We attempted to develop measurement software of electrocardiogram (ECG) with the real time processing functions such as signal monitoring, calculation of instantaneous heart rate (IHR), spectrum analysis of ECG and IHR. The signals are measured by general sound-board on PC using DirectX. Thus, the cost of the measurement system can be cut down and software has versatility and expansivity on the Windows operating systems. The sampling frequency can be arbitrarily selected at some values (100 to 48k Hz) that depend on the kind of other cardiac signals (e.g. blood pressure). Additionally, this software can calculate the IHR with high accuracy compared with previous software, because we use new R-wave detecting method in the ECG. Developed software is actually used ECG measurement in our laboratory. In the future research, we would like to improve additional functions, for example, digital filter and to detect abnormal development of the chick embryo.
