Using a standard technique, the left infraclavicular subcutaneous pacemaker pocket was created with sharp and blunt dissection. The 2 j-tipped guidewires were advanced through a left subclavian vein using standard left subclavian venotomy under fluoroscopic guidance. The peel-away sheaths and introducers were advanced over the guidewires, and the guidewires were removed. The pacemaker leads were advanced under fluoroscopic and electrophysiologic guidance into the right ventricular apex and right atrial appendage. The pacemaker leads were seen to function adequately in vivo and were sutured in place with 0 silk. The leads were connected to the pulse generator, which was delivered into the wound in the usual fashion; 2-0 Vicryl suture was used to close the deep tissue layer and a 4-0 running subcuticular suture was used to close the skin. There were no complications of the procedure.…
2. The atrium and ventricle on each side of the heart are separated by one-way valves called ______.…
Discuss the role of endogenous pacemakers and exogenous zeitgebers in the circadian rhythm. 24 Markers…
An endogenous pacemaker is an internal biological clock that controls the way in which many of our biological rhythms behave. Many of these rhythms run on a 24 hour basis, such as the sleep/wake cycle, bodily temperatures and some of our hormones.…
Pulse monitoring allows hospital staff to be aware of one parameter of the patient’s general condition, and, along with the RFID monitoring, can quickly move to the patient’s location and treat the patient when abnormalities in pulse are detected.…
At that time it would trigger the necessary impulse to increase her heart rate again. Stacey was closely monitored over the next 5 years. It was clear that she was not dependent on the pacer, however at the original setting of 60bpm, the device was being used even when it was not needed because it was set to close to normal resting rate. Unfortunately because of this, the batteries to the pacer were drained and needed to be recharged. It was also found that the leads to the pacemaker were corroded with scar tissue and needed replacements as well. The only way to accomplish this is another surgery. A new pacemaker and leads were implanted in November of 1993. This time doctors set the pacer at 40bpm. At this new low setting, that same device had lasted the next 19 years and records show it has rarely been used. Two years ago, doctors began new series of tests to determine the actual need for the pacemaker at this time. It is again time to charge the batteries but test results showed that over a 2 month period, she was on her own heart rhythm and at no time during these 2 months did she use the…
Circadian rhythms are biological rhythms that occur every 24 hours, an example of a circadian rhythm is the sleep-wake cycle, another circadian rhythm is body temperature which is at its lowest at around 36 degrees at night and it peaks in the morning at 38 degrees. Endogenous pacemakers are internal body 'clocks' that will modulate biological rhythms, the SCN is an example of an endogenous pacemaker, it controls our body temperature cycle. Circadian rhythms can also be controlled by exogenous zeitgebers which are external stimuli such as light and temperature.…

The device can give full medical diagnostics. It has a feature called the final notice that can tell when the wearer is going to die. This device initially seemed like a brilliant idea because there would be no incidence of sudden deaths due to health issues. The doctors will be notified about the deteriorating health of their patients. The wearer of the watch can make final arrangements, settle his or her will, say goodbye to their loved ones.…
I've encounter several situations and experienced care to elderly patients. I believe that the education about "PACE and/or "ACE' may have helped many patients and is able to help improve the care to elderly patients. It's been found in a study that older patients cared by nurses trained in geriatrics and in complex caregiving are less likely to be physically restrained and have less readmissions to hospitals and are less likely to be transferred inappropriately from nursing facilities to hospitals. The PACE and Ace program has improved health and reduced costs to elderly patients which is very beneficial for many elderly patients. Every time a patient is being sent to a hospital it costs the patient a big amount of money, and many of these…
2.3.e. What is an EKG? 2.3.f. How can an EKG be used in the diagnosis and treatment of heart disease? EKGs, or electrocardiographs (“electricity heart pictures”) measure the heart’s electrical activity and display it in the form of a picture: P wavesignal passes from SA node (sinoatrial node) to AV node (atrioventricular node), moving across atria QRS intervalsignal passes from AV node through Purkinje fibers & the ventricles contract T wavethe ventricles repolarize & the heart is relaxed…
5. In a partially blocked coronary artery, what happens to vessel radius and what effects does this have on blood flow? What effect would this have on the heart?…
Soldier’s Heart is when you come back from war and are battle wounded and fatigued, your mind has been screwed up because you’ve seen things that no man should ever have to see. Soldier's Heart is almost like P.T.S.D where you have anxiety and flashbacks from that traumatic event. People with Soldier’s Heart will never be the same again. Charlie definitely has Soldier's Heart he displays symptoms of it in a daily basis. First of all he’s basically crippled meaning he's been in a harsh war and seen a few things. In the novel it states that he's old in the heart meaning that he knows he going to die soon and he's good with it, and he's basally old because he is walking around with a cane feeling old but his age of 21 doesn't show it. Charlie…

Functionally single ventricle hearts are a heterogeneous group of cardiac anomalies commonly characterized by a dominant morphological left or right ventricle. There are several subtypes: univentricular atrioventricular connection (such as double inlet ventricle), atriventricular valve severe stenosis or atresia (as in triscuspid or mitral atresia) and severe hypoplasia of one of the in the presence of atrioventricular or ventriculo-arterial connection abnormalities (like unbalanced atrioventricular septal defect or double outlet right ventricle) (Kaulitz & Hofbeck 2005)…
