question: Hello doctor, I am 18 years old. I have benign palpitations from the age of 15. I am getting extremely frustrated and anxious. I went to a cardiologist today and have no peace. All he said was my Holter monitor shows benign PVC, PAC, bigeminy, trigeminy, and my echocardiogram came out fine and he is sending me for a stress test for the heck of it. But I am not worried about this, but I am more worried about my palpitations now because they cluster. It can be two minutes of every heart beat being a palpitation, especially when I lie down and when I an anxious. Can you please let me know if it is normal for them to come in clusters? I am so scared I seriously need your reassurances because my cardiologist just ignored me when I asked. Please help.  I attached a picture from an app, my heart rate is 80 at that time. Please reassure me.
