A pacemaker is a small, battery-operated device which senses when one’s heart is beating irregularly or too slowly. It sends a signal to one’s heart that makes one’s heartbeat at the correct pace.
BNP Vice-Chairman AZM Zahid Hossain told UNB that Moudud has been suffering from various diseases, including anaemia, blood pressure, thyroid and heart problems.
