[|AI|]  Hello and thanks for writing. I can understand your concern and would try to help you in the best possible way. You heart palpitations could be related to a combined effect of lack of sleep, excessive coffee intake or smoking to keep you awake i at night or any medication you may be taking. I suggest you consult a doctor and get a baseline cardiac evaluation with an ECG or ambulatory hotter study to rule out any cardiac arrhythmia. In the meanwhile you may decrease your coffee intake and smoking and try to change your shift as it may help with your palpitations.
