Concerns About Short QT Interval: Seeking Guidance
I’m a 19-year-old male who has undergone two ECG tests recently. The first test indicated a QT/QTc duration of 0.24 seconds. I’ve been experiencing symptoms such as a feeling of heaviness, dizziness, and occasional fatigue, especially after activities like walking or dancing. At times, the fatigue has been intense enough that it feels as though I’m descending in an elevator. During some episodes of anxiety, I’ve noticed my blood pressure spike to around 140/80. Concerned about this, I monitored my blood pressure and found my heart rate was elevated—often exceeding 100 beats per minute while standing still. This prompted me to get an ECG, which revealed a short QT interval, leading to some anxiety on my part. To clarify, I conducted the measurements myself, so I’m seeking someone to confirm these findings. It’s worth noting that my previous ECGs had normal results. I also have a family history of cardiovascular issues, including: - My grandfather suffered from a heart attack and stroke. - My grandmother experienced a heart attack and has hypertension. - My mother has enlarged heart walls and hypertension. - My father has diabetes and has had a heart attack. On the medical front, my thyroid function is normal, and I have yet to complete any blood tests. I also deal with chronic conditions such as panic disorder, anxiety, depersonalization-derealization disorder, and vegetative dystonia. In my first ECG, recorded at 50 mm/s, my heart rate was between 110-120 bpm. Notably, the ECG featured handwritten instructions in Russian indicating when to inhale. The second ECG I underwent today was at a speed of 25 mm/s, with a heart rate of 120 bpm. Both tests indicated sinus tachycardia. Despite my efforts to remain calm during the procedures, I was unsuccessful. However, when I am at home, my heart rate typically stabilizes around 80, occasionally dropping to the 40s at night.

Your concerns about a short QT interval and the symptoms you're experiencing, such as dizziness, fatigue, and elevated heart rates, are understandable, especially given your family history of cardiovascular issues. Here’s a structured response to address your situation.
Main Points:
- You have a short QT interval on ECG, which can be a concern.
- Your symptoms of dizziness and fatigue, along with a family history of heart issues, warrant attention.
- It's crucial to monitor your symptoms and blood pressure, particularly during episodes of anxiety.
Explanation:
A short QT interval can be significant because it may increase the risk of certain arrhythmias (irregular heartbeats). Normal QT intervals generally range from 0.35 to 0.45 seconds, so a duration of 0.24 seconds is indeed shorter than the typical range. Your feelings of dizziness and fatigue can be related to several factors, including potential issues with your heart rate, anxiety, or even low blood pressure.
Given your family history and your symptoms, it’s important to consider both cardiovascular health and the management of your anxiety and panic disorders. Anxiety can cause both increased heart rate and elevated blood pressure, which may complicate your symptoms and experience.
Next Steps:
-
Track Your Symptoms: Keep a diary of your symptoms, noting when they occur, their intensity, and any triggering activities. Include instances of elevated heart rate and blood pressure readings.
-
Lifestyle Adjustments:
- Hydration: Ensure you are well-hydrated, as dehydration can sometimes lead to increased heart rate and dizziness.
- Stress Management Techniques: Practice relaxation strategies such as deep breathing, meditation, or gentle yoga. Managing anxiety can help stabilize heart rate and reduce symptoms.
- Physical Activity: Engage in low-intensity activities to help strengthen your heart without overexerting yourself. Gradually increase your activity level as tolerated.
-
Monitor Heart Rate and Blood Pressure: Keep checking your blood pressure and heart rate regularly at home, particularly after engaging in activities that typically cause symptoms.
-
Follow-Up Tests: Consider asking for a complete blood test, including electrolyte levels and thyroid function, to rule out other underlying conditions. A cardiologist might also recommend further tests like an echocardiogram or Holter monitor to better evaluate your heart function.
-
Discuss Findings: Share your ECG results, symptoms, and family history with a healthcare provider, ideally a cardiologist. They can interpret your results in the context of your overall health.
-
Consider Psychological Support: Since you have a history of anxious episodes, seeking support from a mental health professional can also be beneficial as it may help address both anxiety and its impact on your physical symptoms.
By prioritizing these steps, you can better understand your health, alleviate some anxiety, and take proactive measures for your well-being. Remember, you are not alone in this, and it’s good to seek further clarification with a healthcare professional.

Experiencing Clear Fluid from Ear with No Discomfort: Should I Wait for My Appointment?
I am a healthy 57-year-old female, weighing 120 pounds and standing 5 feet 5 inches tall. My daily medications include 100 mg of Losartan for effectively managed high blood pressure, 200 mg of Lyrica taken twice daily for post-herpetic neuralgia, 100 mg of Synthroid following treatment for thyroid cancer, and a combination hormone replacement therapy patch. Additionally, I take Zyrtec and Flonase every day to combat allergies. Since October, I have been dealing with persistent tinnitus in my right ear, accompanied by some pressure and a muffled sensation. Recently, I've noticed that when I speak, it feels akin to the sensation I experience when my ears clear during a flight after chewing gum—my voice sounds amplified in my head. I've scheduled an appointment with a physician's assistant in an ear, nose, and throat (ENT) office for the end of March due to my worries about the tinnitus and any potential hearing impairment. Yesterday, I noticed that my ear emitted a clear fluid. Thankfully, there was no associated pain. The fluid was somewhat thicker than water, completely odorless—unlike the unpleasant discharge I recall from my daughter's ear infections—and there was no sign of blood. Could this indicate a perforated eardrum? I suspect this might be the case, but can this occur without an underlying infection? Should I seek attention sooner than my appointment in March? I would prefer to avoid urgent care during flu season; however, if this situation is serious, I am prepared to take precautions and visit.
Understanding the Increased Pain in My Foot While Reclining
At 30 years old, I am nearing the five-week mark since undergoing surgery on my metatarsals. I've encountered a troubling issue: I can’t seem to find comfort when lying down, whether it’s with my foot raised or lying flat. My pain level escalates to a severe 10 out of 10, unless my foot is making contact with the floor or I dangle my leg off the side of the bed so that my toes touch the ground. Is this situation typical for someone in my circumstances? Are there any suggestions that might assist me in getting a better night's sleep?
Assessing My Health Concerns: How Anxious Should I Be?
I’m a 32-year-old woman, weighing 124 pounds and standing at 5 feet 6 inches tall. For over a year, I have been experiencing bright red rectal bleeding. Initially, I attributed this issue to hemorrhoids that developed during my pregnancy two years ago. The bleeding occurs with most of my bowel movements, sometimes happens without one, and on a few occasions, has been enough to stain the toilet bowl significantly. The color of the blood is typically darker than what I observe during a hemorrhoid flare-up. There is a notable family history of bowel cancer on both sides; one family member was diagnosed at age 45, and another at 60. In the past six months, I have encountered several episodes of severe abdominal pain—3 to 4 instances—intense enough to consider a trip to the emergency room. However, the pain usually subsides within about an hour. It’s unusual for me to experience such acute pain, given my high tolerance for discomfort; for example, I once played rugby shortly after dislocating and fracturing my finger. Recently, I mustered the courage to consult with my doctor, who recommended a FIT test, which returned a positive result (30.1). Additionally, I underwent a complete blood test, and aside from having low ferritin levels (7 µg/L), all other results were normal. I have since been referred for a colonoscopy on a two-week waiting list to rule out any possible bowel cancer. Given these circumstances, how concerned should I be? Thank you for your input.
Understanding Possible Seizure Triggers and Recurrence Risks
Health Background: I am a 21-year-old female, standing at 169 cm and weighing 65 kg. Over the past three years, I have been using oral contraceptives. As of this morning, I started taking 25 mcg of levothyroxine along with a weekly vitamin D supplement of 0.266 mg. Recently, I was diagnosed with hypothyroidism and found to have a vitamin D deficiency that I suspect has existed for the last three years. I do not consume alcohol or smoke, and I can confirm I am not pregnant. Two years ago, I experienced a mild concussion. I currently reside in Spain. A couple of months back, in mid-December, I blacked out twice. The second occurrence took place while I was at the doctor’s office after seeking urgent medical care for the initial incident. Following the second episode, I underwent a CT scan and an EKG, both of which returned normal results. Further tests, as directed by my physician, revealed a critical vitamin D deficiency and hypothyroidism; however, he expressed doubt that either of these conditions led to my loss of consciousness. I was then referred to a neurologist, and I am presently awaiting an appointment. Although the waiting period is lengthy, my doctor indicated that I should receive priority for scheduling, although the exact timeframe remains uncertain. The referral document summarized my events, labeling the second episode (which the physician witnessed) as a potential seizure devoid of tonic-clonic movements—a revelation that took me by surprise. After regaining consciousness, I felt extremely disoriented and terrified, struggling to process what was happening. I have no prior history of seizures, epilepsy, or any related conditions, and there is no known family history of these issues. If this indeed was a seizure, what might have triggered it? Additionally, what is the likelihood of experiencing another one? Since that time, I have not had any further incidents, but I have experienced moments where I felt a sense of impending doom, which I managed to overcome. I intend to wait for the neurologist's evaluation, but the uncertainty surrounding a possible neurological condition is quite distressing. Thank you for any insight you can provide!
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!
