Hi, normal is 60 - 100 and generally it slows as we age. Sinus tachycardia can occur with anemia, anxiety, hyperthyroidism, fever and dehydration. It may not be related to a cardiac disorder. Since your tests are normal, your symptoms of hyperventilation, palpitations and dizziness could be attributed to Chronic Hyperventilation Syndrome. It is characterized by hyperventilation for no apparent reason, frequent yawning, palpitations, dizziness, sweating, fainting, depression, and cold sweats. Please discuss this with your doctor am sure he will provide further assistance. In the meantime you could practice breathing exercises and good relaxation techniques like yoga and meditation. Regards.
