RESEARCH ON THE AMPLITUDES OF ELECTROCARDIOGRAPHIC WAVES IN KIDS

Electrocardiogram (ECG) is the graphical recording of cardiac current during the cardiac revolution, which is a widely used medical examination technique, nowadays. In our research, we focused on the analysis of the obtained electrocardiograms, but also on the determination of amplitudes of electrocardiographic waves (in bipolar leads: I, II, and III, as well as in the unipolar leads: aVL, aVR and aVF). To achieve the proposed aims, we recorded electrocardiograms in healthy kids, aged 1-1.5 months, using limb leads. From our research, we can recommend the limb leads for the recording of the electrocardiogram in kids (because they give the electrocardiograms an optimal aspect and they can be analysed and interpreted easily). The maximum amplitude of the electrocardiographic waves was recorded in D I. The P wave was 0.115 +/- 0.010 mV, the QRS complex was 0.625 +/- 0.078 mV and the T wave was 0.460 +/- 0.045 mV.
