Could It Be Sinus Tachycardia or Another Condition?
A 38-year-old female, standing at 5 feet 2 inches tall and weighing 101 pounds, has submitted an ECG for review. She has been experiencing a range of symptoms that encompass feelings of weakness, difficulty in breathing, discomfort in the chest, lightheadedness, and excessive sweating, all of which intensified as her heart rate increased. These issues persisted over several weeks, with her resting heart rate fluctuating between the 90s and 120s, and at times reaching sudden spikes of up to 180 beats per minute, particularly during the night. She has recently commenced treatment with metoprolol tartrate, which appears to be providing some relief.

It sounds like you're experiencing significant symptoms that can be concerning, particularly with your elevated heart rate and associated feelings of weakness and lightheadedness. Here’s a breakdown of your situation and some suggested next steps.
Key Points:
- Symptoms Overview: Your symptoms—chest discomfort, lightheadedness, difficulty breathing, excessive sweating, and a fast heart rate—can be associated with various conditions, including sinus tachycardia, anxiety, or more serious heart issues.
- Current Management: You have started on metoprolol tartrate, a medication that can help to control heart rate and may be beneficial in your case. It's good that you are already exploring treatment.
Explanation:
- Sinus Tachycardia: This occurs when the heart beats faster than normal (over 100 beats per minute) but follows a normal rhythm. Factors can include stress, anxiety, dehydration, or underlying medical conditions. Your symptoms, especially the spikes in heart rate, are concerning and warrant further evaluation.
- Underlying Causes: It’s crucial to identify what might be causing your elevated heart rate and other symptoms. Possible causes range from anxiety to cardiac issues or even hormonal imbalances.
Prioritized Next Steps:
-
Monitor Your Symptoms: Keep a detailed log of your symptoms, noting when they occur and any accompanying factors (like activity level, stress, etc.). This information can be very valuable for understanding your condition and guiding treatment.
-
Health Monitoring: Use a heart rate monitor to track your resting heart rate and how it responds to activity. Take note of any triggers for heart rate spikes.
-
Lifestyle Modifications:
- Stay hydrated: Dehydration can lead to an increased heart rate.
- Manage stress: Practice relaxation techniques such as deep breathing, yoga, or meditation to help regulate your heart rate.
- Limit caffeine and alcohol intake, as these can contribute to higher heart rates.
-
Follow Up on Medication: Keep in close contact with your healthcare provider regarding how you’re responding to the metoprolol. If your symptoms persist or worsen, they may need to adjust your dosage or explore other treatment options.
-
Emergency Symptoms: Be vigilant for any severe symptoms such as extreme shortness of breath, chest pain, or fainting spells. If these occur, seek immediate medical attention.
In summary, documenting your symptoms and making deliberate lifestyle adjustments can significantly help you manage your condition. You’re taking a good step by being proactive about treatment, and it’s important to stay in touch with your healthcare provider for ongoing management. Please let me know if you would like more specific guidance on any of these steps or have additional questions.

Elevated Heart Rate and Trembling Post Steam Bath
I recently had an experience that raised some concerns about my heart health. Despite not having any previously diagnosed heart conditions, I sometimes grapple with anxiety related to my heart. A recent medical check-up and blood work came back normal, which brought some relief. After a swimming session, I spent approximately 25 to 30 minutes unwinding in a steam room. However, upon exiting and moving to the shower, I noticed a dramatic spike in my heart rate, jumping from around 100 to 170 beats per minute as indicated by my smartwatch. This sudden elevation in heart rate left me feeling quite shaky. Fortunately, I was able to sit down, focus on calming myself, and avoided any fainting spells. In a short period of about three minutes, my heart rate decreased from the 160s back to 100. I frequently use the steam room without experiencing such a reaction previously. I can’t help but wonder if perhaps I didn’t hydrate adequately, consumed too much caffeine, or stayed in the steam room longer than usual. Could this episode indicate a more serious underlying issue, or was it just an isolated occurrence?
Unusual Tongue Condition
Last weekend, I participated in a three-day sleepover with my younger cousin, who seems to have a habit of coughing openly. Upon returning home, I began to feel unwell; I woke up with a pounding headache and a painful throat. By the final day of the sleepover, my discomfort intensified. I noticed a rash spreading across my face, and my throat was incredibly sore, similar to the experience of having stage 2 sunburn (an ordeal I went through last year) but without the blistering. Eating and drinking became increasingly painful, and even resting caused discomfort. Though the rash eventually faded, I was left with a peculiar appearance on my tongue. Frustratingly, my parents refuse to seek medical attention, dismissing my concerns as typical hypochondria. I find myself wondering about the strange changes happening with my tongue and whether I should urge them for a doctor’s visit.
Are There Lasting Effects from Long-Term Use of Montelukast?
Hello everyone! To provide some background, I was prescribed montelukast at a young age—around 4 or 5 years old—continuing until I was about 10 or 11. During that time, I experienced significant levels of aggression. Unfortunately, none of the medical professionals we consulted suggested discontinuing the medication or indicated that my symptoms could have been related to its use. This has left me with some unresolved feelings so I’d rather not delve deeper into that right now. Currently, it has been some time since I stopped taking montelukast, but I find myself grappling with certain challenges. While I’m hesitant to elaborate unless absolutely necessary, I’m curious whether anyone knows about potential long-term side effects from prolonged use of this medication during childhood. Thank you so much for your insights! Much appreciated! <3
Food Bolus Lodged for an Extended Period
28-year-old female Currently taking Guanfacine, Prozac, and Lyrica. It’s been quite the rollercoaster for me these past two weeks! To give you some context, I’ve experienced my fair share of food getting lodged in my esophagus several times each week since I was in high school. Typically, it’s not a huge deal; I manage to induce vomiting and continue with my day. However, today was different. I took a single bite of a turkey sandwich, and ever since, I’ve been regurgitating saliva and the sensation of food being trapped persists. The food got stuck around 11 AM, and now it’s already 8 PM. What can I do to alleviate this predicament?
