Hello and thank you for using HCM.I carefully read your question and I understand your concern. I will try to explain 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 experience high blood pressure values during physical and emotional stress so it is mandatory to judge on mean values during day and night. Hypertension in young ages usaly has a secondary couse that might be a renal disease, an endocrine problem or a cardiovascular anomaly. Normal heart rhythm range between 50-100 beat for minute.When it exceed 100 beat we talk about sinus tachycardia. It might happen from simple emotional stres, excessive coffee or energy drink consumption,patologyes like anemia, hyperthyroidism or endocrine problems. 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,your urinary chatecolamins, thiroid hormones, an abdominal echo to evaluate renal structure and the most important one a holter pressure and rhythm monitoring. Only after this we can better judge if we have a problem and how to deal with it. Hope I was helpfull. Best regards.
