Analysis of the causes for faults in a pacemaker.
A pacemaker produces electrical impulses or stimuli to regulate the heartbeat when the heart’s natural pacemaker ( SA/ AV node) fails to coordinate with our heart. An artificial pacemaker is a wireless device that needs to be implanted in the patient’s body so that heart can keep pace with the regular functionalities of our system. Pacemaker malfunction is quite a severe issue as its failure involves life and death. The significant problems are failure to pace the appropriate cardiac chamber, the problem with detecting intracardiac signals, pseudomalfunction, etc. It can be further subdivided into more issues as per the fishbone below. Refer to the fishbone template below to list the vital causes of a pacemaker malfunction.

Our objective is to adopt an organized approach to arrange the potential causes of any incident or problem. We have made an effort to show the likely issues leading to a pacemaker malfunction. We have designed a simple fishbone and made the cause analysis procedure visually accessible to make it easy for everyone to understand the most like issues and causes.
