Hello and thank you for using HCM.I carefully read your question and I understand your concern. I will try to explain you and give my opinion. You should know that this palpitation are related whith a rhythm issue. They are electrical impulses that generates in parts of the heart different from normal sinus rhythm.They cause premature heart contaction and you might experience palpitation, flattering sensation, anxiety, difficulties in breathing deeply, dizziness ect. The causes of this rhythm issue might be different to simple emotional stress or pathologys like anemia, hyperthyroidism, electrolyte imbalances, cardiovascular disease, valvular problems, active infections or pericardial effusion. So, in your case it is mandatory to evaluate the severity of valvular problem and pericardial effusion.They might be the main reason of your palpitations, breathing difficulty ect. According to blood pressure values you should know that we talk about hypertension if we have mean values above 140 / 90 mmHg.A person might have high value during stress so it is mandatory to judge on mean values. Treating the causing factor improves all the associated symtoms. So, if I was your treating doctor I would recommend some examination like a cardiac echo, a full blood analyze, your thyroid hormones and a holter rhythm and pressure monitoring. After all this we can judge and know how to treat the problem. Hope I was helpfull. Best regards, Dr.Ervina.
