Once detected the NN interval, defined as the Normal-to-Normal interval obtained from the signal without abnormal beats, several features related to HRV were extracted (Table 1): linear statistical and geometric features, and nonlinear features (T. F. of The European Society of Cardiology et al...
[42-51] All the obtained reading are compared with the normal reading of a subjects and some references i.e Dr.Bllams and Dr.Johnsons quotsons. TheECGabnormalities are detected by measuring and comparing P-R‚ QRS and Q-T intervals with normal values. Below the table is a normal ...
0.73% error rate is achieved means 32 ECGs are misclassified out of 4366 ECGs. Results on PTBDB ECG Database are shown in Table9. The values of the parameters\({m}_{l}\),\({\mathbb{C}}_{\mathcal{R}}\)and\({\rm P}_{\rm K}\)are also shown in the table...
[63]. Table 2 displays the standard values for these intervals, considering a healthy human being with no cardiac abnormalities. Table 2. Typical feature of a normal ECG signal, with a cardiac frequency of 60 beats per minute (bpm) of a healthy adult. FeatureNormal valueNormal variation P ...
Full size table Conclusion In this paper, we propose a general model based on the two-dimensional ECG and DSE-ResNet to realize the automatic classification of normal rhythm and 8 cardiac arrhythmias. The two-dimensional processing method combines the original 12-lead ECG into the same two-dimen...
Cardiology experts annotated those rhythm files separately, primarily categorizing them into five types, including normal beats (N), atrial premature beats (A), premature ventricular contractions (V), left bundle branch block (L), and right bundle branch block (R), as shown in Supplement Table ...
Records were distributed into five classes, with each class having 100 records, as shown in Table 2. Table 2. Details of classes in the dataset. ClassDescriptionIncluded beatsNumber of extracted records N Non-ectopic beats Normal beats, left bundle branch block, right bundle branch block, nodal...

\(Ku\) indicates whether the RR intervals data is flat or peaked distribution in comparison with the normal distribution, while \(Sk\) measures the tails asymmetry of the RR data distribution. Table 1 shows the HRV time domain measures for \(M\) successive RR intervals with interval length ...
Table 4 Number of ECGs for the different classes over the four datasets in the used datapool. NSR, normal sinus rhythm; ST, sinus tachycardia without other annotations; SB, sinus bradycardia without other annotations. Full size table Moreover, the amount of normal sinus rhythm, sinus tachycardia...
