 ## Adding distortions to the synethic images
 - ### Text distortions
      Scanned ECG images often contain handwritten notes by physicians, sometimes overlapping the ECG traces. Our toolkit simulates this by using a dictionary of relevant keywords, which are randomly placed on the ECG images. We gathered medical texts related to ECG and cardiovascular diseases and employed Natural Language Processing (NLP) models to extract biomedical phrases and keywords. These were transformed into handwritten-style images using pretrained models and overlaid on the ECG images.
