Tachyarrhythmias

Question 1

Difference between sinus tachy and atrial tachy

Answer 1

Sinus: gradual increase in rate
Atrial: abrupt increase in HR

Question 2

Drug blocking the If current causing sinus node depolarization

Answer 2

Question 3

Tachycardiafrom the normal sinus node area that occurs without an identifiable precipitating factor

Answer 3

Inappropriate sinus tachycardia

Question 4

MACROreentrant atrial tachycardia

Answer 4

Atrial Flutter

Question 11

MC preexcited tachycardia

Answer 11

Antidromic AV reentry

Question 12

Management for hemodynamically stable, REGULAR, NARROW QRS tachycardia

Answer 12

Vagal maneuvers
IV adenosine
IV verapamil/diltiazem

Question 13

Management of irregular, WIDE COMPLEX tachycardia

Answer 13

Cardioversion

Question 14

Large reentry circuit often associated with areas of scar in the atria

Question 16

Mansgement for new onset AF and hemodynamically unstable

Answer 16

Synchronized cardioversion

Question 17

Approach of anticoagulation in AF

Answer 17

Anticoagulate continuously for 3 weeks before and minimum of 4 weeks after cardioversion
