Question

Quizplus · Accepted Answer

An artificial pacemaker would be needed in cases where the SA node, which is responsible for generating the heart's electrical impulses, is not functioning properly. This can cause irregular heartbeats or even a complete loss of heart rhythm. The pacemaker would help to regulate the heartbeat and ensure that the heart is able to function properly.
