The greater use of atropine and epinephrine or external pacing may make transvenous pacing unnecessary by stabilizing patients early in the process of caring for the patient. Some debate exists over the efficacity and reliability of transvenous pacing, especially if the need for permanent pacing is anticipated.
The pacing wire is then connected to an external pacemaker outside the body. Transvenous pacing is often used as a bridge to permanent pacemaker placement. It can be kept in place until a permanent pacemaker is implanted or until there is no longer a need for a pacemaker and then it is removed.
An artificial cardiac pacemaker (or artificial pacemaker, so as not to be confused with the natural cardiac pacemaker) or just pacemaker is an implanted medical device that generates electrical impulses delivered by electrodes to the chambers of the heart either the upper atria, or lower ventricles to cause the targeted chambers to contract and ...
The difference between pacemakers and ICDs is that pacemakers are also available as temporary units and are generally designed to correct slow heart rates, i.e. bradycardia, while ICDs are often permanent safeguards against sudden life-threatening arrhythmias.

These characteristics were incorporated in the next design to be implanted in humans, the model P4, which employed 30 mm 2 area intramyocardial electrodes (and later transvenous pacing electrodes), a very conservative 7.5 volt pulse and for further conservatism a magnetically operated switch which could be actuated from outside the body to ...
As with conventional pacemaker therapy, the cardiac contractility modulation device cannot be implanted if the leads cannot be positioned appropriately in the heart. In cases where there is an artificial heart valve between the right atrium and ventricle (a mechanical prosthetic tricuspid valve), the valve function could be greatly affected by ...
Pacemakers are also sometimes used to regulate the heartbeats in people with congenital heart disease, a group of conditions that affect about 1% of people born in the U.S., according to the ...
Finally, invasive procedures completed by the cardiothoracic anesthesiology fellows include but are not limited to arterial line placement (femoral, axillary, brachial, radial), central venous cannulation (internal jugular, femoral, subclavian), pulmonary artery catheter placement, transvenous pacemaker placement, thoracic epidural analgesia ...
