Description
Chenhui Tai and Zhe Wang ask whether the shape of a heart signal across chest leads foretells death, in a 2026 study. The J point is a notch in the heart's electric trace, long deemed harmless in its early-rise form. The team drew on a US health survey of adults aged forty to ninety. None reported a heart attack or heart failure. They grouped how the notch's height moves across three left chest leads.
Two patterns emerged. Most people showed a low, gently falling pattern. A smaller group showed a high start and a steep fall. Over a median follow-up of about twenty-five years, the steep group faced higher odds of death overall and of heart death. The authors say the pattern adds warning beyond standard readings, pending outside checks.
