What Are The Symptoms Of Sinus Tachycardia?

I get severe shortness of breath, dizziness, and shaky during showering and I don t know if it s related to blood pressure changes or heart issues. I just showered and had to sit down in the middle of washing my hair because i felt as if i would faint otherwise. I had a history of sinus tachycardia that i was on atenolol for three years ago that was caused by anorexia nervosa but i spent a year in eating disorder treatment, gained weight, and it got better on its own so my cardiologist took me off the meds and said i no longer need to see him. I checked my heart rate as i was just sitting on the floor of my shower and my heart was racing faster than i could count. Could sinus tachycardia be coming back even though I m much healthier and medically stable now? My bp is always normal when i get it checked now and my average resting heart rate can generally range anywhere from 70-100bpm. I m 30 years old.

Hello and thanks for writing.

I can understand your concern and would try to help you in the best possible way. You problem could be related to PSVT, a condition in which the heart beats too fast leading to improper filling of heart which owes the BP transiently leading to fainting or near fainting episodes.

I suggest you consult a doctor and get yourself evaluated for the condition. A simple ECG with two minute rhythm lead would be a good initial investigation. You may also get a 24 hour ambulatory hotter recording of you ECG that may detect any episode that may otherwise not occur at time of your visit.

Once a diagnosis is confirmed then there are treatment that improve the condition. Firstly one is started on medications which are quite effective. However if medications fail to control it then Radio frequency ablation may be planned.
