EKG Flashcards
What is this and what can it cause?
Early Afterdepolarization - Prolonged QT and TdP
What is this?
Delayed Afterdepolarization
What is this?
Junctional escape rhythm - normal QRS, and no P wave
What is this?
Ventricular Escape Rhythm - wide QRS, no P wave
What is this?
First degree AV Block
What is this?
2nd Degree AV Block - Mobitz Type I (Wenckebach)
PR interval progressively lengthens until QRS is dropped
What is this?
2nd Degree AV Block - Mobitz Type II
QRS complex blocked without lengthening of PR interval
QRS wave can also be widened
What is this?
3rd Degree AV Block
P waves march on
QRS are widened - they originate from within distal ventricular system, not bundle of His
What is this?
Atrial Premature Beat
What is this and how do you treat it?
Atrial Flutter
Beta blocker, Ca channel blocker, digoxin
Anti-coagulate
Ablate tricuspid caval isthmus
Procainamide, Flecainide, Amiodarone - normal sinus
What is this and how do you treat it?
Atrial fibrillation
Beta blocker, Ca channel blocker, digoxin,
Cardiovert, Procainamide, Flecainide, Amiodarone
Anti-coagulate
What is this?
AV Nodal Reentrant Tachycardia
Adenosine, Beta blockers, Ca channel blockers
Ablate slow pathway
What is this?
Wolff-Parkinson-White (ventricular pre-excitation syndrome)
What is this characteristic of?
Orthodromic tachycardia - in WPW
“down slow, up fast”
What is this?
Ventricular Premature Beat
Observe/Beta blockers
What is this?
Monomorphic VT
Cardovert
Amnioddarone, procainamide, lidocaine
What is this?
Torsades de Pointes
Cardiovert, isoproterenol
What is this?
Ventricular fibrillation
