Key Points: Pediatric arrest is usually respiratory, hypoxic, or shock-related, not primary coronary occlusion. The ECG still matters because it can reveal reversible metabolic, toxicologic, structural, inflammatory, or inherited electrical…
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: 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….
Key Points: Persistent juvenile T wave pattern is a benign normal variant that most often appears as shallow asymmetric T wave inversion in the right precordial leads, usually V1 to…
An elderly male presents with weakness and lightheadedness to his primary care physician. He is referred to the ED after the following ECG is obtained:
