[Done] 11. What are common types of ECG artifacts, and how can they be identified in a tracing? 12. How can patient movement contribute to artifacts on an ECG, and what steps can be taken to minimize this? 13. In which ways can electrical interference from nearby devices affect ECG readings? 14. What role does poor electrode placement play in generating artifacts, and how can proper technique improve signal quality? 15. How can muscle contractions or tremors lead to artifacts in the ECG, and what patients are most at risk for this? 16. What types of skin conditions or preparations can cause diminished electrode adhesion, leading to artifacts? 17. How does baseline wander manifest in an ECG recording, and what might be the underlying causes? 18.
