Cardio Diseases Flashcards
1
Q
Romano-Ward syndrome
A
- AD
- K+ chan mut, long QT
- pure heart phenotype
2
Q
Jervell and Lange-Nielsen syndrome
A
- AR
- K+ chan mut, long QT
- heart and sensorineural deafness
3
Q
Brugada syndrome
A
- AD
- Asian males
- EKG with ST elevation and pseudo-RBBB (leading to SCD)
- tx with implantable cardioverter
4
Q
Wolff-Parkinson-White syndrome
A
- abnormal fast accessory conduction pathway from atria to ventricle bypasses rate slowing AV node
- delta wave and widened QRS
- cause reentry circuit and thus supraventricular tachy
5
Q
What is the most common type of ventricular pre-excitation syndrome
A
Wolff-Parkinson-White syndrome
6
Q
Risk factors for a. fib
A
- HTN
- CAD
7
Q
1st degree AV block
A
- prolonged PR interval (>200msec)
- benign
8
Q
2nd degree AV block (mobitz I)
A
Progressive lengthening of PR interval until a beat is “dropped”
9
Q
2rd degree AV block (mobitz II)
A
Randomly dropped beats
- can progress to 3rd-degree block (tx: pacemaker)
10
Q
3rd degree AV block
A
Atria and ventricle beat independently of each other (tx: pacemaker)
11
Q
What infectious disease can cause 3rd degree AV block?
A
Lyme disease
12
Q
How long is one big block?
A
200msec (.2 sec)
