Electrocardiogram Delineation in a Wistar Rat Experimental Model

Figure 3

Box and whisker plots showing the mean (a) and standard deviation (b) values for different ECG parameters in Wistar rats. The ECG parameters measured were the RR interval (RR), QRS duration (QRS), QT interval duration (QT), and T-wave peak-to-end duration (TPE). The temporal analysis based ECG delineator () was represented with clear boxes and the wavelet transform based ECG delineator () was represented with dark boxes. , , and indicate statistically significant differences of ECG parameters between and . NS: nonstatistically significant differences between both groups.
