Seeking Guidance on Post-ICD Shock and Seizure Episodes
Greetings, everyone. I am reaching out on behalf of a relative and would greatly value any shared experiences, insights, or recommendations. --- **Patient Details:** - **Age:** 55 years - **Sex:** Male - **Medical History:** Sudden cardiac arrest, first occurrence - **Ejection Fraction (EF):** Currently at 35% - **ICD Status:** Implantable Cardioverter Defibrillator has been implanted - **Angiography:** Conducted 4 days post-cardiac arrest due to fluctuating blood pressure - **Timeframe:** Hospital admission was 18 hours following the cardiac event --- **Incident Overview:** The initial event was a complete cardiac arrest that took place at home. The patient was semi-conscious and was transported to a medical facility after a delay of 18 hours. Due to blood pressure instability, angiography could not be performed immediately and was conducted four days later. An ICD was placed, and he appeared to be making a good recovery initially. --- **Current Challenges (Post-ICD):** Approximately 50 hours following the ICD installation, he experienced an unusual episode that resembled a seizure. During this event, his entire body became rigid, his eyes rolled back, and he was unresponsive for several seconds. An assessment of the ICD logs indicated that it had switched to pacemaker mode, without delivering any shocks. After being gently shaken, he quickly regained awareness and returned to his usual state. Notably, similar episodes of brief unresponsiveness had occurred prior to the ICD placement as well.

Experiencing post-ICD episodes similar to seizures can be concerning, especially after a recent cardiac event. The key points here revolve around understanding the potential causes of these episodes, closely monitoring the patient's condition, and taking specific actions to ensure safety and improve symptom management.
Explanation:
The episodes your relative is experiencing could be related to a combination of factors, including the effects of the ICD, neurological responses, or underlying cardiac issues. Since he has a history of sudden cardiac arrest and has recently undergone significant procedures, it's essential to carefully observe and report these occurrences to his healthcare team.
Next Steps:
-
Monitor Symptoms: Keep a detailed log of the episodes, noting the date, duration, symptoms (rigidity, eye rolling, unresponsiveness), and any potential triggers (e.g., stress, fatigue, medications). This will help healthcare providers understand the pattern and frequency.
-
Safety Precautions: Ensure a safe environment for the patient. If he experiences any further episodes, create a safe space for him to fall without injury. Consider having someone nearby during activities that may provoke a seizure-like response.
-
Hydration and Diet: Encourage the patient to stay well-hydrated and maintain a balanced diet. Low blood sugar or dehydration could contribute to episodes of unresponsiveness.
-
Medication Review: If the patient is on any new medications or has changes in dosages, review these with the healthcare team, as they may affect how he responds neurologically.
-
Follow-Up Appointment: Write down key observations and concerns to bring to the next medical appointment, particularly the experience of brief unresponsiveness and how the ICD has been functioning.
-
Emergency Plan: Develop an action plan for when these episodes occur. If he becomes unresponsive again or experiences additional unusual symptoms (like increased heart rate or chest pain), knowing when to seek immediate medical care is crucial.
It’s important to approach this situation with care and keep communication lines open with healthcare providers for any changes or new symptoms. Most importantly, reassure your relative that monitoring and taking these steps can help manage his health effectively.

Persistent Pain in Right Shoulder and Arm After Lifting
Hello, everyone! I’m a 23-year-old male and have been engaged in weightlifting for several years now. Recently, I’ve been struggling with ongoing discomfort in my right shoulder and arm, which I haven’t been able to accurately identify. The pain manifests during particular movements, especially with lateral raises or when my arm is raised to shoulder level while rotating my wrist. Certain pressing and pulling activities can also provoke this discomfort. Rather than feeling sharp, it’s a deep, nagging sensation that sometimes seems localized in the front area of the shoulder or at the biceps tendon, and at other times it feels more like it’s situated between the shoulder and upper arm. Fortunately, there’s no numbness or tingling involved. This issue began while I was working out. I decided to take a break for around two months, but when I returned, the pain persisted. After consulting a physician, I was diagnosed with bicipital tendinitis. Since then, I’ve reduced my upper-body workouts, completely steering clear of shoulder exercises and heavy lifting, and have begun a gentle rehabilitation regimen focusing on external rotations, pendulum movements, and scapular exercises. Despite adhering to this routine for about a week, I haven’t experienced any noticeable improvement. Is it typical for this type of tendon injury to require an extended period for recovery? At what point should I consider diagnostic imaging, such as an ultrasound or MRI? Additionally, are there frequent rehabilitation errors that might impede the healing process? I appreciate your insights in advance!
Understanding EEG Results for My 22-Month-Old Son: Insights Needed
Could someone help clarify this for me? My son, who is just 22 months old, hasn’t started walking yet, becomes tired easily, and has been experiencing behavioral outbursts. He had a febrile seizure in February 2025, followed by another unexplained seizure in April 2025, which led us to consult a neurologist. Since he was 3 months old, he has been receiving therapy from a physical therapist for torticollis. At birth, he spent five days in the NICU due to issues with meconium aspiration. A recent MRI showed normal results, and he also had a follow-up EEG after one conducted in July 2025. The results from this recent EEG were abnormal for a pediatric patient in awake, drowsy, and sleeping states. Notably, there were brief episodes of left frontotemporal delta slowing, which occurred mainly when he was awake and drowsy. There were no signs of epileptiform activity detected. In contrast, the EEG performed back on July 3, 2025, was deemed normal for both awake and drowsy states, again with no evidence of epileptiform irregularities, although it did not capture any sleep data. This examination was prompted by the child's existing history of febrile seizures. Importantly, he is not currently on any anti-seizure medications. The EEG procedure used standard electrode placements per the 10-20 system, conducted a single-lead EKG, and included continuous video monitoring. During the analysis, the background activity was symmetric, indicating some anterior-posterior (AP) organization, with a dominant rhythm of 50-80 microvolts at 7 Hz. His drowsy state was marked by a reduced amount of eye blink activity, less breathing motion interference, and a generalized slowing in theta/delta frequencies. Stage II sleep exhibited spindles and vertex waves patterns. Additionally, there were intermittent bursts of 250-300 microvolts in the left frontotemporal region with semi-rhythmic activity of 2-4 Hz, mostly observed during wakefulness and drowsiness. No definitive epileptiform discharge was noted. Photic stimulation during the test did not elicit a strong response, and hyperventilation was not conducted during this session.
Understanding Atrial Fibrillation and Thyroid Issues: Variability in Cardioversion Decisions
Hello everyone, I’m reaching out for guidance regarding my mother’s current health situation, and I’d greatly appreciate any shared experiences or thoughts. **My mother's background:** - **Age**: 55 years - **Weight**: Recently dropped to 116 kg from 118 kg in just two days, likely due to diuretics. - **Health history**: Previously an underactive thyroid, undiagnosed and untreated, now presenting as overactive. - **Medications**: Currently taking thyroid medication and a beta-blocker (Rapiblock). **Current health status:** My mother has been hospitalized since Tuesday, experiencing **atrial fibrillation with heart rates exceeding 200** beats per minute due to her thyroid's hyperactivity. - The plan for cardioversion was initially settled on Tuesday. However, the following day, the medical team advised postponing it until her thyroid levels could be stabilized, believing that her heart rate would return to normal once her thyroid condition was managed. - Her **obesity** precludes her from undergoing a transthoracic echocardiogram, and due to her thyroid concerns, she cannot handle contrast dye (this has been a consistent issue for over four years). Therefore, the only feasible option was a **transesophageal echocardiogram (TEE)**, which has yet to be performed. - She has been prescribed various medications including beta-blockers and thyroid treatments in the past. - On Friday, a doctor proposed proceeding with cardioversion; however, the attending senior physician objected. - Today (Saturday), another clinician has expressed a desire to move forward with cardioversion, having initiated a new medication, as the senior physician is unavailable. - **Communication has been unclear**, as we were notified of developments by a nurse rather than the physician in charge, causing confusion and anxiety. - Currently, only a **chest X-ray** is scheduled, and the TEE remains unaddressed. **My inquiries are as follows:** 1. Is it common for medical professionals to have varying opinions and frequently revise medication or treatment plans like cardioversion? 2. Is it safe to conduct cardioversion in the absence of a TEE? I presumed that this was a standard procedure to exclude the presence of blood clots. 3. Is it usual practice to have only a chest X-ray prior to moving ahead with cardioversion? 4. How typical is it for patients or their families to not be directly informed about treatment changes and learn about them through nursing staff instead? I recognize that this cannot substitute for professional medical advice. I’m simply trying to discern whether these circumstances are typical or if we should express our concerns more assertively with the healthcare facility. Thank you for your insights!
28-Year-Old Male Experiencing Scalp Sensations Post-Amitriptyline Treatment
I am a 28-year-old man in generally good health, without any cardiac concerns. Approximately a month ago, I encountered intense pain localized to one side of my head, which was unresponsive to paracetamol. However, a single dose of a migraine treatment provided substantial relief. Following that, I began a regimen of amitriptyline, starting at a nightly dose of 10 to 25 mg. While my head pain has diminished significantly—by about 90 to 95%—I now experience occasional uncomfortable sensations on my scalp. These feelings include pins and needles, a cooling sensation, and some crawling feelings near my hairline and ears. There are fleeting moments where I feel brief throbs lasting a second, but I do not have any persistent headaches. To clarify, I do not experience any of the following: - Nausea - Weakness in my limbs - Numbness - Changes in my vision - Coordination difficulties - Seizures The symptoms I have are transient, shifting around and often intensifying when I become conscious of them or as the day progresses. I would like to know: Is it common to experience these sensations during the recovery stage following episodes of neuralgia or migraine-like discomfort? Additionally, could the amitriptyline potentially be causing these temporary paresthetic sensations? I am seeking some reassurance or advice on what is typically observed during this healing process. Thank you.
Concerns About My Toes
Age: 30, Female Currently, I am on the lookout for a reputable podiatrist in my vicinity. However, I've encountered a perplexing issue with my foot. Just last night, I noticed a growth on the side of my toe, something entirely new to me. I maintain a nutritious diet and have a demanding job that requires me to be on my feet quite often. My footwear includes brands such as Brooks Ghost Runners, Hoka Bondi 9’s, and Nike Motiva’s, and I don’t opt for restrictive socks. I also apply Vick’s Vaporub to my feet, a practice handed down from my family, and stick with simple, non-fragrant lotions like Vanicream and CeraVe SA Cream for my skin. In addition, I am curious about the my big toenail's change in color. What might be the underlying reasons for this? Also, I have these persistent dark spots on my toes that I've struggled with since my days on the runway. Despite my efforts, nothing has succeeded in lightening or diminishing their appearance. I'm just looking to determine if there might have been a factor from the past that could have contributed to these issues. I’m not sure what else to include, but I’m open to answering any questions you might have. Thank you for your attention! Best wishes from a worried soul!
