[/INST] Hello,Racing heart about 110 bpm is considered Tachycardia (high heart rate). As you have experienced from last week till now, then, you should consult a cardiologist as soon as possible. The immediate cardiac check-up is highly recommended:• ECG• Echocardiogram• Holter monitoring Until you see a cardiologist, I highly recommend to take Chamomile and Valerian supplement to help settle your anxiety down.Hope I have answered your query. Let me know if I can assist you further.Regards,Dr. Nirav Nimavat </s>
