Key Points Any wide QRS (>90 ms) in an infant or small child is abnormal and should trigger evaluation for VT, sodium-channel blockade, or conduction disease. QTc >450 ms in…
Key Points ECG rhythms in pediatric arrest differ from adults. Pulseless arrest in children is most often asphyxial, but ECG clues can reveal reversible metabolic, toxicologic, or structural causes. Wide…
Key Points Pediatric ECGs are not scaled-down adult ECGs. Right axis deviation, large R waves in V1, and T wave inversions in V1 to V3 are expected in healthy children….
