4 topics with concise reviews: definitions, key facts, and class questions.
Welcome to pediatric cardiology, one of the most complex and critical fields in pediatrics. Here we study cardiovascular pathologies that can manifest in a child either during the neonatal period or in puberty.
The chapter consists of four key topics. We will analyze the hemodynamics and auscultatory findings of congenital heart disease (CHD), as well as the classification and ECG diagnosis of cardiac arrhythmias. You will also find clear diagnostic algorithms for acute rheumatic fever (recalling the Jones criteria) and modern approaches to the management of arterial hypertension in children and adolescents.
Practical classes and exams most frequently test the differential diagnosis of cyanotic and acyanotic CHD, as well as the ability to distinguish functional (age-related) arrhythmias from life-threatening conditions. Read carefully: there are no "trivial" topics here, as this knowledge is applied daily in real clinical practice.
How to distinguish functional extrasystoles from organic ones?
Functional extrasystoles are more frequently of supraventricular origin, characterized by variability, and typically disappear or significantly decrease with physical exertion.
What early signs can suggest CHD in a newborn?
First and foremost, these include transient or persistent cyanosis, tachypnea (shortness of breath), pallor, poor weight gain, edema, and the detection of a harsh systolic murmur radiating to the back.
At what age do people most frequently develop ARF?
The disease has strict age specificity: the vast majority of cases debut in childhood and adolescence, between 7 and 15 years of age. Primary development of ARF in adults is a rarity.
Can essential hypertension be diagnosed in a 12-year-old child?
Yes, but only as an exception, if target organ damage (heart, kidneys, eyes) has already been instrumentally confirmed. As a standard rule, this diagnosis is established from 16 years of age with persistent hypertension lasting at least a year.
