Wandering baseline<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Explanation:<\/h3>\n\n\n\n<p>When a patient talks during an electrocardiogram (ECG), one of the most common artifacts that can occur is a <strong>wandering baseline<\/strong>. This artifact occurs due to the movement of the patient&#8217;s body, including the chest, diaphragm, and muscles, as a result of the patient\u2019s speech or breathing. As the patient talks, their chest and abdominal muscles move slightly, which can cause shifts or drifts in the baseline of the ECG tracing. This motion is picked up by the electrodes and leads to a wandering, erratic baseline that distorts the heart\u2019s electrical signals.<\/p>\n\n\n\n<p>Here\u2019s why other options are less likely:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>a. Somatic tremor<\/strong>: This artifact is typically caused by muscle contractions or tremors (often from shivering or involuntary muscle movements), and it results in rapid, high-frequency spikes on the ECG. It\u2019s more associated with conditions like shivering or tremors rather than talking.<\/li>\n\n\n\n<li><strong>b. AC interference<\/strong>: AC interference is caused by electrical signals from nearby devices or improperly grounded equipment. It typically appears as regular, sharp spikes on the ECG tracing, which is different from the erratic baseline caused by speech.<\/li>\n\n\n\n<li><strong>c. Interrupted baseline<\/strong>: This occurs when there is a disconnection or problem with one of the leads. It causes a flat, straight line on the ECG, which is not typically the result of the patient talking.<\/li>\n<\/ul>\n\n\n\n<p>The <strong>wandering baseline<\/strong> caused by talking can often be reduced by asking the patient to remain still and avoid speaking during the ECG. Ensuring proper electrode placement and reducing movement can help minimize this artifact and provide a clearer reading of the heart&#8217;s electrical activity.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/03\/image-468.png\" alt=\"\" class=\"wp-image-197388\"\/><\/figure>\n\n\n\n<p>Here is an illustration showing an ECG tracing with a wandering baseline artifact, which occurs when a patient talks during the ECG.
