Electrocardiogram01:29

Electrocardiogram

An electrocardiogram (ECG or EKG) is a critical diagnostic tool that records the electrical signals produced by the heart during each heartbeat. This recording is achieved through electrodes placed strategically on the arms, legs, and chest. The electrocardiograph amplifies these signals and produces 12 distinct tracings, offering a comprehensive understanding of the heart's electrical activity.
Three major waveforms are present in a typical ECG recording: the P wave, the QRS complex, and the T...

Purpose of the Study:

  • To develop a novel method for detecting electroencephalography (EEG) during exercise.
  • To overcome the limitations of traditional EEG measurement in dynamic conditions.

Main Methods:

  • Development of a custom algorithm for EEG signal processing.
  • Implementation of a new measurement technique for EEG acquisition during exercise.
  • Testing the method on five healthy human subjects.

Main Results:

  • Successfully measured artifact-free EEG signals in all tested subjects.
  • Demonstrated the efficacy of the developed algorithm in a real-world exercise scenario.
  • Validated the new method for capturing EEG data during physical exertion.

Conclusions:

  • The developed method enables reliable EEG measurement under exercising conditions.
  • This advancement opens possibilities for studying brain activity during physical activity.
  • The new algorithm effectively removes motion artifacts from exercise EEG data.
