This invention discloses a method and a device for dynamically acquiring ECG signal. The device comprises an ECG signal acquisition circuit a static unit carrying a second electrode connected to the ECG signal acquisition circuit and a dynamic unit having a first electrode connected to the ECG signal acquisition circuit and a non-electrode part. When performing ECG signal acquisition, the static unit is fixed to a part of the body of a subject to make the second electrode contact the skin, and the non-electrode part of the dynamic unit is held by an operator to make the first electrode contact the skin of another part of the subjects body. Afterwards, an ECG signal acquisition process is executed to obtain the ECG signal of the subject with a projection angle between two points of the first electrode and the second electrode. Furthermore, the obtained ECG signal or other related ECG messages are instantly displayed on an external device.本發明所揭示為一種動態心電訊號擷取方法及裝置,該裝置包括一心電訊號擷取電路,一靜態單元,承載有連接至該心電訊號擷取電路的一第二電極,以及一動態單元,具有連接至該心電訊號擷取電路的一第一電極,以及一非電極部分,當進行心電訊號擷取時,該靜態單元被固定於一受測者身體的一部份,以使該第二電極接觸皮膚,並藉由一操作者手持該動態單元的該非電極部分而使該第一電極接觸該受測者身體另一部份的皮膚,之後,一心電訊號擷取程序被執行,以取得該受測者於該第一電極以及該第二電極兩點間之投影角度的心電訊號,並且,所取得的心電訊號或其他心電相關訊息被即時顯示於一外部裝置上。100‧‧‧心電訊號擷取電路202‧‧‧第一電極302‧‧‧第二電極
