Thank you for your query at DoctorSpring.com.
The description of your symptoms resembles a presyncope along with chest pain and palpitation. It definitely warrants investigation in the form if a 2D echo, a stess test and a 24 hour holter examination. It could be due to anxiety but one should definitely rule out ischemic heart disease and arrhythmias as a cause of these symptoms.
Regarding your recent symptoms , does your face and arm feel heavy? Is there any weakness in your arm? Does your face appear to be asymmetrical?
Please write back and I hope I helped you with some information. Please feel free to discuss further.
