Researchers at The Ohio State University Wexner Medical Center have found that the human heart has a fail-safe, backup "battery" system that regulates heartbeats. Over 200,000 people in the United States have a pacemaker implanted each year. This translates to an average of an implant about every two and a half minutes.
俄亥俄州立大學醫療中心的研究人員發現人類心臟有一個自動防故障的備份“電池”系統，它掌控著你的心跳。美國每年有20多萬人植入心臟起搏器。也就是說大約每兩分半鐘就有一個人植入心臟起搏器。
The heart's natural pacemaker, known as the sinoatrial node, consists of a battery back-up system with three regions of pacemakers acting as batteries. It also has up to five conduction pathways acting as wires to connect the signal to the heart atria. These findings may help considerably reduce the number of people who need mechanical pacemakers.
心臟自身的起搏器名為竇房結，它含有電池備份系統，共有三個起搏器分區，充當著電池的作用。它還有多達五條的傳導路徑，將信號傳送給心房。這些發現可能大大減少需要植入機械起搏器的人數。
