Pediatric Arrhythmias

Show Summary Details


Although the mechanisms of dysrhythmias in pediatric and adult patients are usually the same, the clinical presentations and management plans may vary considerably. Many aspects of the pediatric ECG such as QRS axis, PR interval, and ventricular hypertrophy voltages are age dependent; therefore, a table of normal values based on age is necessary when evaluating ECGs from pediatric patients. In addition, heart rates are much faster in children, with resting heart rates up to 160 beats per minute being common in children younger than 1 year. The maximum sinus heart rate is also faster in younger patients, with the maximum rate typically being 220 beats per minute minus the age. This is an important fact to note when distinguishing sinus tachycardia from pathologic arrhythmias in this age group. This chapter reviews the salient features of most pediatric dysrhythmias, including their management.
