ECG J-Tpeak interval calculation using Ponemah

To obtain the J-Tpeak interval in Ponemah:

1. Place the S_end mark on the J point.
2. Use ECG PRO for S_end mark placement on additional cycles.
3. Enable the Tpe derived parameter to provide the J point to Tpeak interval in milliseconds.
4. Use Ponemah Excel output to calculate:
   J-Tpeak Interval = QT interval – QRS width – Tpeak
   Output will be in milliseconds
