Exam 1 Wrong Qs Flashcards
True or False, the sympathetic nervous system barely affects ventricular foci?
True
Supraventricular tachycardia is what? What are some examples? What would you see in an EKG?
Tachycardia originating above the ventricles (supra). Includes Afib and Aflutter. You’d see normal QRS cycles but P waves would vary
What is vaso vagal syncope?
A response of the parasympathetic overstimulation in which the person passes out
Wolf Parkinson White syndrome
Bundle of Kent allows electrical signal to bypass normal pathway, resulting in delta wave
What ion propagates the AV node and SA node?
Calcium
What ion propagates Atria, Ventricle, bundle of His and purkinje?
Na+
Electrical signal pathway?
SA node > AV node > Bundle of His > left and right bundle branches > purkinje fibers
Leads II, III, and AVF are the ___ leads
Inferior
Leads I and AVL are the ___ leads
Lateral
PAC vs PJC?
Early P wave embedded on the T wave (high amplitude). If amplitude is not high then we know the P wave is not embedded in which case it is missing, making it a PJC
Torsades vs V fib?
Torsades will have high amplitude and up and down amplitude
V fib will have normal or low amplitude but no identifiable QRS
A flutter is known as ________ pattern
Sawtooth
Ventricular tachycardia vs supra v tachycardia?
Vtach is a fast beat originating from the ventricles so abnormal QRS, whereas supra v tach originates above the ventricles so normal QRS but P prime
