I have panic disorder problem and took course of medicine paroxitine in the past. Sometimes, I still get panic/anxiety attacks and I got an anxiety attack 2 days ago, my heart was beating fast than normal around 105 but I noticed some arrhythmias while checking pulse around palm while having anxiety attack for 5 minutes. I felt some of the pulse were long or slow between normal pulse. After that I got normal till now and my pulse is normal. Question is: can panic attack/anxiety cause arrhythmia not tachycardia..? Or is it any cardiac issue..? I did ECG one day before and it was normal
