can someone tell me what does this mean. How is this difference from normal ECG


Hi Sakina,

An EKG or ECG measures heart chamber sizes by determing lenght of interval (in msec) on the horizontal axis. There is an acceptable dimension range for a chamber size, and if the value is slightly outside the range, it could be classified borderline abnormal.

But any EKG output is inconclusive and requires further testing to substantiate.
