[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. ECG I'd basically a screening tool for heart diseases. It is not 100% diagnostic. Some, heart diseases can be missed if we consider only ECG. In your case, we should rule out arrhythmia (rhythm disturbances in heart). Arrhythmia can cause faster heart beats without chest pain. So get done 2d echo and Holder monitoring (24 hours continuous recording of ECG). If both these are normal then no need to worry about arrhythmia or other heart diseases. Sometimes stress and anxiety can also cause similar symptoms. So avoid stress and tension, be relaxed and calm. Don't worry, you will be alright. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
