ConceptECG recording
DescriptionAn electrocardiograph (ECG or EKG) is an interpretation of the electrical activity of the heart over time, recorded non-invasively using external skin electrodes.
UseUse to record details of a standard 12 lead ECG including parameters and interpretation. Use to record details of ECGs performed during exercise conditions and stress testing.
MisuseNot to be used for recordings with non-standard ECG leads. Not to be used for recording Holter monitor results.
PurposeTo record the electrocardiographic interpretation of the electrical activity of the heart by an ECG device.
