[|Human|] Hi.  My daughter woke up feeling very unwell, trembling with a high heart rate 109.  She feels very weak and when she woke up her legs were numb.  She also feels a little dizzy.  I checked her BP and got 117/81 but the pulse was 109.  She really feels bed.  Any advice??
[|AI|]  Hello and thank you for using Chat Doctor. I carefully read your question and I understand your concern. You should not worry about. I will try to explain and give you my opinion. You should know that normal heart rate ranges between 50-100 beat for minute. When it exceeds 100 we talk about sinus tachycardia. There are different causes of sinus tachycardia. Simple emotional stress, excessive coffee consumption or pathologies like anemia, hyperthyroidism, electrolyte imbalances, cardiovascular anomalies, active infections or hormonal changes. When a person experience tachycardia It's normal to feel anxiety, palpitations, difficulty in breathing deeply, dizziness. If I was the treating doctor I would recommend some examination like a cardiac echo to evaluate heart function and valves, a full blood analyze to exclude anemia, hyperthyroidism or electrolyte imbalance and a holder rhythm monitoring to evaluate mean heart rate during day and night. Only after this we can be sure if is something to be treated or just a stressed period or hormonal changes that soon will pass. Hope I was helpful. Wish your daughter good health. Best regards, Chat Doctor.
