Pacemaker, Neck Pain, and a Request for Electroacupuncture
A 76-year-old woman with a dual-chamber pacemaker implanted two years ago for sick sinus syndrome presents with neck and upper back pain after a minor motor vehicle collision. Pain is 5/10 and limits rotation. She read that electroacupuncture is effective for neck pain and asks for it. Her medications include metoprolol; she takes no anticoagulant. Her pulse is 62 and irregular at times, blood pressure 128/74. The pacemaker pocket is visible below the left clavicle and is not tender. The clinic's electroacupuncture device has a manufacturer warning to avoid use in patients with implanted electronic devices. She has not had device interrogation in 14 months. She denies palpitations, syncope, or chest pain today. She wants the strongest setting that is safe.
1. Is electroacupuncture appropriate? Explain the reasoning.

No. Electroacupuncture passes current through needles, and that current can be conducted to the chest and interfere with pacemaker sensing or pacing. The result could be inhibition of pacing, inappropriate rapid pacing, or device malfunction, and the risk is not reliably eliminated by choosing distant points or low settings. The manufacturer warning is consistent with that concern. Because she has a pacemaker and has not had recent interrogation, I would not use electroacupuncture or TENS anywhere on her body. I would explain that the request is understandable but that the device makes electrical stimulation inappropriate in this setting. If she wants electrical stimulation specifically, she should discuss it with her cardiologist or device clinic; I would not experiment with settings.
2. What manual acupuncture precautions and alternatives would you use?
Read the worked answer
I would use gentle manual acupuncture with fine needles, avoiding the pacemaker pocket and the area directly over the device and leads. I would favor distal and local points away from the chest, such as SI3, GB34, LI4, and safe cervical and upper trapezius points, with shallow needling and no strong deqi. I would keep the session conservative because vasovagal reactions can be more concerning in an older patient with a cardiac device. I would monitor pulse and blood pressure before, during, and after treatment and ask her to report palpitations, dizziness, or chest discomfort immediately. Alternatives include acupressure, gentle mobilization, and referral for manual therapy. The reasoning is that manual needling does not introduce electrical current, but the device still requires avoidance of the pocket and careful monitoring.
3. What would you do if she develops palpitations and dizziness during needling?
Read the worked answer
I would stop stimulation, remove all needles, and place her supine with legs elevated if her blood pressure is low. I would check pulse, blood pressure, respiratory rate, and level of consciousness, and ask about chest pain, shortness of breath, and syncope. Because she has a pacemaker and new palpitations, I would not assume a simple vasovagal reaction. If symptoms persist, worsen, or are accompanied by chest pain, dyspnea, or altered consciousness, I would call emergency services and notify her cardiologist or device clinic. I would document the onset, points used, vital signs, and actions taken. The reasoning is that device dysfunction and arrhythmia are time-sensitive possibilities, and observation alone is not sufficient when a patient with an implanted cardiac device develops new cardiac symptoms.
