Accelerated Ventricular Rhythm
Accelerated Ventricular Rhythm An accelerated ventricular rhythm is a less common arrhythmia. There is a wide QRS rhythm, generally at a rate not more than 10% greater than the underlying…
Sinus Arrhythmia
Sinus Arrhythmia Sinus arrhythmia is the most common cause of an irregular heart rate and rhythm, that is more prominent at slower heart rates, such as in older infants. It…
Cyanotic Lesions
Cyanotic Lesions The differential diagnosis of cyanotic heart disease includes many disorders (Table 33-12). Lesions usually associated with decreased pulmonary flow include the tetralogy of Fallot, pulmonary stenosis, tricuspid atresia,…
Arrhythmias
Arrhythmias All forms of cardiac arrhythmias can occur in the fetus or newborn. Those most commonly encountered include sinus tachycardia and bradycardia, premature atrial depolarizations, supraventricular tachycardia; and less commonly,…
Acyanotic Anomalies with Abnormal Cardiac Function or Structure
Acyanotic Anomalies with Abnormal Cardiac Function or Structure Cardiomyopathy Sick neonates without cardiac anatomic anomaly often develop symptoms of cardiac and myocardial dysfunction. Systolic and/or diastolic dysfunction most often occur…
Acyanotic Lesions
Acyanotic Lesions Acyanotic diseases associated with normal pulmonary flow include those with systemic outflow obstruction such as coarctation of the aorta and aortic stenosis, mild and moderate pulmonary outflow stenosis,…
Management Procedures for Severe Cardiac Disease
Management Procedures for Severe Cardiac Disease Preprocedure An infant in difficulty in the first days of life because of heart disease has the potential for rapid deterioration. Too often, the…
Diagnostic Cardiac Catheterization and Angiography
Diagnostic Cardiac Catheterization and Angiography Anatomy Catheterization is rarely used to learn the basic anatomy of the heart. The diagnostic information necessary for most cardiac surgical procedures in neonates is…
Diagnostic Tools
Diagnostic Tools Chest Radiography Chest radiography is rarely diagnostic of specific cardiac lesions, but it is a relatively quick and relatively inexpensive method to identify lung disease and screen for…
Recognition of Clinical Features
Recognition of Clinical Features Only a few infants are born in hospitals equipped for all eventualities. Infants with serious heart anomalies require transportation to a specialized pediatric cardiac center for…
