In　ECG　signals　accurate　detection　to　the　position　of　QRS　complex　is　a　key　to　automatic　analysis　and　diagnosis　system.　And　its　premise　is　that　effectively　remove　all　kinds　of　noise　interference　in　ECG　signal.　Here,　a　method　of　detecting　QRS　based　on　EMD　and　wavelet　transform　was　presented　which　is　aim　to　improve　the　anti-noise　performance　of　the　detection　algorithm.　It　is　combined　EMD　with　the　theory　of　singularity　detecting　based　on　wavelet　transform　modulus　maxima　method.　It　has　the　high　detection　accuracy　and　good　precision　that　can　give　an　effective　way　to　the　automatic　analysis　for　ECG　signal.　©　(2013)　Trans　Tech　Publications,　Switzerland.
