Which of the following condition we find systolic anterior motion of Mitral valve?
Systolic anterior motion (SAM) of the mitral valve is the cause of dynamic outflow obstruction in most patients with hypertrophic cardiomyopathy (HCM).
Echocardiographic features of hemodynamically significant effusions include -------------respiratory variation of tricuspid, aortic or mitral Doppler tracings.
Echocardiographic features of hemodynamically significant effusions include > 25% respiratory variation of tricuspid, aortic or mitral Doppler tracings.
Which of the following maneuver is used to treat upper airway obstructions by foreign objects?
To perform abdominal thrusts (Heimlich maneuver) on someone else:
1.Stand behind the person. Place one foot slightly in front of the other for balance.
2.Make a fist with one hand.
3.Grasp the fist with the other hand.
4.Perform between six and 10 abdominal thrusts until the blockage is dislodged.
When premature ventricular complexes [ PVCs] are more than ------%of all beats in 24 hours EKG monitoring it requires treatment.
Frequent PVCs(>10,000 PVCs/24 hours EKG monitoring or >10% of all beats) require treatment
Which of the following is Typical AVNRT ?
Typical AVNRT (also described as common AVNRT or slow-fast AVNRT):
The impulse travels over the slow pathway towards the ventricles and returns via the fast pathway to the atria.
The retrograde P wave (or Atrial echo) shows up at the end of the QRS.
90 % of all patients with AVNRT are diagnosed with typical AVNRT.
All of the following are TRUE about AVNRT EXCEPT -
Typical AVNRT- slow-fast AVNRT : 90 % of all patients with AVNRT are diagnosed with typical AVNRT. The distance between the R and P waves is less than 100ms
Which of the following is themost common cause of paroxysmal supraventricular tachycardia?
AVNRT is the most common cause of paroxysmal supraventricular tachycardia (PSVT).
AV tachyarrhythmias include the following:
AV nodal reentrant tachycardia (AVNRT)
AV reentrant tachycardia (AVRT)
Junctional ectopic tachycardia (JET)
Nonparoxysmal junctional tachycardia (NPJT)
All of the following form the boundaries of Koch's triangle EXCEPT?
Boundaries of Koch's triangle - coronary sinus orifice, tendon of Todaro, and septal leaflet of the right atrioventricular valve
What is the name of atrio-fascicular fibers entering the ventricular myocardium in the region of the right bundle branch?
In Wolff–Parkinson–White syndrome with "type A pre-excitation" the accessory fibers communicate between -
Bundle of Kent is an abnormal extra or accessory conduction pathway between the atria and ventricles
Pathway may communicate between the left atrium and the left ventricle, in which case it is termed a "type A pre-excitation", or between the right atrium and the right ventricle, in which case it is termed a "type B pre-excitation"
