Question
A patient is described by one of the hospital health care providers as having slower than normal conduction through the heart’s AV node. What is the effect of slower than normal conduction through the AV node on the electrocardiogram (EKG)? That is, if the cardiac impulse goes through the AV node, but it is conducted through the AV node slower than normal, what would the EKG look like compared to a normal EKG?
A. P wave is longer than normal
B. P wave is shorter than normal
C. QRS complex is shorter than normal
D. T wave is missing
E. PR segment is longer than normal
You correctly state that mitral stenosis ______ a cause of pulmonary edema.
a. can be
b. is not
As an excellent health provider, you know the correct answer to the following- that left sided heart failure causes ___________ edema because blood backs up behind the failing left side of the heart in the ________________.
A. pulmonary, lungs (or pulmonary circulation)
B. systemic, systemic circulation
Explanation / Answer
-mitral stenosis can be a cause of pulm0nary edema because in mitral stenosis the valve cannot open enough, as a reult less blood flow to the body by this pressure builds up and the upper heart chamber swells and this may results in blood and fluid collect in the lungs tissues. The left sided heart failure causes PULMONARY edema because blood blocks up behind the failing left side of the heart in the SYSTEMIC CIRCULATION.
A).P wave is longer than normal shows right atrial enlargement. B) P wave is shorter than normal shows left atrial enlargement. C)QRS complex is shorter than normal shows ventricles are depolarized. D)T wave missing shows coronary ischemia. E)PR segment is longer than normal shows delayed conduction of the sinoatrial nodal impulse to the ventricles
