Im 23 and have been experiencing tachycardia, often with shortness of breath, in the evenings and at night. There is no trigger with attacks occurring at rest. I initially put it down to anxiety but Ive been 100% stress-free for weeks and yet the attacks have been consistent. My resting heart rate is about 68, and over 100 during attacks. I have no health problems, take no meds and avoid caffiene. What could possibly be the cause?
Hello, This can be arrhythmia like PSV or atrial fibrillation, where your heart rate suddenly goes up and BP falls. You will need evaluation like ECG, thyroid test and holder monitoring. You should also get one hemoglobin levels done. So visit nearby cardiologist for this investigation. Also, to abort such episodes you should try to cough hard. Till the time your evaluation is complete, you can ask your local doctor for tab collar LA 20 mg. If none of the above is successful then last option is of electrophysiologist studies which is invasive test which can diagnose and treat the arrhythmia permanently in most of the cases. Hope I have answered your query. Let me know if I can assist you further.
