Understanding Exercise-Induced Tachycardia, Low Blood Pressure, and Orthostatic Symptoms
A 19-year-old female, weighing 125 pounds, does not smoke and is currently using Accutane and Claritin to manage her allergies. She engages in moderate to high-intensity workouts at irregular intervals, lacking a regular exercise schedule but striving to stay active. Her Apple Watch indicates an average walking heart rate of 120, though she often experiences rates between 130 and 140 during her walks. Recently, during a running session, she recorded her heart rate peaking at 190, which caused a fluttering sensation that concerned her. Over the past few weeks, she has become more attuned to her bodily sensations post-exercise, and this awareness has caused some anxiety. A friend measured her blood pressure, revealing readings of 90/68 while she was lying down and 82/62 when she stood. She has also noted similarities between her symptoms and those of a friend diagnosed with POTS. Occasionally, she experiences hot flashes and dizziness upon standing up, further adding to her discomfort.

It's understandable to feel concerned about your symptoms, especially given your heightened awareness of how your body responds to exercise. Your experiences with elevated heart rates, low blood pressure, and dizziness could point to several potential issues, including postural orthostatic tachycardia syndrome (POTS) or simply exercise-induced changes. Let's break it down and explore what you can do.
Key Points
- You are experiencing elevated heart rates during exercise and low blood pressure, particularly when standing.
- Symptoms like dizziness and hot flashes can be related to these changes.
- Awareness of your symptoms can lead to anxiety, which is also valid and important to address.
Explanation
Elevated heart rates during exercise are common but can become worrisome if they peak excessively, like the 190 bpm you experienced. Intrinsically, this reflects your body's response to exertion. However, consistently low blood pressure, especially when standing (orthostatic hypotension), can lead to dizziness or a fluttering sensation. POTS is characterized by a significant increase in heart rate upon standing, along with symptoms like dizziness or lightheadedness, which seems relevant based on your symptoms.
Given that you’re using Accutane, which can influence hydration and may sometimes affect metabolism and cardiovascular responses, these factors should be considered as well.
Next Steps
-
Hydrate Well: Make sure you're drinking plenty of fluids, especially before and after exercise. Dehydration can worsen both heart rate and blood pressure issues.
-
Gradual Movements: When transitioning from lying down to standing, do so slowly to allow your body to adjust. Consider doing ankle pumps or tensing leg muscles while sitting or lying down before standing to improve blood flow.
-
Regular Exercise Routine: Try to establish a consistent exercise routine. Starting with lower intensity and gradually increasing can help your body adapt better to physical activity without overwhelming your cardiovascular response.
-
Monitor Symptoms: Keep a diary of your workouts, heart rates, and any symptoms (dizziness, fluttering, etc.) that occur along with your blood pressure readings. This can help identify patterns and triggers.
-
Address Anxiety: It’s important to address any anxiety you may be feeling about these sensations. Practices such as mindfulness, meditation, or speaking with a supportive friend can help.
If your symptoms persist or worsen, particularly the extreme heart rate or concerning blood pressure readings, it's advisable to seek medical advice to tailor a plan specific for you.

Struggling to Understand My Symptoms
I'm a 22-year-old male weighing around 145 pounds, and I've recently stopped taking high-dose Ibuprofen (800mg) prescribed for Costochondritis. Lately, I have been experiencing a rapid heartbeat, palpitations, discomfort in my chest, along with feelings of pain radiating into my arms and jaw. Additionally, I've had ongoing back pain, persistent lightheadedness, and occasional nerve sensations in my head. For about a month now, I've also been dealing with sporadic nerve discomfort throughout the upper part of my body. To investigate these troubling symptoms, I've undergone multiple ECGs, had various blood tests, x-rays, and wore a Holter Monitor for 48 hours. A CT scan was also performed due to my dizziness, but all the results came back normal, with no underlying issues detected by the doctors. During my latest visit to the emergency room, I was discharged with a diagnosis of Costochondritis, which could explain some of the chest discomfort I've been having for the last month. However, this doesn't clarify the symptoms I’ve been experiencing for the past six months prior. Recently, I've felt somewhat better over the past week, but the occasional nerve pains have returned. I'm curious if anyone can share insights on what might be happening. Could it really be attributed solely to anxiety? The pains and palpitations appear even when I’m relaxed, such as when I’m using my phone, reading, or gaming. It's becoming increasingly frustrating, and I wish to find a definitive explanation for my condition, as I'm starting to doubt that anxiety alone is the root cause of these discomforts.
Am I Just Being Overly Concerned?
At the age of 61, I have generally enjoyed good health throughout my life, but the past year and a half has presented me with several health challenges. It all began with acid reflux, which ultimately led to me undergoing a partial Nissen Fundoplication procedure last June. Thankfully, that surgery has been quite effective, and I am relieved that I chose to go through with it. Nonetheless, during the lengthy period it took to receive an accurate diagnosis and treatment, I experienced significant fatigue. Medical investigations revealed that I suffer from iron deficiency anemia, prompting another endoscopy along with a capsule endoscopy. This examination uncovered Angiodysplasia in my small intestine. Although I've been receiving iron infusions to manage my anemia and low ferritin levels and was expecting to feel an improvement, I am still not at my best. As a registered nurse, I find myself questioning whether my profession is aiding my understanding or only complicating my concerns. I continue to feel uneasy, as I have not fully grasped the reasons behind my lingering discomfort. Recently, I've started to suspect I could have Scleroderma, given some additional symptoms I’ve been experiencing—my fingers sometimes swell in the morning, I occasionally feel like there’s something amiss with my lungs, and I have developed spider veins on my face, along with a history of reflux. Am I overreacting, or could these signs indicate a collection of related issues warranting further investigation by a medical professional? I appreciate any insights or thoughts you might be willing to share.
