Transvenous cardiac pacing , also called endocardial pacing , is a potentially life saving intervention used primarily to correct profound bradycardia. It can be used to treat symptomatic bradycardias that do not respond to transcutaneous pacing or to drug therapy. Transvenous pacing is achieved by threading a pacing electrode through a vein into the right atrium, right ventricle, or both. This means of pacing the heart is not as popular as other means of pacing see transcutaneous pacing , implanted pacemaker , epicardial pacing because it is a temporary solution to pace the heart and yet involves a similar level of risk of bleeding as a more permanent solution like placing an implanted pacemaker. For patients who present in an emergency setting with symptomatic bradycardias, usually drugs like atropine or sympathomimetic drugs e.g. epinephrine, dopamine, etc. can be used to increase the heart rate to an adequate level until the underlying cause of the bradycardia can be isolated and then, possibly, a permanent pacemaker can be placed. For patients for whom transvenous pacing is chosen, the procedure is done at the bedside with a local anesthetic alone or in conjunction with conscious sedation . The pacing electrode is advanced through the vein under flouroscopic and electrocardiographic guidance. An x ray after the procedure is always obtained to confirm placement of the pacing electrode. The greater use of atropine and epinephrine or external pacing may obviate the need for transvenous pacing 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. References Urden, L., Stacy, K., and Lough, M.

How to date September 2009 Pacing A reasonably easy and quick method of measuring distance in the field is by pacing http www.cnr.berkeley.edu departments espm extension PACING.HTM . Pacing is a method used to measure a distance and is often used with a sighting or hand compass . Most commonly, pacing is split up into segments, such as chains, which are set measures of distance. By determining your own pace, distance can easily be estimated. Calibrating To estimate your own pace a measure of known distance, such as 66 one chain or 132 two chains , should be marked in a straight line on level ground. One pace is defined as two footsteps. Pace the distance several times and record the number of paces it takes to walk the distance each time. If the distance paced is longer than one chain, the number of paces must be divided by the number of chains paced. To determine the average distance of one pace divide the total distance walked by the number of paces it takes to pace that distance. See pacing chart for paces per chain and feet per pace http www.ces.ncsu.edu forestry pdf WON won39.pdf . Applications Common uses of pacing consist of measuring tree height or measuring the distance between plots. Pacing saves time but is not as accurate as using a tape measure and can be affected by terrain such as steep slopes, rocky areas, streams, and thick brush. A common practice in pacing when an obstacle is encountered is to offset or pace around the obstacle. However, sometimes pacing around an obstacle is not always an option. Good pacing can only be accomplished by practice. Knowing the distance of your pace will help to ensure the accuracy and precision of pacing distances. Other uses Pacing can also be used with a map. In the field, pacing can be used to accomplish the correct distances ... produces opportunities for pacing to be applied to record accurate data.

Transcutaneous pacing also called external pacing is a temporary means of pacing a patient s heart during a medical emergency. It is accomplished by delivering pulses of electric current through the patient s chest, which stimulates the heart to contract. The most common indication medicine indication for transcutaneous pacing is an abnormally slow heart rate . By convention, a heart rate of less than 60 beats per minute in the adult patient is called bradycardia . Not all instances of bradycardia require medical treatment.

This is based on Mental image visualization where the mind is assumed not to be able to tell the difference between a scenario which is real and one which has been clearly visualized. The theory is that, having visualized positively, when the subject encounters the situation again in reality the visualized experience will serve as a model for how to behave, even though this experience was imagined. The mind cannot tell the difference between the visualization and reality so it accepts the visualization as reality and Accommodation psychology makes the change .

orphan date September 2008 Introduction Diaphragm Pacing , also known as phrenic nerve pacing , is the rhythmic application of electrical impulses to the Thoracic diaphragm diaphragm , resulting in respiration for patients who would otherwise be dependent on a mechanical ventilator . This concept was originally referred to as electrophrenic respiration, although the Food and Drug Administration identifies the device as a diaphragmatic phrenic nerve stimulator . A phrenic nerve pacemaker, with electrodes placed around the phrenic nerve, is a Class III medical device, which requires premarket approval. An newer approach has been developed and approved by the FDA see diaphragmatic pacemaker at Case Western Reserve University which places the electrode in the diaphragm using minimally invasive surgical technique. Indications for Use According to Medicare United States Medicare , phrenic nerve stimulators are indicated for selected patients with partial or complete respiratory insufficiency and can only be effective if the patient has an intact phrenic nerve and diaphragm. Medicare National Coverage Determinations Manual , Chapter 1, Part 2, Section 160.19 Common patient diagnoses for phrenic nerve pacing include patients with spinal cord injury , central sleep apnea ie, Ondine s curse , and diaphragm paralysis. Surgery The surgery is performed by placing an electrode around the phrenic nerve , either in the neck ie, cervically , or in the chest ie, thoracically . This electrode is connected to a radiofrequency receiver which is implanted just under the skin. An external transmitter sends radio signals to the device by an antenna which is worn over the receiver. For the cervical surgical technique, the phrenic nerve is approached via a small 5 cm incision slightly above, and midline to, the clavic. The phrenic nerve is then isolated under the scalenus anticus muscle. For the thoracic surgical technique, a small 5 cm incisions over the 2nd or 3rd intercostal space.
