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 ______.…
The single-chamber model is defined by its light weight, ease of operation, durability, and dependability. It is intended for temporary atrial or ventricular pacing and supports synchronous (VVI, AAI) and asynchronous (VOO, AOO) operating modes.…
Mr. M, 52, comes to the ED complaining of intermittent palpitations, shortness of breath, and lightheadedness. Triage takes Mr. M back into the treatment area after a quick evaluation. His vital signs are BP, 140/80; pulse, 148 and regular; respirations, 18; and SpO2, 97% on room air.…
Discuss the role of endogenous pacemakers and exogenous zeitgebers in the circadian rhythm. 24 Markers…
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.…
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.…
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.…

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…
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…
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)…
