Intraventricular Conduction Abnormalities in an Infant
A 12-month-old girl exhibited episodes of unresponsiveness along with atypical movements that raised concerns about possible seizures. Notably, her mother suffers from atrial tachycardia, which has been managed through an ablation procedure. One evening, while observing my daughter in her crib, we noticed she was behaving unusually. Upon closer inspection, we found her shaking and appearing dazed, a state that lasted approximately thirty minutes while we held her (she had shown similar signs for about half an hour prior in her crib). At the time, she didn't display any fever, but by the time we reached urgent care, a fever had developed. An ECG performed in the emergency room was reported as normal by the attending physician. However, six days later, we received a call advising us to come in for a follow-up ECG due to some concerning elements noted in her previous test; this indicated signs of sinus tachycardia accompanied by a shortened PR interval and nonspecific intraventricular conduction block. Upon undergoing a repeat ECG, the results appeared normal again, leaving the doctor uncertain about the necessity of the follow-up visit. Is it standard procedure for repeat ECGs to be conducted under these circumstances?

It's understandable to feel concerned about your daughter's episodes and the varying ECG results. Intraventricular conduction abnormalities can sometimes indicate underlying heart issues, so here's a structured overview of what you should know and do next.
Main Points:
- Intraventricular conduction abnormalities can be concerning, but they may not always indicate serious issues, especially if follow-up ECGs return to normal.
- Monitoring your child's symptoms and heart patterns is essential for further clarity.
Explanation:
Your daughter's behavior—episodes of unresponsiveness and atypical shaking—raises valid concerns, especially in light of her family history with cardiac issues. Initially, the ECG showed signs that prompted the doctor to recommend a follow-up due to potential intraventricular conduction issues. Sinus tachycardia and a shortened PR interval can be benign in some cases, particularly in infants, where their heart rhythms and conduction patterns can vary as they grow.
Next Steps:
-
Monitor Symptoms: Keep a diary of your daughter's episodes. Note the duration, frequency, any preceding factors (like fever or fatigue), and how she feels afterwards. This will help you and her healthcare providers assess her condition.
-
Follow-Up Visits: Schedule the follow-up visits your healthcare provider suggests. They may recommend further testing or monitoring based on her ongoing symptoms and heart function.
-
Stay Informed: Educate yourself about signs to watch for, like sudden changes in consciousness, prolonged episodes, or any other concerning symptoms. This knowledge will help you feel more empowered.
-
Seek Clarification: If there’s uncertainty regarding the need for repeat ECGs, consider discussing this with your child’s doctor. Understanding the rationale can provide peace of mind and reassure you about her care plan.
Feeling uncertain about your child's health is completely natural, and you're taking the right steps by seeking information and monitoring her closely. If any new symptoms arise or if you have ongoing concerns, don’t hesitate to reach out to your healthcare provider promptly.

Battling Chronic Nausea and Vomiting for Over Two Years
For the past two years, I (age 26, female) have been enduring an incredibly challenging health situation. I experience intense nausea daily and find myself vomiting numerous times, with almost nothing providing relief. To provide some background, I’m from West Texas and I currently weigh around 190 pounds, standing at 5’7”. Initially, my weight was about 211 pounds when these symptoms began, and it fluctuates frequently between 190 and 225 pounds. I engage in vaping and consume THC. Previously diagnosed with hypothyroidism, my condition seemingly resolved, according to my healthcare providers. Additionally, I have polycystic ovarian syndrome (PCOS). I have consistently faced irregular bowel movements, with stools that are loose and sometimes appear to have mucus. Compounding my struggles, I've also suffered from migraines. I have had an IUD for over five years, experiencing two insertions of the Kyleena device. In December 2022, my battle with health took a severe turn when I was diagnosed with stage 4 Hodgkin’s Lymphoma, requiring chemotherapy treatment, specifically AVBD (Apologies for not recalling the exact medication names). By July 2023, I had fortunately achieved remission. However, after reaching remission, my vomiting worsened, transforming from primarily white foam to a mixture of 80% bile, any food I attempt to consume, and still white foam. This intense vomiting, accompanied by significant pain in my upper back, escalated to more than eight episodes daily by November 2023. At that time, THC seemed to be the only avenue for me to retain any food. During this tumultuous period, I consulted various doctors who, after confirming I wasn’t pregnant, attributed my symptoms to Cannabinoid Hyperemesis Syndrome (CHS). Immediately, I ceased THC consumption for over six months, yet the vomiting continued unabated. Each time, doctors would prescribe ondansetron, regardless of my claims that it provided no relief. I experimented with various diets recommended by medical professionals, but there were no improvements in my condition. Eventually, I obtained a referral to a gastroenterologist who intended to perform an endoscopy. However, the procedure was prohibitively expensive even with insurance, and thus was never conducted. This doctor also ordered blood tests to rule out several gastrointestinal disorders, such as Crohn's disease, Irritable Bowel Syndrome (IBS), and gluten sensitivity, but all results came back normal. Afterward, I had another appointment with a different gastroenterologist, but the doctor failed to meet with me. Instead, a nurse informed me that the doctor had merely recommended promethazine without conducting any tests or scheduling further visits. When I mentioned the possibility of gallbladder issues, the doctor laughed dismissively at my suggestion. Discussing my situation with my oncologist, he suggested that my heightened sensitivity to food odors stemmed from my chemotherapy experiences while I was working in fast food. While food smells indeed affect me, I'm primarily triggered by medical scents such as rubbing alcohol and cleaning agents. This ongoing ordeal has been overwhelmingly distressing. I now experience episodes of vomiting accompanied by bright red blood, presumably due to a throat tear. When I first encountered this troubling symptom, I consulted a doctor who appeared unfazed and prescribed a promethazine suppository, which does help but makes me extremely drowsy. My nausea persists nearly around the clock, often feeling as if there’s a heaviness in the upper part of my abdomen. I frequent urgent care facilities when my symptoms intensify, only to be met with minimal assistance since this is a chronic issue. Currently, I lack a primary care physician. Whenever I sought one, I encountered skepticism regarding my condition, with some healthcare professionals implying that I was exaggerating my symptoms. Though many physicians who do take my situation seriously seem baffled, I've lost count of the diverse medical experts I've consulted about these ongoing issues. If anyone has insight or suggestions, I would genuinely appreciate it. I can share my latest bloodwork results if that would be helpful—just let me know!
Understanding Tuberculosis Exposure Risk
A 26-year-old male, who neither drinks alcohol nor smokes, seeks to understand the implications of exposure to tuberculosis (TB). As an anesthesia technician, I became concerned after I encountered a TB-positive patient about a month ago. I had to enter the patient’s room several times to perform blood gas tests. On my first entry, I mistakenly wore my N95 mask incorrectly due to the hectic nature of attending to multiple rooms. From my research, it appears that TB is quite transmissible; direct exposure can pose a serious risk of infection. Transmission usually requires prolonged contact with an infected individual, particularly in a close or face-to-face setting. In this case, the patient was lying face down and appeared to be sleeping when I entered. I have already undergone testing for TB, but I am eager to deepen my understanding of the risks involved in these situations.
24M | Unexplained Fainting Incident
**Note:** I previously shared this story, but it was inexplicably removed. I’m a 24-year-old male without any medical diagnosis or prescription medications. While I do consume alcohol occasionally, I hadn’t been drinking before this happened. Around 3 a.m., I got up from bed to use the restroom. As soon as I began to urinate, I suddenly felt a wave of dizziness. The next moment I was aware of was regaining consciousness in the bathtub, startled awake by the sensation of something dripping on me—only to discover it was my own blood. This was my first experience with fainting. When I came to, confusion set in. I was disoriented and couldn’t comprehend why I was being dripped on while in what I thought was my “bed.” Strangely, I also imagined that I was lying on a collection of marbles (which I actually don’t own)—this turned out to be the shattered glass of my shower door lying around me. I’m uncertain whether I lost consciousness first and then fell, or if the fall caused my brief blackout. It took me a few moments to understand why I was in the bathroom at all. I’m not sure how long I was out; I only remember it was around 3 in the morning when I initially got up, and about the same time when I regained consciousness. I dialed 911, and the ambulance arrived promptly. They checked my vitals, performed an EKG and measured my blood sugar, finding nothing unusual. At the emergency room, they repeated the vital checks, conducted a CT scan, drew blood, and took x-rays—yet still no abnormalities were detected. I had several cuts on my face and left arm (curiously, this is the arm that would have been turned away from the door), along with bruising around my ribs. Since the incident, I’ve been suffering from headaches and pain in my ribs. I received stitches on both my face and arm. The nurse suggested I could have stronger pain relief, but I opted for just Toradol. They eventually discharged me, stating, "We’re unsure what caused this, but return if it happens again." What might have triggered such an incident? How can I safeguard against it reoccurring if they remain uncertain about the cause?
Swelling Beneath My Chin Near the Jawline
18-Year-Old Male: I'm reaching out to any medical professionals who might provide insights into my situation. I've been using marijuana since I was 14, but now, at 17, I'm making an effort to stop and have been clean for 18 days. Recently, I've discovered an unusual swelling located just beneath my chin, behind my jaw. It causes some discomfort when I move, yet it doesn’t feel painful continuously. I'm somewhat anxious that this could be indicative of a more serious issue, especially considering it's positioned near my chin's lymph nodes. Any advice or information would be greatly appreciated as it might help alleviate my worry.
Challenges with Appetite and Discomfort While Eating — Difficulty in Gaining Weight
As an 18-year-old male, I find that I become satisfied after consuming rather minimal amounts of food. This situation presents a considerable challenge, particularly since I only need to have a standard breakfast, lunch, or dinner to feel completely satiated for the remainder of the day. My goal of increasing my weight has made this issue even more complicated. When I limit myself to one meal per day, I often face weight loss or an uncomfortable sensation of fullness that leaves me feeling sluggish. Opting for two meals makes me feel excessively bloated, distracting me from my daily responsibilities. Moreover, I suffer from an unusual issue with my throat, where almost any food I consume causes discomfort, as detailed in the list below. I have contemplated focusing on having just lunch while continuing my weightlifting regimen to maintain my current weight and gradually build muscle. What advice could you offer? Could there be an underlying cause for these symptoms? Lastly, would it be wise for me to consult a healthcare professional? Foods That Cause Discomfort: Bread, flour, pizza, fruits, sugary or starchy items, seed oils, chips, and essentially everything else. Foods That Are Tolerable: Rice, salads, chicken, fish, and vegetables. Overall Symptoms Include: * Quick satiety after normal meals * Challenges in gaining weight * Bloated and lethargic sensations when consuming more than one meal * Persistent throat sensitivity to a wide variety of foods
