The anxiety or panic attack cannot lead to Arrythmias. As you correctly said that the symptom of anxiety is teachycardia( raised heart rate) not arrhythmia and you have confirmed with ECG ( which picks up any irregularities in the pulse rate or rhythm). And another symptom of anxiety is being hyper vigilant so you might have felt the pulse beat is getting irregular in between.So take treatment for anxiety and next time if you have any such experience you can consult at a hospital with emergency facility. This will reassure you

Hello You are young It’s completely understandable to feel alarmed when your heart rhythm seems “off” during a panic attack. From a psychological standpoint, anxiety and panic can absolutely cause what feels like arrhythmia. The surge of adrenaline during a panic episode can lead to sensations like skipped beats, pounding heart, or irregular rhythms, especially when you’re hyper-focused on your pulse. These are usually harmless and known as somatic symptoms of anxiety—your body reacting to perceived threat, even if there’s no actual danger. Since your ECG came back normal and these symptoms resolved on their own, it strongly suggests that this was anxiety-related and not a structural heart issue. The mind-body connection is powerful, and anxiety can create very real physical symptoms. But the good news is, this gives you control—you can work on reducing these episodes through therapy, grounding techniques, and if needed, medication support. You’re not alone in this, and these sensations are more common than most people admit. Let’s work together to break the fear loop and help your body feel safe again.
