AAH PRACTICE TEST QUESTIONS WITH CORRECT ANSWERS GRADED TO PASS

The T Wave represents - ventricular re-polarization If the heart is in a state of asystole - There is no contraction What are the bipolar leads - I, II, and III The most common type of supraventricular Tachycardia is - AV nodal Reentrant tachycardia (AVNRT) In 2:1 AV block, the PR interval - Lengthens In sinus arrhythmia, a gradual decreasing of the heart rate is usually associated with: - Expiration When the cardiac muscle cell is stimulated, the cell is said to: - Depolarize Leads, II,III AVF view which portion of the heart - Inferior A regular rhythm with a rate of 100-250 beats per minute would most likely be - Atrial Tachycardia Artifact can be cause by - Alternating currents, Patient movements, poorly applied or dirty sensors When you have more than one premature beat that are of a different kind they are called - Multifocal What is the rate range for junctional tachycardia? - 100-180 Another name for the S-A node is - Pacemaker Wolff-Parkinson-White Syndrome is associated with - Short P-R interval, delta wave, wide QRS complex How are frequent PAC's usually managed? - Correcting the underlying cause The term for three or more PVC's occurring in a row at a rate of more than 100 beats per min is? - A run of ventricular Tachycardia How do you determine whether the atrial rhythm on an ECG tracing is regular or Irregular ? - Compare to P to P Intervals Tall, Peaked T waves observed on the ECG are most commonly seen in patients with. - Hyperkalemia Leads V3 and V4 view which portion of the heart? - Anterior A normal rhythm with a normal rate is a - Normal Sinus Rhythm Defibrillation is a - Shock to the heart to stop the heart and shock to the heart to change rhythms Which of the following small waves sometimes appears between the T wave and P wave? - U wave What structure maintains the control of the control of blood flowing through the heart? - Valves Sinus rhythm at a rate of 48 would be considered - Bradycardia The function of the AV node is to - Delay the electrical signal to the Purkinje Fibers The inherent rate for the AV Junction is - 40-60 bpm The term for three or more PVC's occurring in a row at a rate of more than 100 beats - A run of ventricular tachycardia The usual rate of nonparoxymal junction tachycardia is - 101-140 bpm When the cardiac muscle cell is simulated , the cell is said to - Depolarize Leads V1 and V2 view which portion of the heart? - Septal In atrial Tachycardia, the atrial rate can be as low as - 100-150 A QRS measurement of less than ________ seconds indicates a supraventricular - 0.12 A straight line on the ECG strip produced by the stylus when the EKG isn't connected to a patient is called - Isoelectric line The atrial rate in atrial fibrillation is - More than 350 bpm Normally a complete ECG consists of __________ leads - 12 The anterior surface of the heart consists primarily of the : - Right ventricle The ________ supplies the right atrium and ventricle with blood - Right coronary Artery The inherent rate of the AV Junction is - 40-60 bpm The segment representing the time fro the end of the P wave to the onset of the QRS complex is the - P-R segment Impulses from the AV node go through the ____________ tot the right an left branches - Bundle of His The single most important thing you can do to prevent the spread of infection is - Wash your hands When the atria and ventricles are seen to be beating independently is called - Third- degree heart block Wenckebach is characterized by increasingly PRI's followed _________a P wave - Blocked
