Study Notes
Cardiovascular System: History and Assessment
- Heart disease in children is a combination of genetic and environmental factors.
- Prenatal history is important, including maternal infections (possibly teratogenic) and later in pregnancy, potentially causing myocardial issues in infants.
- Maternal drug, alcohol use, and smoking may contribute to heart and other systemic problems.
- Growth is crucial for evaluating cardiovascular health; poor weight gain is often a more significant indicator in CHF than poor height increase.
- Congestive heart failure (CHF) in infants is manifested through symptoms like fatigue or diaphoresis with feeding, fussiness, tachypnea, dyspnea, feeding difficulties (prolonged), easy fatiguability, shortness of breath with exertion, and orthopnea (Older children).
- Exercise intolerance is a crucial assessment factor for these children, similar to recurrence of 'pneumonia,' 'bronchitis,' wheezing, or asthma
- A history of a heart murmur is important, but it is normal/innocent in some healthy children.
- Other cardiac symptoms include cyanosis, palpitations, chest pain, syncope, and near-syncope.
- Review of systems is needed to rule out systemic diseases and congenital heart defects.
- Family history of early atherosclerosis, congenital heart disease, sudden unexplained deaths, thrombophilia, rheumatic fever, hypertension, or hypercholesterolemia is important.
Cardiovascular System: Physical Examination
- Observations, inspection, palpation, and auscultation are used to evaluate cardiovascular status.
- Vital signs (heart rate, respiratory rate, blood pressure) are initial assessments. Normal heart rate varies with age and activity.
- Tachycardia can be caused by anemia, dehydration, shock, heart failure, or dysrhythmias. Bradycardia can be a normal finding in athletes.
- The respiratory rate is assessed, noting left-to-right shunts might cause pulmonary issues like increased respiratory rate.
- Proper cuff sizing (90% of arm circumference and 80-100% of arm length) is critical for accurate blood pressure measurements.
- Pulses are evaluated for rate, rhythm, intensity, symmetry, and timing between upper and lower extremities. A good pedal pulse, with normal right arm blood pressure, effectively rules out coarctation of the aorta.
- The precordium is checked for apical impulse (impulse at the apex of the heart), for hyperactivity, and for thrills.
- Abdominal palpation assesses liver and spleen size. An enlarged liver indicates systemic venous congestion, while splenomegaly is less commonly associated with heart failure but is still possible.
Cardiovascular System: Additional Information
- Congenital heart abnormalities are associated with a variety of syndromes; those listed include Trisomy 21, Trisomy 18, and others.
- A variety of heart sounds and murmurs are assessed; single S2 can be related to Pulmonary hypertension associated with one-way valve, severe aortic stenosis, or a condition in which a valve is not working properly. This can also be in various other configurations.
- Murmurs are categorized as systolic, diastolic, or continuous; ejection murmurs are crescendo-decrescendo, starting and ending relatively quickly, while holosystolic murmurs occur throughout the duration of systole.
- Normal findings, like the venous hum, and abnormal findings like continuous murmurs are detailed regarding their timing, location, quality, and typical age.
- The Jones criteria, used to diagnose acute rheumatic fever, also consider minor criteria such as fever, leukocytosis, elevated ESR/CRP, arthralgias, a prolonged PR interval, and a history of previous rheumatic fever, along with a typical history of strep throat, to establish a diagnosis of acute rheumatic fever.
- Echocardiography is the most specific and useful diagnostic tool.
- Common heart conditions like pericarditis are discussed, providing details on etiology, symptoms, and diagnostic testing considerations.
