Double-density sign in right border of heart is seen in which of following condition?
Double-density sign - also called - double right heart border,
-seen on frontal chest radiographs in the presence of left atrial enlargement,
-occurs when the right side of the left atrium extends behind the right cardiac shadow,
In which of following condition "atrialization" of a portion of the morphologic right ventricle is found?
The portion of the right ventricle proximal to the functional tricuspid valve becomes “atrialized.”
-The anterior leaflet of the tricuspid valve is large and redundant
'Himalayan' P waves in ECG seen in -
The Himalayan P waves are a result of a massively dilatated right atrium.
-Classical for - Ebstein anomaly,
-Can be seen in -few other conditions such as tricuspid atresia and combinedtricuspid and pulmonary stenosis
What % of individuals with Ebstein's anomaly have an accessory pathway with evidence of Wolff-Parkinson-White syndrome?
About 50% of individuals with Ebstein's anomaly have an accessory pathway with evidence of Wolff-Parkinson-White syndrome,
Which of the following place in heart Mahaim pathways are typically seen?
Mahaim pathways are typically seen on the right side of the heart, with their ventricular connection lying within or close to the right bundle branch
Fibres often conduct slowly and in one direction only - from the atria to the ventricles (antegrade conduction); not from the ventricles to the atria (retrograde conduction).
Which of the following drug is associated with increased risk of Ebstein's anomaly?
Maternal use of lithium during the first trimester - associated with an increased risk of cardiac malformations, including Ebstein's anomaly
Walking man sign is seen in?
Mitral valve stenosis
Walking man sign is seen on a lateral chest radiograph
-
-It is a sign of left atrial enlargement.
-Posterior displacement of the left main bronchus such that it no longer overlaps the right bronchus.
-The left and right bronchus on a lateral chest radiograph seen as inverted 'V', that looks like the legs of a walking man.
Malar flush is seen in which of the following ?
'Mitral facies' - Low cardiac output in severe mitral stenosis - which causes cutaneous vasoconstriction,
-
Rosy cheek -Localized vasodilation
Rest of the face has a bluish tinge due to cyanosis -Low cardiac output
-
Localized vasodilation due to CO2 retention - can cause malar flush
-
Which of the following shows central enlargement of the pulmonary arteries with peripheral "pruning"?
Pulmonary Hypertension
- Chest x-ray typically shows central enlargement of the pulmonary arteries with peripheral "pruning."
What is the normal mean QRS vector?
Mean QRS vector-
■ normal between −30° and +90°
■ left axis deviation between −30° and −90°
■ right axis deviation between +90° and +150°.
