NURG 533 Patho Module 6: Cardiovascular
1. What part of the ECG represents Atrial depolarization?: P wave
2. What part of the ECG represents the time from onset of atrial activation to the onset of ventricular
activation?: The PR interval
3. What part of the ECG represents the sum of all ventricular depolarizations?-
: The QRS complex
4. What part of the ECG represents ventricular myocardium depolarized?: ST interval
5. What part of the ECG represents electrical systole of the ventricles?: QT interval
6. The time it takes for the entire depolarization and repolarization of ventri- cles.: Q-wave-end of T-wave
7. How long is a normal PR interval?: 0.12-0.20 seconds
8. How long is a normal QRS complex?: 0.06-0.10 seconds
9. how long is a normal Q-T interval?: 0.4seconds
10.How does the QT interval relate to heart rate?: It varies inversely with heart rate. It will increase with a decrease
in heart rate and will decrease with an increase in heart rate.
11.What is the drug of choice to decrease lipids?: statins
12.Lipids are a modifiable risk factor for what?: Coronary Artery Disease
13.Also known as mucocutaneous lymph node syndrome.: Kawasaki disease
14.This is an acute self-limiting systemic vasculitis that may result in cardiac sequelae. Inflammation of blood
vessels. Approximately 80% of cases occur in children under 5. The cause is unknown.: Kawasaki disease.
15.What are the three periods/phases of Kawasaki disease?: The Acute, Sub- acute, and Convalescent
16.This phases consists of fever of 102 that does not go away with Tylenol, it can get as high as 104 and lasts at
least 5 days and up to 2 weeks. Conjunc- tivitis without drainage, bright red, chapped lips, red mucous
membranes with a white coating on strawberry tongue, lymphadenopathy, visible red bumps on back of tongue,
red palms and soles, swelling of hands and feet, rash on middle of body that is not blistered, peeling skin of hands,
feet, and genitals, joint pain, and swelling on both sides of body. Myocarditis can occur: Acute phase
17.During this phase, patient is most at risk for cardiac sequela which in- cludes development of aneurysms in
coronary arteries. Begins with fever ends and continues until clinical signs resolve. Desquamation of palms and
