This article describes how to report J-Tpeak using Ponemah.
Placement of ECG Marks
To obtain the J-Tpeak interval in Ponemah:
- Place the Send mark on the J point.
- Use ECG PRO for Send mark placement on additional cycles.
- Enable the Tpe derived parameter to provide the J point to Tpeak interval in milliseconds.
The equation would then be:
J-Tpeak Interval (msec) = QT interval – QRS width – Tpeak
This equation can be entered in Ponemah's Custom Derived Parameter or by using the Excel output to compute.
