Question 1: What is the diagnosis of the FLB (funny-looking-beat) in this Lead V1 ECG rhythm strip?

What is the diagnosis of the FLB (funny-looking-beat) in this Lead V1 ECG rhythm strip?
A. It's a PAC with LBBB aberration
B. It's a PAC with RBBB aberration
C. It's a PVC from the right ventricle
D. It's a PVC from the left ventricle

Question 2: In this V1 rhythm strip, what does the 'F' imply?

In this V1 rhythm strip, what does the 'F' imply?
A. 'F' is for "Funny-looking-beat"
B. 'F' is for "failure-to-capture" which implies the sinus P wave can't get into the ventricles.
C. 'F' is for "fusion beat"; i.e. the fusion of a right ventricular PVC with the sinus initiated QRS complex.
D. 'F' is for "fusion beat"; i.e. the fusion of a left ventricular PVC with the sinus initiated QRS complex.

Question 3: In this V1 rhythm strip look at the wide QRS rhythm. Why do the RR intervals vary?

In this V1 rhythm strip look at the wide QRS rhythm. Why do the RR intervals vary?
A. This is a ventricular tachycardia with intermittent 2:1 exit block.
B. This is paroxysmal atrial fibrillation with RBBB aberrency.
C. This is a ventricular escape rhythm alternating with ventricular tachycardia.
D. This is sinus rhythm with a rate-related right bundle block.

Question 4: In this V1 rhythm strip there are 4 FLB's (Funny-looking-beats) in addition to the normal sinus beats. What are they?

In this V1 rhythm strip there are 4 FLB's (Funny-looking-beats) in addition to the normal sinus beats. What are they?
A. These are multifocal PVCs
B. The first FLB is a late onset PVC, and the other three are fusion beats.
C. Intermittent right bundle branch block (RBBB)
D. Intermittent WPW type preexcitation

Question 5: In this V1 rhythm strip, what degree of AV block (if any) is present?

In this V1 rhythm strip, what degree of AV block (if any) is present?
A. 1st degree AV block
B. 2nd degree AV block
C. 3rd degree AV block
D. No AV block; this is complete AV dissociation

Question 6: In this V1 rhythm strip, what do the 'e' and 'c' represent

In this V1 rhythm strip, what do the 'e' and 'c' represent
A. The 'e' represents a ventricular echo beat form the nonconducted P wave. The 'c' is a sinus capture.
B. The 'e' is for ventricular escape. The 'c' is a PAC.
C. The 'e' is a junctional escape, and 'c' represents a PAC.
D. The 'e' represents a junctional escape beat; the 'c' represents a sinus capture.
