What are external pacemakers?
An External Cardiac Pacemaker that is also known as a Transcutaneous or Artificial Pacemaker is an electrodes-based medical device that is used to regulate the contractility of myocardiocytes to maintain adequate heart rate and so cardiac output.
What is implantable pacemaker?
Overview. A pacemaker is a small device that’s placed (implanted) in the chest to help control the heartbeat. It’s used to prevent the heart from beating too slowly. Implanting a pacemaker in the chest requires a surgical procedure. A pacemaker is also called a cardiac pacing device.
What is the difference between internal and external pacemakers?
External pacemakers have manual controls to determine the mode of operation and to adjust pacing rate, pulse width, delivered current, etc.; implantable pacemakers are programmed or reprogrammed using a “wand” (held over the implanted device outside the body) that transmits data to the pacemaker.
How do external pacemakers work?
Stimulators. Cardiac stimulation is carried out by delivering a pulse of electrical current through the electrode catheter from an external pacemaker (stimulator) to the cardiac surface. Such an electrical impulse depolarizes cardiac tissue near the pacing electrode, which then propagates through the heart.
What are the two types of pacemakers?
Single-chamber pacemaker: Uses a single wire attached to one chamber of your heart. Dual-chamber pacemaker: Uses two wires attached to two chambers of your heart.
Where is pacemaker implanted?
A pacemaker insertion is the implantation of a small electronic device that is usually placed in the chest (just below the collarbone) to help regulate slow electrical problems with the heart. A pacemaker may be recommended toensure that the heartbeat does not slow to a dangerously low rate.

How are pacemakers implanted?
Surgical-based (epicardial) approach: A surgeon creates a small incision in your chest and inserts the lead(s) through that incision, and then attaches the lead(s) to your heart. The surgeon then connects the lead(s) to the pacemaker. The pacemaker is inserted into a “pocket” under the skin of your abdomen.
How is pacemaker inserted?
Once the anesthetic has taken effect, the physician will make a small incision at the insertion site. A sheath, or introducer, is inserted into a blood vessel, usually under the collarbone. The sheath is a plastic tube through which the pacer lead wire will be inserted into the blood vessel and advanced into the heart.

What is a pacemaker insertion? A pacemaker insertion is the implantation of a small electronic device that is usually placed in the chest (just below the collarbone) to help regulate slow electrical problems with the heart.
What is the most common pacemaker?
Dual-chamber pacemaker – With this device, two pacing leads are implanted (one in the right ventricle and one in the right atrium); this is the most common type of implanted pacemaker.
