ECG Artefacts: Causes and Solutions
Understanding ECG Artefacts
Definition: Artefacts are irregularities or disturbances in ECG readings caused by patient movement or external factors.
Causes of Artefacts
Patient Movement: Moving arms and legs during the ECG recording can result in a shaky and irregular rhythm on the screen.
Electronic Devices: Presence of electronic devices, such as mobile phones, can cause interference and artefacts in the ECG.
Medical Conditions: Conditions like Parkinson's disease or tremors can contribute to artefacts in the ECG.
Minimizing Artefacts
Placement Adjustments: For patients with natural shakes or tremors, reposition limb leads closer to the trunk (e.g., from wrists to shoulders) to reduce artefacts.
Eliminating External Factors: Address potential causes such as electronic devices or ask the patient to remove objects from their pockets.
Dealing with Noisy Data
Evaluation and Communication: Assess if patient movement or external factors are contributing to noisy data. Communicate with the patient to remain still or remove interfering devices.
Lead Placement: Ensure correct lead placement to maintain accuracy in the ECG recording.
Documentation: If artefacts persist despite attempts to minimize them, document the presence of noisy data and the reasons behind it.
