Electrocardiogram lead iii

Simple 2D ECG trace labeled lead III, drawn as a thin dark waveform on a horizontal baseline. The tracing includes a QRS complex that is mainly positive but has a noticeable negative portion, making it visually distinct from lead I. The lead is clearly identified with the Roman numeral III in clean black clinical lettering beside or near the trace.
