fetus tachycardia
HR 160-180
fetal tachy assoc. w/ materna
hyperthyroidism
medications
fetal tachy assoc. w/ fetal
in utero infection
fetal anemia
hypoxia
chromosomal anomalies with fetal tachy
tri 13
turners
fetal bradycardia
HR <80 bpm
ectopic beats may be induced with
ETOH
Caffeine
nicotine
what should the axis of the heart be
45 degrees
how much of the chest should the heart occupy
1/3rd
4 chamber view
left atrium closest to aorta and spine
what does the short axis view of the heart shore

RVOT image
fetal VSD
most common
usually isolated
ASD strong assoc. w/ which trisomy
21
hypoplastic LV
left side more common
unaffected side enlarged
hypoplasia of great vessel of affected side
sono findings of hypoplastic LV
vis. one side of heart
small ventricle and atrium
may have hydrops
tetralogy of fallot
large VSD
pulmonic stenosis
RVH
overriding aorta
tetralogy of fallot assoc. w/ which trisomy
21
ebsteins anomaly
TV towards apex
ebsteins anomaly assoc. w/
pulmonary atresia
av canal
transposition of great vessels
arrythmias
coarctation AO
tetralogy of fallot
transposition of great vessels
complete most common
AO rises from RT vent
assoc. w/ vsd ASD PDA
truncus arteriosis
primitive truncus fails to partition and separate
truncus arteriosis
VSD GU anomalies Situs inversus Asplenia
univentricular heart
2 atria connected to single vent.
double outlet RT ventricle
both great vessels arise from RT vent
cardiac neoplasms
rhabdomyomas or sarcomas
echogenic
poor prognosis
