Artificial Pacemakers
Pacemakers send electrical pulses to help your heart beat at a normal rate and rhythm. Pacemakers can also be used to help your heart chambers beat in sync so your heart can pump blood more efficiently to your body. This may be needed if you have heart failure.
A pacemaker is a small, battery-powered device that prevents the heart from beating too slowly. You need surgery to get a pacemaker. The device is placed under the skin near the collarbone. A pacemaker also is called a cardiac pacing device. There are different types of pacemakers.
Failure of a pacemaker is defined by the requirement of repeat surgical pacemaker-related procedures after the initial implantation. Most implanted pacemakers are dual chambered and have two leads, causing the implantation time to take longer because of this more complicated pacemaker system.
Indications for Artificial Pacemakers
- Adams Strokes Attack (Syncope secondary to third degree AV block)
- Third degree AV Block with slow ventricular rate
- Acute myocardial infarction with Mobitz AV block
- Right bundle branch block plus left anterior hemi block or left posterior hemi block (particularly Acute MI)
- New left bundle branch block associated with acute MI
- Symptomatic sinus bradycardia unresponsive to medical therapy
- Atrial fibrillation with slow ventricular rate in the patient who requires digitalis therapy.
- Carotid sinus syncope
- Suppression of dysrhythmias (atrial or ventricular tachydysrhythmias)
- Dysrhythmias occurring during or after cardiac surgery
- Sick sinus syndrome
- Prophylaxis before surgery in patients with history of cardiac arrest or AV blocks.
Temporary Introduction Sites
- Subclavian vein Antecubital vein
- Femoral vein
- Jugular vein.
