Wk 4 Terry Reynolds *ECG

Question 1

!!!

395. Possible echocardiographic findings in patients with Wolff-Parkinson-White type A syndrome include a(n):

A. Brief anterior displacement of the left ventricular wall.
B. Brief posterior displacement of the right ventricular wall.
C. Increase in the interval between mitral valve closure and pulmonic valve
opening.
D. Sharp, brief, downward posterior dip of the interventricular septum.

Answer 1

A: Brief anterior displacement of the left ventricular wall

*Note:

a relatively common heart condition that causes the heart to beat abnormally fast for periods of time. The cause is an extra electrical connection in the heart. This problem with the heart is present at birth (congenital), although symptoms may not develop until later in life.

Question 2

394. Possible echocadiographic findings in patients with Wolff-Parkinson-White type B syndrome include a(n):

A. Brief anterior displacement of the left ventricular wall.
B. Brief posterior displacement of the right ventricular wall.
C. increase in the interval between mitral valve closure and pulmonic valve
opening.
D. Sharp, brief, systolic downward posterior dip of the interventricular septum.

Answer 2

D: Sharp, brief, systolic downward posterior dip of the interventricular septum.

Question 3

!!!

393. Possible echocardiographic findings for patients with right bundle branch block include:

A. Decreased interval between tricuspid valve closure and pulmonic valve opening.
B. Early, systolic beaking of the interventricular septum.
C. Increased interval between mitral and tricuspid valve closure.
D. Systolic paradoxical septal motion.

Answer 3

C: Increased interval between mitral and tricuspid valve closure.

*Note: Right bundle branch block is a problem with your right bundle branch that keeps your heart’s electrical signal from moving at the same time as the left bundle branch.

Instead of moving together on the left and right sides, the signal on the right side is running behind. This creates an irregular heartbeat. Usually, the problem isn’t serious.

Question 4

!!!

392. Electrical pacing of the right ventricle mimics the electrocardiographic and echocardiographic findings of:

A. Complete atrioventricular block.
B. Left bundle branch block.
C. Right bundle branch block.
D. Wolff-Parkinson-White syndrome.

Answer 4

B: Left bundle branch block.

Question 5

391. The principal echocardiographic feature of the left bundle branch block is:

A. Early systolic dip.
B. Hyerkinesis of the interventricular septum.
C. Hyperkinesis of the posterior wall of the left ventricle.
D. Posterior motion of the interventricular septum.

Answer 5

A: Early systolic dip

*Note: LBBB, the bundle branch that carries the electrical impulse to your left ventricle is either partially or completely blocked. This problem causes your right ventricle to contract before your left ventricle, making it harder for your heart to pump blood efficiently.

Question 6

Low voltage of the QRS complex throughout the electrocardiogram is often found in:

A. Constrictive pericarditis
B. Mitral stenosis
C. Pericardial effusion
D. Pleural effusion

Answer 6

C. Pericardial effusion
