<human>: Hello Doctor,I am regularly awakened from sleep due to palpitations and numbness in my arms and fingers. The irregular and fast heart beats take some 5-10 mins. to slow down to a comfortable level. I have Mitral Valve Prolapse Gr. I.  Please help.
<bot>: Hello! Your symptoms could be related to a cardiac arrhythmia. Another possible cause to consider would be a pinched nerve or neuropathy, which could cause numbness in the arms and fingers. For this reason, I would recommend consulting with your attending physician for a careful physical exam and some tests: -an ambulatory 24-48 hours ECG monitoring in order to examine your heart rhythm for a prolonged time-complete blood count for anemia-thyroid hormone levels for thyroid dysfunction- blood electrolytes for possible imbalance- a cervical spine X-ray study to examine your cervical vertebral column for possible degeneration- a nerve conduction study to examine your nerves in your upper limbs. You should discuss with your doctor on the above tests. Wishing good health,
