What happens when pacemaker becomes non - functional?
only auricles contract rhytimically
only venticles contract rhythmically
cardiac muscles do not undergo coordinated rhytmic movements
cardiac muscles contract in coordinated manner rythmically
A pacemaker is a small device that;s placed in the chest or abdomen to help control abnormal heart rhythms.
If pacemaker becomes non - functional then cardiac muscles do not undergo coordinated rhythmic movements.
