv The ECG is a recording of the patient - ANSWERS-How the heart is functioning The ST segment is located between - ANSWERS-End of S wave and beginning of the T wave The normal ST segment is - ANSWERS-isoelectric , flat on the baseline
On your patience 12 lead ECG lead one wave and complexes are completely negative. AVR wave S are completely positive. What is most likely caused this? - ANSWERS-The right arm and left arm leaves are reversed Which is not a step in 12 lead ECG interpretation - ANSWERS- Determine if rhythm is regular or irregular,rate, analyze P waves, measure PR interval, measure QRS interval If the QRS and lead one, and AVL are both positive, the axis is - ANSWERS-Between - 30 + Your patient has chills what kind of artifact can produce this - ANSWERS-Muscle tremor is a type of motion artifact If a pacemaker fails to fire what is shown on the ECG - ANSWERS- Pacing spikes are absent 60 cycle interference is commonly caused by - ANSWERS-External source, lights, motors, alternating current cables
