I showed this text to a friend who works in internal medicine (so not a cardiologist but probably much closer than most commenters). Basic comment was that the person confuses and misunderstands many things. According to my friend, the range marked as "missed beat" contains a premature heart beat [1]. Some more comments: - Premature hear beats happen in us quite frequently - CT scans are a rather invasive diagnostic method and such be avoided So unless some more competent doctor comments otherwise, I take this as a nice story that resonates well in our layperson's minds. Not more. [1] https://en.wikipedia.org/wiki/Premature_heart_beat https://en.wikipedia.org/wiki/Premature_heart_beat
