In July last year, I had sudden palpitations (pulse 150). ER diagnosed sinus tachycardia and hypertension. ECG and Trop T were negative ER sent me home and prescribed me to take lonazep 0.5 mg but i never took it I was sacred for some reason I don't know why. Since then, I often get sharp left-sided chest pain, dizziness, palpitations, and occasional breathlessness. Over the year, I did ~10 ECGs during episodes (all normal), 2D Echo normal. Lipids: LDL 113, HDL 49, triglycerides 106. Thyroid (TSH, FT4), glucose (HbA1c, estimated average glucose), CBC all normal. BP is controlled on medication. Two cardiologists and three MD physicians said I’m fine. I have BMI ~42. I also experience occasional GERD symptoms. Despite reassurance, symptoms persist. Could these be related to hypertension, obesity, or another cause?
