Dear Mack: You may be experiencing benign atrial fibrillation associated with anxiety, stress or severe anemia. It may be harmless and go away on its own with improved physical and mental health. Having a healthy diet including fresh fruits and vegetables along with meditation, yoga or aerobic exercises may help improve your symptoms.
