Why are heartbeat rhythms unique?
SCIENCE
Because enquiring minds need to know…
◼ The simple answer to this question is ‘physiology’. In other words, an individual’s heartbeat comes down to their heart’s shape. Contrary to popular belief, not everybody’s heart looks exactly the same. They are not only different sizes, but also different shapes, with the all-important valves positioned in their own distinctive way. This affects the tempo of the heartbeat. The shape, and therefore rhythm, of your heart won’t change unless you have a major heart attack.
