The ‘Q’ is a term representing the releasing of chemically generated electricity in the heart. Each Q on the cardiac wave, the heartbeat, is followed by an R, an S, and a T, then a P, followed by another Q, in a healthy organism.
No Q, no health.
Any simple search of the QRS will reveal information regarding cardiac activity.
Nobody ever mentions it out here, so, I randomly post on occasion.
That is interesting.
