patient displays an ECG abnormality consistent with atrial enlargement. Which ECG wave/interval do you anticipate shows an abnormal morphology on the ECG? Group of answer choices P-wave QRS complex

Kayla Christianson, CMA, has been employed six years by the cardiology practice of three physicians. She is a graduate of a CAAHEP-accredited school. Furthermore, Kayla received extensive hands-on training performing ECGs while doing her required externship.Kayla has completed an ECG ordered by Dr. Hsu for Mrs. Warner, a 76-year-old patient. Dr. Hsu, Kayla’s boss, telephoned her explaining that he was behind schedule doing rounds at the hospital. He asked her to do him a favor and interpret Mrs. Warner’s ECG, sign his name, and fax the report to Mrs. Warner’s referring internist, who is expecting the results. Given the scope of Kayla’s education, training, and years of experience as a CMA, would this “favor” fall within the AAMA guidelines of her responsibilities? Would any portion of Dr. Hsu’s request fall within the guidelines? If so, which portion(s)? Is an exception to these guidelines ever allowed? How should Kayla respond to Dr. Hsu?

In the ECG pictured, which part of the P-QRS-T pattern indicates where ventricular contraction is occuring?

What is happening during the phase labeled with the arrow? Atrial depolarization Ventricular depolarization Ventricular repolarization or  AV valve closure

You are presented with a stack of ECGs on your fist day of your cardiology rotation and are given a single instruction: “read them”. As you progress through the pile, you note the following abnormalities. Explain form where in the heart of the cardiac conduction system each abnormality might have come: Absent P waves Abnormally long QRS complex Abnormally long P-R interval Extra QRS complex

Trace the journey of a drop of blood starting from the right atrium, continuing to the right thumb, and returning to the right atrium.  This would include a trip through the heart. Be sure to identify both the arterial and venous vessels as well as all of the relevant structures within the heart. Considering the online nature of this exam, drawings are not required. Simply type in the order of structures with a dash (-) between structures.

in an ECG recording, the RR interval is 500 msecs. what is the heart rate?

If you have a resting heart rate of 125 beats/min or bpm then you have: a normal heart rate, bradycardia, or tachycardia

I don’t understand this page in my lab book
