Show Solution
The Correct Option is A
Solution and Explanation
Step 1: Recall what a J wave looks like - it is a small hump or notch right where the QRS meets the ST segment, called the J point. Step 2: Among the listed options we need the one famous for this hump. A low core temperature alters cardiac repolarization and produces this deflection, so a cold patient (core $<$ 32°C) is the textbook association. Step 3: Working through the others, potassium and calcium derangements each have their own signatures - peaked T waves with high potassium, U waves with low potassium, and a stretched QT with low calcium - but none give the J-point hump. Step 4: Therefore the single best answer here is hypothermia. \[\boxed{\text{Hypothermia}}\]
