ElectroCardiography (ECG)

Electrocardiography (ECG) unveils the intricate dance of the heart through the creation of an electrocardiogram (ECG or EKG). This visual representation illustrates the voltage fluctuations over time, capturing the heart’s electrical activity. By strategically placing electrodes on the skin’s surface, ECG records the nuanced electrical changes accompanying the cardiac muscle’s depolarization and subsequent repolarization during each heartbeat.

The ECG wave recorded with Neuphony EXG Synapse can be found in the following figure.

Electrooculography (EOG)

Electrooculography (EOG) emerges as a sophisticated method for gauging the corneo-retinal standing potential, a dynamic electrical charge bridging the front and back of the human eye. The consequential signal derived from this technique is aptly labeled EOG.

The EOG wave recorded with Neuphony EXG Synapse can be found in the following figure.

Electromyography (EMG)

Electromyography (EMG) stands as a sophisticated technique designed to assess and document the intricate electrical activity generated by skeletal muscles. This diagnostic marvel extends beyond, offering a profound examination of muscle health and the neural pathways governing them, specifically the motor neurons. EMG findings unravel potential issues related to nerve function, muscular well-being, or disruptions in the communication between nerves and muscles.
