Heart rate: Normally heart rate responds to exercise or physiologic demand levels. Usually we don't see it go over 180-200 even with high levels of exercise. This level while tolerated by 'normals' may be dangerous in patients with heart disease or other forms of disease. In other words, one number doesn't fit all.

Slow heart beat: If you don't have any symptoms like dizziness, pre-syncope, syncope or fatigue or chest pain or shortness of breath, then you are ok. But you complained of chest pain. Hence it should be treated. Its etiology should be elicited. Thyroid problems and blocks in heart arteries should be ruled out. Consult your physician.

It depends: On how you feel and what the cause is. Some people in that situation will feel dizzy or pass out. Some will need a pacemaker. Please see your doctor. There are some tests you likely need.

Depends: It depends on how long, what time of day, and whether there are any symptoms present. It's not unusual to drop to 30 during sleep or to have a brief spell of 30 while awake. It also depends what caused it: the EKG will have clues.

Variable range: The adult average resting heart rate is variable, depending on underlying health, aerobic fitness, etc. The typical range would be between 60 and 90 beats per minute. People who are in good aerobic health can be in the 50's. Professional bicyclists can have resting heart rates in the 40's to upper 30's per minute.
