  • Electrophysiology

Context:

  • Conventional 12-lead ECG provides limited spatial information.
  • Body surface potential mapping utilizes numerous electrodes for comprehensive cardiac electrical data.
  • Understanding cardiac electrical activity is crucial for diagnosing heart conditions.

Purpose:

  • To present body surface potential mapping as an advanced ECG technique.
  • To highlight the diagnostic capabilities of isopotential maps.
  • To explore the potential of this technique for future cardiac research.

Summary:

  • Isopotential maps display cardiac potential distribution across the body surface.
  • This technique visualizes the movement of cardiac electrical generators (dipoles).
