The heartbeat may become too slow, irregular or abnormal. This condition can make a person feel tired, dizzy, weak or even cause fainting. In such situations a pacemaker can help control the heart rhythm. A pacemaker is a small medical device designed to monitor the hearts electrical activity and provide electrical impulses when needed. Traditional pacemakers have already saved millions of lives. However modern technology is taking pacemakers to the next level. Smart pacemakers combine cardiac technology with sensors, wireless communication, data analysis and intelligent algorithms. Instead of simply providing electrical stimulation thes...
