Update on health issues

I'm not moving as fast as I want on regaining my health.  I have developed spike in heartbeat.  It has reached to 126 at one time.  I am on a beta blocker now for it.  Well, this week, I have spent three days stacking boxes and it was quite a workout.  Yesterday, I had a real problem with my heart skipping.  So today I am calling my doctor and asking for a referal to a cardiologist.  I want an opinion from a cardiologist.  Since heart trouble runs in the family, time to get proactive.  And I am back to walking 4 miles a day.
