NCCT ECG Practice Test Questions and Answers | Rated A+

the p wave should always be upright in leads 1 and 2 - what would be considered a cardinal feature of sinus rhythm? U - what is a small wave (similar to the P wave) that sometimes appears after the T wave, and is thought to represent late repolarization of the Purkinje fibers in the ventricles? sick sinus rhythm - a disturbance of SA nodal function that results in a markedly variable rhythm is known as atrial fibrillation - what term best describes a cardiac condition that demonstrates a sinus rate of 250 to 350 beats per minute T - which wave represents ventricle depolarization ventricular tachycardia - which of these ECG findings indicates a pulse greater than 100 beats per minute with at least three irregular beats in a row atrial depolarization - the p wave is indicative of premature atrial contraction with pvcs - what best describes this rhythm strip trigeminy pvcs - what best describes this rhythm strip sinus bradycardia - what best describes this rhythm strip isolated pvc - what best describes this rhythm strip diastole - occur when the ventricle relax, and the blood flows into the atrium from the vena cava and pulmonary exposure to interference - what is the LEAST likely to cause under-sensing in the ECG over-sensing - drug therapy, hyperkalemia, Twiddler's syndrome, and battery depletion can all be occasional causes of ECG ________. pericardium - the membranous sac filled with serious fluid that encloses the heart and the roots of the aorta and other large blood vessels is known as the atrial fibrillation - the abbreviation AF is most commonly used for fibrillation - is the rapid, irregular, and unsynchronized contraction of the muscle fibers of the heart hypoxia - is the medical term that means "a shortage, but not an absence, of oxygen in the body." it should be upright in the aVR - what is not a feature of a normal p wave left ventricle and aorta - Aortic Valve Stenosis (AVS) is the narrowing of the heart valve between the an electrocardiogram on an exercising patient - the most common cardiac stress test consists of? blood - the word element HEMA means embolism - the blocking of a blood vessel by a clot or other substance in the blood stream is called dyspnea - the medical term for painful or difficult breathing is bradycardia - a sinus rhythm with a resting heart rate of 40 bpm or less is known as in the mid-axillary horizontal to lead 4 - in hooking up the electrodes to the patient's chest V6 goes pain level - which of these is not considered part of the typical recording of vital signs
