Hello and welcome

I appreciate your concern

Heart rate of such a pattern is abnormal. It comes under the definition of bradycardia.

The holter monitor findings would be required to determine if the bradycardia was just incidental or related to a serious cause such as heart block. If no such patterns are repeatedly observed then no intervention would be needed.

An Echocardiogram should also be advised in this regard.

Let me know if you have any queries

would HR go up and down for an hour? Is heart block BAD?

Detailed Answer:
Hello again.

The pulse should ideally be checked physically/ hands on rather than through a pulse oximeter.

A heart block is a rhythm abnormality in which the heart beats slowly as the electrical signals that make the heart contract are partially or totally blocked. It should be ruled out as arrhythmias can evolve quickly and often have ischemic causes.
