Hello, I am a 25 year old female. Two days ago I went to the ER bc my heart was pounding at a rate of 115 and I had shortness of breath. Once I rested I was ok. They didnt find anything and told me I probably had a flu. I just had another one of these episodes. I was laying un a blanket bc I was very cold and shivering. Then I felt like I was very nervous. My heart rate elevated. I tried to relax and fell asleep. When I awoke my heart was almost normal but I was very weak and shaking. My bp is also slightly elevated. Is this normal or is there reason for concern? Thank you.
Hello, Most likely this is anxiety and palpitations, however we need to rule out cardiac arrhythmia like PSV or atrial fibrillation, in which heart rate suddenly goes up and also suddenly decreases. Blood pressure falls during these episodes and one has dizziness, fainting, blackouts, sometimes syncope.  Usually ECG is normal as it is usually done in between the episodes. ECG done during episodes will show abnormality. You will need 24 hour holder monitoring. So visit nearby cardiologist for this investigation.  Also, hemoglobin and thyroid test should be done. Ln order 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 once a day.
