The Combative, Orthopneic Patient with a 'Stat' Order
You are called to the emergency department for a "stat 12-lead" on a 74-year-old woman with chest pain. Her chart lists dementia and Parkinson disease. She is calling out, picking at her telemetry leads, and cannot lie flat because of orthopnea. Vitals: HR 112 and irregular, BP 162/94, RR 24, SpO2 91% on room air. She has an IV in the left antecubital fossa, and her daughter is at the bedside. The stretcher is in semi-Fowler's, the room is cool, and her hands are visibly trembling. Two other patients are waiting, and the nurse says, "Just get the strip, we need it now."
1. What should you do in the first minute or two, before placing a single electrode - and what should you not do?

Work through the constraints rather than the order urgency alone.
Do: introduce yourself to the patient and the daughter; explain in short, calm sentences what you are about to do and that it will not hurt. Warm your hands and the electrodes - a cold room plus cold hands worsens both tremor and agitation. Recruit the daughter to help orient and settle her. Keep the head of the bed elevated; do not force her flat for a "better" tracing, because orthopnea means supine positioning will worsen her breathing and her restlessness.
Do not: physically restrain her, raise your voice, or strip her telemetry to "start clean" without coordinating with the nurse monitoring it. Do not let the nurse's urgency push you into a rushed, artifact-filled strip - a non-diagnostic tracing costs more time than 60 seconds of rapport.
If she remains unsafe to approach or is decompensating, stop and get the assigned nurse or provider; that is an escalation, not a failure.
2. Her tremor is producing somatic artifact on the limb leads. Give two or three specific interventions that will produce a diagnostic tracing, and state what must be documented.

Somatic tremor is a patient-source artifact; filtering alone will not fix it and can distort ST segments.
- Support the limbs. Rest both forearms on a pillow with the palms down and the hands not touching the abdomen or each other - muscle tension and skin-to-skin contact both add noise.
- Move the electrodes proximally if needed. Placing arm leads on the upper arms/shoulders and leg leads on the hips reduces the lever arm of the tremor. This is an accepted modification, but it changes morphology and amplitude, so it must be documented.
- Time the acquisition. Ask her to relax, briefly hold still, and capture during the quietest window; repeat acquisitions rather than accepting one noisy strip.
Document: that limb leads were relocated and where, that artifact was present, and which tracing was affected. A reader who does not know the leads were moved may misread axis or amplitude. Use the artifact filter sparingly and note it if used.
3. SpO2 is 91% and she is orthopneic. How does that change your positioning and your decision about stopping to get help?
Read the worked answer
Oxygenation outranks tracing technique. Keep her in semi-Fowler's or higher, let her use her own positioning, and do not ask her to lie flat at any point - a 12-lead can be obtained with the head of the bed up; you simply document the position because it can shift the electrical axis and precordial lead positions.
Re-check the SpO2 reading itself: is the probe on a cold, poorly perfused finger? A reliable 91% with orthopnea and chest pain is a red flag, not a number to chart and forget.
Set a stop rule for yourself. If she becomes more dyspneic, her mental status worsens, or she cannot tolerate the leads at all, stop, stay with her, and get the nurse or provider immediately - do not finish the strip first. Escalating a deteriorating patient is always the correct call; the physician can be told "tracing in progress, patient decompensating" and will act on that information faster than on a perfect but late EKG.
