Two types of ECG signals (normal and abnormal) can be detected in this work from each database. The records from MIT-BIH Arrhythmias and Apnea ECG database from physionet have been used for training and testing our neural network based classifier. 90% healthy and 100% abnormal are detected...
For these reasons, the ECG must be regarded as any other laboratory test, with proper consideration for both its uses and its limitations (see Chapter 23). The 12 ECG leads are described in Chapter 3. Normal and abnormal ECG patterns are discussed in subsequent chapters. View chapterExplore ...
Changes in the Electrocardiogram During and After Exercise Although differences in the waveforms between horses with normal and abnormal resting ECG's have been observed, the more definitive useful information is the fact that abnormal horses showed significantly higher heart rates than normal horses......

To this end time-frequency distributions for simulated normal and abnormal ECG waveforms were obtained. Then features representing the normal waveform were extracted and used to train a classifier. Finally the performance of the classifier in detecting arrhythmias was tested using unknown ECG waveforms....
This chapter focuses on the physiological electrocardiogram (ECG) adaptations commonly found in athletes to help guide physicians when distinguishing between normal ECG adaptations and abnormal ECG findings associated with pathological cardiac conditions. In athletes, resting sinus bradycardia is a common ...

Research interest has been largely directed towards the abnormal heart and there is a relative paucity of information on the "normal". Some reliance therefore has to be placed on control groups which in a number of instances are lacking in detail. There is a wide variation in the literature ...
Participants were asked to classify recordings as normal, abnormal, or not possible to evaluate (noisy/uncertain). The overall score for an entry was based on a weighted sensitivity and specificity score with respect to manual expert annotations. A brief description of a baseline classification ...
Why is an ECG sometimes called an EKG? The heart A patient's ECG tracing shows a consistent pattern on two P waves followed by a normal QRS complex and T wave. a. What is the cause of this abnormal wave pattern? b. What signs might the patient exhibit? What is the EKG? Explain th...
