Assessment of current pediatric electrocardiogram (ECG) interpretation practices

Abstract

BackgroundDespite improvements in digital electrocardiograms (ECGs), current standard of care requires physician confirmation. Mismatched expectations between ordering providers and ECG readers, often pediatric cardiologists and electrophysiologists (EPs), are common, especially since there are no standardized practices for pediatric ECG reading. ObjectivesThe aim of this study was to understand current practices in pediatric ECG reading. MethodsAn electronic survey was sent to members of the Pediatric and Congenital Electrophysiology Society (PACES). Participation was optional; results were recorded from 12/19/22–1/9/23. Only complete and non-duplicate entries were included. ResultsA total of 127 responses were received, 93 were analyzed. Most responses were from centers in North America (n = 65, 70 %), including the US (n = 58, 62 %), Canada (n = 6, 6 %), and Mexico (n = 1, 1 %). The remaining were from Europe (n = 18, 19 %), Asia (n = 7, 8 %), Australia (n = 2, 2 %), and South America (n = 1, 1 %). Most (n = 46, 49 %) were from small centers (0–25 ECGs read per day), 27 respondents (29 %) were from medium centers (26–50 ECGs read per day), 20 respondents (22 %) were from large centers (>50 ECGs read per day). The majority (n = 65, 70 %) reported >3 readers/day for inpatient and emergency department ECGs. 49 % (n = 46) of centers read ECGs >2 times/day on weekdays with more variable practice on weekends. For critical/time sensitive findings, most centers (n = 90, 97 %) used verbal communication +/− the EMR. There was consensus (≥50 % agreement) that the following findings are critical/time sensitive: QTc >500 ms, T-wave alternans, narrow complex tachycardia, wide complex tachycardia, pre-excited atrial fibrillation, focal ischemic changes, second degree heart block type II, complete heart block, and pacemaker malfunction. ConclusionReading practices are variable. Critical/time sensitive findings are most often communicated verbally, however, there is no agreed upon standard. There was consensus in critical/time-sensitive findings. Improved understanding of common practices and resource allocation may lead to increased consistency in pediatric ECG reading.
