Web4 jun. 2024 · If the intervals vary by less than 0.06 seconds or 1.5 small boxes, then the rhythm is considered to be regular. And if the intervals between the R waves (from R to R) are variable by greater than 0.06 seconds or 1.5 small boxes, then the rhythm is considered to be irregular. WebLet’s say that there are 4 big boxes and 1.5 small boxes between two R waves, meaning there are 4 x 5 + 1.5 = 21.5 small boxes, and that means there’s 0.04 seconds x 21.5 or .86 seconds between heartbeats. Now, to get something a little more meaningful we can take the inverse which is 1 over 0.86 beats per second, or 1.16 beats per second.
