Doctor, let me ask, feeling short of breath when sleeping, heart beating very fast is a sign of disease?

Hi doctor! I was diagnosed by a doctor with heart palpitations, but these days, heart palpitations appear more often than ice cream, followed by heavy fatigue in the chest, difficulty breathing, frequent startling sleep. So the doctor asked me, is the rapid heartbeat often accompanied by fatigue, shortness of breath and startling sleep, is it dangerous, doctor? Thank you doctor!

I often have heart palpitations, before it was rare and difficult to recognize. However, recently, the frequency of heart palpitations occurs continuously and I can feel it clearly. Several times when I went to the doctor, the doctor said that I had a fast heart rate. I want to ask the doctor if tachycardia is dangerous?

I am currently having heart problems with symptoms like heart palpitations, shortness of breath, trouble sleeping. My heart rate reading is currently 118/min. The doctor asked me if my heart rate 118/min is okay? Seek advice from doctors. Thank you!

Hi doctor! Recently, I suddenly felt my heart beat faster. So the doctor asked me what to do when my heart rate increases rapidly? Ask your doctor for advice. Thank you.
