Final answer:
An artificial pacemaker that is implanted for the purpose of terminating atrial tachycardias is known as antitachycardia pacing.
Step-by-step explanation:
A pacemaker is a medical device that is implanted in the chest or abdomen to regulate the heartbeat. It is commonly used to treat certain heart conditions that involve abnormal heart rhythms or conduction disorders. The pacemaker monitors the heart's electrical activity and delivers electrical impulses to the heart muscle when necessary to maintain a regular and coordinated heartbeat.
An artificial pacemaker that is implanted for the purpose of terminating atrial tachycardias is known as antitachycardia pacing. This type of pacemaker is programmed to deliver electrical impulses to the heart that can help terminate the rapid heart rate and restore normal sinus rhythm.
