Einthoven developed a rather simple method of correction (1894) and could with this derive the actual electrocardiogram from the capillary electrometer curve
Einthoven pointed out, however, that not only the amount of the deflection but also the shape of the entire electrocardiogram is changed when one manner of leading is replaced by another (1908).
Einthoven said in his work in 1895 that the efforts to fully interpret the electrocardiogram should be abandoned for the moment, and in a survey of the relevant literature up to the first half of 1912, the author** put emphasis on the uncertainty of the efforts to interpret the cardiogram.
It is also necessary to avoid certain medications that lengthen the QT interval on the electrocardiogram, which is the portion that measures how long it takes for the heart to "recharge."
Based on several large studies that demonstrated CRT can save lives and prevent hospitalization among heart-failure patients, professional guidelines were developed that recommend its use based in part on a measurement recorded by an electrocardiogram called the QRS duration.
