Fetal Arrhythmias

Question 1

Normal FHR

Answer 1

120-180 bmp

Question 2

Any heart rate that is irregular or outside the normal range

Answer 2

Fetal arrhythmia

Question 3

Most common fetal arrhythmia

Answer 3

PAC

Question 4

Premature contraction of the atria followed by premature contraction of the ventricle

Answer 4

Conducted PAC

Question 5

Premature contraction of the atria followed by absence of the ventricular contraction

Answer 5

Non-conducted PAC

Question 6

Can progress to supraventricular tachycardia

Answer 6

PAC

Question 7

Premature contraction of the ventricular that is not preceded by a premature contraction of the atria

Answer 7

PVC

Question 8

Atrial rate of SVT

Answer 8

180-299 bpm

Question 9

Heart rate of an atrial flutter

Answer 9

300-500 bpm

Question 10

Ventricular conduction rate of a SVT

Answer 10

1:1

Question 11

Fetal heart rate >180 bpm with a 1:1 ventricle conduction rate

Answer 11

SVT

Question 12

This heart defect is associated with SVT

Answer 12

Einstein anomaly

Question 13

If RP interval is shorter than PR interval

Answer 13

Consider “re-entrant” tachycardia,
Wolff-Parkinson white syndrome

Question 14

If RP interval is longer then PR interval

Answer 14

Permanent junctional reciprocating tachycardia, more difficult to treat, higher mortality

Question 15

Conduction rate with an atrial flutter

Answer 15

Variable, 2:1 or 3:1

Question 16

Associated with Long QT syndrome

Answer 16

Ventricular tachycardia

Question 17

Ventricular rate >180 bpm and exceeds normal atrial rate

Answer 17

Ventricular tachycardia

Question 18

Atrial & ventricular rate > 180 bpm =

Answer 18

SVT

Question 19

Only Ventricular rate > 180 bpm =

Answer 19

VT

Question 20

Heart rate below 120 bpm

Answer 20

Bradycardia

Question 21

Sustained bradycardia =

Answer 21

Heart block

Question 22

Prolonged PR interval (>150 msec)

Answer 22

1sr degree heart block

Question 23

Ventricular rate <120 bpm, 2:1 3:1 conduction rate

Answer 23

2nd degree heart block

Question 24

Ventricular rate <120 bpm, complete dissociation of atrial/ventricular rates

Answer 24

3rd degree (complete) heart block

Question 25

Atria - normal beat followed by a PAC Ventricle- regular and slow

Answer 25

Atrial bigeminy

Question 26

Atria - normal and regular Ventricle - independent and slow

Answer 26

2nd degree heart block

Question 27

Most common structural abnormalities associated with a CHB

Answer 27

Left atrial isomerism CC-TGA AVSD

Question 28

Lupus

Answer 28

CHB +SSA /Ro antibodies
