Answer
External means on the outside. Implanted means that the pacemaker goes inside the body.
A permanent pacemaker is surgically implanted in the body to provide long-term heart rhythm management, typically used for chronic conditions like bradycardia. In contrast, a temporary pacemaker is used for short-term heart rhythm support, often in emergency situations or while a patient recovers from surgery, and is typically external or transvenous. The choice between the two depends on the patient's specific needs and the duration of pacing required.
The first pacemaker with plutonium 238 was implanted in Paris (France) in 1970, as a collaboration between Medtronic (USA) and Alcatel (France).
A fixed-rate pacemaker sends electrical prompts to your heart at an unchanging rate. Its drawbacks include that it is somewhat difficult to adapt to a state of physical exertion or emotional arousal.A more advanced type, called a demand pacemaker (there are several types) kicks in after your cardiac function varies outside a pre-set normal rate. It then brings your heartbeat into a more efficient rhythm. (Sinus-rhythm.)A demand pacemaker does not take the place of an implanted defibrillator! If a lifethreatening cardiac arrhythmia develops, it takes a defibrillator -- an implanted one or an external unit used by someone trained to respond -- to correct ventricular fibrillation. If it is not corrected, v-fib is fatal.Demand pacemakes are used to restore a normal heart rate that only becomes abnormal occasionally. A fixed rate pacemaker is used when the problem is always there and the heart won't keep going without constant help.

What is the difference between external and internal communications
what is the difference between the external & internal indicator
what is the difference between the external & internal indicator
internal is in and external is out
its internal and then its external. DEERRR
External is out side emotional is in
difference between external and internal frontier
difference between internal and external dtd
