ECG

ECG / EKG Signal

Electrocardiography (ECG or EKG) is the study of the heart's electrical activity, most commonly recorded via placement of electrodes on the skin. Human and animal ECG signals can be recorded for easy processing of heart rate, heart rate variability, analysis of the waveform morphology, and similar functions.

ECG Signal Overview

The sinoatrial (SA) node acts as the pacemaker of the heart. These cells rhythmically produce action potentials that spread through the muscle fibres of the atria and ventricles. The resulting contraction pushes blood into the ventricles, and then out into the vasculature.
Innervation by the parasympathetic and sympathetic nerves can modify the basic cardiac rhythm e.g. as occurs in sinus arrhythmia. Similarly, heart rate can be influenced by activity of the sympathetic nervous system due to change in emotional and cognitive state.

Enabling Discovery

LabChart

All your analysis in one place

LabChart software is designed specifically for life science data and provides up to 32 channels for data display and analysis options that are powerful and easy to use. With auto-recognition of ADI and LabChart Compatible hardware, multi-window views, one touch recording, simultaneous recording from multiple devices, specialized preconfigured settings, easy sharing options and an interface that can be customized to show only the features you want to use.

ECG Electrode Placement

To reduce noise in your ECG recording, avoid placing electrodes over large muscle groups e.g. Biceps, where possible.

ADInstruments Bio Amps also provide flexible settings (range, filters) which allow you to detect small changes in ECG that may not be detected in clinical ECG machines. The same Bio Amp can then also be used to record other biopotentials such as EEG, EMG and EOG.
