Figure 3From: Ventricular beat detection in single channel electrocardiogramsCorrect VB detection with some exceptions. A QRS complex is early detected as EB because of muscle disturbances between the 768th and 769th s of AHA 6003d2. Normal QRS complexes after 22nd and 28th s in AHA 2008d1 are marked erroneously as EBs. Difficult EBs with compensatory pause are detected in AHA 5001d1, except for the low amplitude EB after the 258th s.Back to article page
