The normal range for most people is between 60 and 100 BPM, but it's not necessarily concerning to be below 60 BPM, especially at rest. However, if there are persistent symptoms like fatigue and dizziness for no apparent reason, or if other symptoms develop such as loss of consciousness, it would be wise to seek evaluation from a doctor as a precaution. A blood pressure of 120/70 mmHg is considered normal. A heart rate of 53 BPM is generally not worrisome as long as there is no discomfort or other concerning symptoms present. It's always important to listen to your body and seek medical attention if needed.
