Cardiology Flashcards
x ray findings CHD
cardiomegaly
overcirculation- prominence of pulmonary vasculature
characteristic shapes
CXR transposition of the great arteries
egg on a string
CXR T of F
boot shaped heart
Differential pulses (weak LE)
coarctation of the aorta
Bounding pulse = run-off lesions
L-R PDA
weak pulses
cardiogenic shock
pulsus paradoxus
an exaggerated SBP drop with inspiration → tamponade or bad asthma
pulsus alternans
altering pulse strength → LV mechanical dysfunction
sound of closing of mitral and tricuspid valves
S1
sound of closing of aortic (A2)and pulmonic (P2) valves
S2
sound heard in diastole ,related to rapid ventricular filling , can be normal, or abnormal -accentuated with dilated ventricles
S3
sound late in diastole just before S1 – always bad
S4
Heart murmurs which occur in the absence of anatomic or physiologic abnormalities of the heart or circulation
innocent or benign murmur
when would you hear ejection click
AS or PS
when would you hear mid systolic click
MVP
when would you hear loud S2
pulmonary HTN
when would you hear a single S2
one semilunar valve (truncus), anterior aorta (TGA), pulmonary HTN
when would you hear a fixed, split S2
ASD, PS
when would you hear a gallop
may be due to cardiac dysfunction/ volume overload
Functional murmur: heard first days of life, LLSB , 1-2/6 , gone by 2-3 weeks of life
Newborn
Functional murmur often in newborn period from branching PA. Heard in axillae and back short, high pitched 1-2/6
peripheral pulmonary arterial stenosis
Functional murmur: most common murmur of early childhood. Heard ages 2-7yrs. Musical, vibratory, mid to lower LSB, 1-3/6. loudest when patient supine
Still murmur
when would you hear muffled heart sounds or a rub
pericardial effusion ± tamponade
Functional murmur: most common innocent murmur in older children, ages 3 yrs and up. ULSB, soft ejection murmur , 1-2/6.
Pulmonary ejection murmur
Functional murmur: heard after age 2, infraclavicular R>L, Continuous musical hum. Best heard sitting. Comes from turbulence at confluence of subclavian and jugular vein
Venous hum
Functional murmur: older child and adolescent. Rt supraclavicular area, harsh, 2-3/6
Innominate or carotid bruits
syncope in kids is usually due to
Vasovagal or neurocardiogenic factors
circulation, cardiac disease less common
common origin of chest pain in kids
musculoskeletal
rarely cardiac in origin
most common rhythm disturbance in kids
PAC Some conducted, some non-conducted. Slight not-quite compensatory pause before next beat. Benign
less common rhythm disturbance in kids…wide QRS, no compensatory pause, typically benign unless they come several in a row
PVC
Supraventricular tachycardia ddx
re-entrant tachycardia (wolff-parkinson-white)
prolonged QTc syndrome
How do you stop re-entrant tachycardia
Adenosine
how do you manage re-entrant tachycardia
beta blockers
this heart block is associated with a prolonged PR
first degree
what can maternal lupus cause
congenital heart block (3rd degree)
this heart block happens when not all P waves are conducted
second degree
heart disease in children is commonly
congenital heart disease due to structural abnormalities
