Hello and thank you for using HCM.I carefully read your question and I understand your concern. I will try to explain you something and give you my opinion. You should know that we talk about hypertension if we have mean value that exceeds 140 / 90 mmHg.A person might have high value during emotional and physical strees so its mandatory to judge on mean values. If we catch high values than it is mandatory to treat them becouse blood pressure left untreated slowly modify heart muscle. About fast beats they have to do whith a rhythm issue. It might be a simple sinus tachycardia, meaning that the heart beats over 100 beat for minute or a different kind of arythmia like atrial fibrillation, supra ventricular tachycardia ect. The causes of this rhythm issue also might be different like simple emotional stress, coffee or alcohol consumption or pathologys like anemia , hyperthyroidism, electrolyte imbalances , active infections, heart disease ect. So, if I was your treating doctor I will recommend some examination like an electrocardiogram , a cardiac echo to evaluate heart function and walls, a full blood analyze to exclude anemia, hyperthyroidism or electrolyte imbalance and of course a holter pressure and rhythm monitoring to evaluate your rhythm tendency and your pressure values. Of course you have to continue your blood pressure medication and sinus infection becouse it might be the cause of your symtoms. I will advise you to go to the emergency room only if you have episodes whith chaotic and very fast beats because in this case it might an arythmia that needs medical attention. Other wise just take your medications regularly and make the ambulatory examination that I mention before. Hope I was helpfull. Best regards, Dr.Ervina.
