ECG FIle FORMAT From the THEW
ECG File Format:
The ECG signals can be extracted from the THEW Client application in ASCII, ISHNE of XML FDA HL7 format. The ACSII file format is organized so each column contains each lead of the file. To read the Holter ECG ISHNE format please refer to the description provided here. Example of files produced by the THEW Client Application are provided below.
ECG ANNOTATION Format:
The annotation information from the Holter ECG signals can be extracted from the THEW Client application in binary format following the annotation format described here or in ASCII format. The available cardiac beast anoation are defined as follow:
