Distinguishing Normal and Abnormal ECG Signal

Variant Maps on Normal and Abnormal ECG Data Sequences

ECG data sequences are classical and most reliable clinical data for patients to provide complex physiological and pathological information diagnosing various heart diseases. Extracting dynamic information from ECG signal time sequences, Poincare maps have developed as classical assistant tools using two dimension maps as important basis for medical doctors to diagnose multiple cardiovascular d...

reference electrode (3). The ionized calcium concentration of sequential retentates prepared by ultrafiltration of a human control serum increased with increasing protein concentration in a way consistent with Donnan theory (4, 5) when the analyzers’ standard reference-electrode liquid junctionswere used; however, the ionized calcium in the same retentates declined slightly with increasing prot...

Abnormal ECG, Seizures, and Associated Neurological Deficits.

In the early 1980s, a 17-year-old girl and her mother were referred to me. The mother had a life-long history of seizures—ultimately well controlled with phenytoin—but she had never had an ECG. Her daughter began to have seizures in late childhood, several times per year, 1 of which was particularly prolonged and left her with a new, permanent neurological disorder impairing motor skills, compr...

The Abnormal vs. Normal ECG Classification Based on Key Features and Statistical Learning

Electrocardiogram (ecg) Signal Processing

Signal processing today is performed in the vast majority of systems for ECG analysis and interpretation. The objective of ECG signal processing is manifold and comprises the improvement of measurement accuracy and reproducibility (when compared with manual measurements) and the extraction of information not readily available from the signal through visual assessment. In many situations, the EC...
