Understanding Diffuse T Wave Changes
Subject: 19 years old, Female, 5’5", weight 135 lbs. Currently, I’m not taking any medications, although I previously used Seroquel in doses ranging from 25 to 100 mg to assist with sleep. Last November, I underwent an ECG, which revealed diffuse T wave inversions across all leads, excluding leads I, aVR, and V1. I have had an echocardiogram that confirmed there are no structural issues with my heart. Additionally, I wore a Holter monitor for 72 hours that recorded a sinus rhythm with a mean heart rate of 80 bpm, showing nonspecific T wave alterations throughout the monitoring period. A stress test was also administered, which indicated no ischemic changes during exertion. Over the past year, I have had four ECGs, all yielding similar results, the latest being conducted just last week. I am aware that T wave alterations can sometimes be benign variations. Notably, I had an ECG back in 2021 that showed no ST segment changes. At present, I do not experience chest pain or shortness of breath; however, I occasionally feel palpitations—about one to three times every five days, each lasting less than a second. I have been advised to check my electrolyte levels; however, my cardiologist remains skeptical that this could be related to any electrolyte imbalance. He has scheduled a follow-up echo and ECG for a year from now, explaining that these tests may provide insight into potential structural changes that could indicate future cardiomyopathy. I do not have a family history of this condition and I previously vaped, but I stopped approximately ten months ago. If anyone has advice on further steps or insights into my situation, I welcome your input!

It sounds like you’ve been closely monitored for your heart health, and it's understandable to have questions about your ECG results and any associated symptoms. Your findings reveal persistently inverted T waves, yet numerous tests have ruled out significant structural heart issues. Here’s a summary and guidance based on the information you provided:
Main Points:
- Diffuse T Wave Inversion: While often benign, persistent T wave inversions can be a cause for investigation.
- Cardiac Evaluations: You've had multiple tests that suggest no serious underlying heart conditions.
- Symptoms: Palpitations are common and may not be related to the T wave findings.
Explanation:
- T Wave Changes: Diffuse T wave inversions can occur due to various reasons, like normal anatomical variations, stress, electrolyte imbalances, or even effects from previous medications like Seroquel. Since you’ve had comprehensive tests (echo, Holter monitor, stress test) without identifying any structural heart problems, it is reassuring.
- Palpitations: Occasional palpitations lasting a second or less are frequently benign, particularly if you're not experiencing any other concerning symptoms like dizziness or chest pain.
Next Steps:
-
Monitor Symptoms: Continue to keep a diary of your palpitations. Note their frequency, duration, and any potential triggers (like stress or caffeine). This can help identify patterns and inform future discussions with your cardiologist.
-
Electrolyte Levels: Follow through with checking your electrolyte levels as suggested. Maintaining a balanced diet rich in potassium, magnesium, and calcium can be beneficial.
-
Lifestyle Modifications: Ensure you maintain a healthy lifestyle — stay hydrated, eat well, manage stress through techniques like mindfulness or yoga, and avoid stimulants (caffeine, nicotine) that can aggravate palpitations.
-
Regular Follow-ups: Follow your cardiologist's plan regarding future ECGs and echo tests. If at any point your symptoms change (e.g., increased frequency of palpitations, new symptoms), make sure to communicate these with your doctor.
-
Stay Informed: Continue to educate yourself about your condition and engage actively in discussions with your healthcare providers.
Reassurance:
It’s excellent that you are engaged and proactive about your heart health. Many individuals with similar ECG findings go on to lead healthy lives without significant issues. If you have any further concerns, please reach out to your healthcare provider. You're taking the right steps by monitoring your health and seeking information!

Is This a Tick Bite?
My 2-year-old child has a normal BMI and isn't on any medication. I need some help identifying a potential issue. Yesterday, we observed what we thought was a mosquito bite behind my son's ear, but today it appears quite different (please refer to the photo in the comments). I'm worried it might actually be a tick bite. I’m not sure what else could create a bullseye pattern like this one.
Should I Return to the Emergency Room?
A 25-year-old female, measuring a little over 5 feet 6 inches tall and weighing 117 pounds, visited the emergency room yesterday due to significant light-headedness and shortness of breath. She believed these symptoms were linked to her menstrual cycle, as she suffers from severe premenstrual dysphoric disorder (PMDD). The hospital conducted a comprehensive evaluation: electrolyte levels were within the normal range, blood count showed no abnormalities, the electrocardiogram was normal, troponin levels were satisfactory, d-dimer was negative, and there was no sign of anemia. Additionally, her partial thromboplastin time (PTT) and B-type natriuretic peptide (BNP) levels were normal, and vital signs were stable throughout the examination. The medical staff administered fluids and concluded that no immediate dangers were present, suggesting that her symptoms likely did not stem from her menstrual cycle. They recommended a follow-up with her primary care physician and advised her to return if her condition worsened. Today, her menstruation is noticeably lighter, but she continues to experience persistent light-headedness. This morning, she felt on the brink of fainting simply while using the restroom or bending down to retrieve an item and also experienced significant nausea. After consuming some food and an electrolyte-rich beverage, she feels slightly improved, yet something still feels off. With a primary care appointment scheduled for tomorrow, she is left wondering whether to visit urgent care or the ER again.
Concerns Regarding Gallbladder Issues
At 17 years old, I’ve been unwell for the past 16 days, initially starting with a severe cold. However, a week ago, I began experiencing vomiting and am now struggling to retain even water. Ultimately, I visited the doctor today (not something I wanted to do, but my mom insisted!). After conducting several tests, they indicated a strong suspicion it involves my gallbladder, but a CT scan is necessary for definitive confirmation. Just as I was preparing to head to work, the hospital called about the CT scan. When I requested to postpone it until the next day, they firmly insisted that it must be done immediately – my job could wait. Upon receiving the results, the radiologist didn’t sufficiently address my gallbladder in the report, leaving my doctor frustrated. She decided we’ll proceed with an ultrasound focused specifically on my gallbladder tomorrow, as she feels very confident that this is the issue. Although I know I should be patient for the outcomes, my anxiety is escalating, and I find it hard to function with all this worry weighing on my mind. Is a malfunctioning gallbladder a serious concern? The doctor mentioned my blood work revealed quite high levels pertaining to it. Is this a condition that can be treated simply with medication? My mom underwent gallbladder removal years back and has shared how difficult that was, which only adds to my panic. I am left wondering whether surgery is inevitable or if I might just be prescribed something. To summarize, I’m very ill, unable to keep water down, severely dehydrated, and my doctor has indicated a high likelihood of gallbladder involvement. Now, I'm left anxiously awaiting the results of my ultrasound.
