Summary Statement: “ A pacemaker is small device that is placed in the chest or abdomen and it is used to help control abnormal hearth rhythm. This device uses electrical pulses to prompt the heart to beat at the normal rate” (nhlbi,nih.gov, n.d.).

Rationale: A pacemaker consists of three parts: a battery, a computerized generator, and wires/electrodes. Every time when the heart rhythm is not normal, the computerized generator will sense it, send the signal to the generator to send the electrical impulses to the heart via wires/electrodes (nhlbi,nih.gov, n.d.).

Indications for pacing: atrioventricular block, sick sinus syndrome, bundle branch block, neutrally mediated syncope (rarely), to improve hemodynamic (rarely), and in first-degree AV block with a very long PR interval (Vardas, SImantirakis, & Kanoupakis, 2013).
There are three wires/electrodes in each pacemaker (nhlbi,nih.gov, n.d.):
• Single-chamber pacemaker: carry pulses from the generator to the right ventricle
• Dual-chamber pacemaker: carry pulses from the generator to the right atrium and the right ventricle. The pulses help coordinate the timing between these two chamber contractions.” In the setting of 2:1 atrioventricular block, dual- chamber pacing is recognized as an effective adjunct in the management of long QT syndrome dual-chamber pacing permits A-V synchrony, guarantees a physio- logical heart rate with the facility for physiological tachycardia, prolongs the life of the generator box, and reduces the risk of R on T pacing and consequent torsades de pointes” (McCrossan, d’Uekem, Davis, & Pflaumer, 2015).

• Biventricular pacemaker (cardiac resynchronization therapy device-CRT): carry pulses from the generator to an atrium and both ventricles. “CRT ...

LIFESTYLE CHANGES AFER THE SURGERY (nhlbi,nih.gov, n.d.)
A person with the pacemaker should avoid prolonged contact with all electrical devices that have strong magnetic field, as these devices could potentially prevent the pacemaker to work properly. Some recommendations are that a person with the pacemaker should keep their cellphones in the packet opposite to the site where a pacemaker was placed and to hold a cellphone up to the ear opposite of the pacemaker site.
Magnetic resonance imaging (MRI) shock-wave lithotripsy, and electrocauterization to stop bleeding are three medical procedures that can disrupt the pacemaker.
Normal physical activity is recommended after the recovery. The doctor will check the pacemaker every three months. Battery lifetime is usually 5-15 years and the doctor replaces battery before it starts run low.

Heart Arrhythmias Is The Pacemaker Essay

- The first device that is very effective in treating heart arrhythmias is the pacemaker. The pacemaker is used to treat bradycardia and tachycardia in many patients. The thing to remember is that pacemakers are used to treat a variety of arrhythmia disorders whether it be that the heart beats to quickly, to slowly, or if it has an irregular pattern. The pacemaker helps keep the heart beating at a normal or whatever desired rate due to the hearts inability to beat at a normal heart rate on its own....   [tags: Heart, Cardiology, Heart rate]

Primary Pacemaker Cells Essay

- Primary pacemaker cells located in the central region of the sinoatrial node (SA node) undergo spontaneous diastolic depolarization, which ultimately triggers the action potential (AP) upstroke. The excitatory AP wave front subsequently spreads through adjacent areas of the perinodal region to reach the crista terminalis and atrium. Repolarization of the pacemaker cells allows the cycle to repeat. This inherent cyclic behavior enables the SA node to serve as the normal pacemaker of the heart (7; 12; 14; 26; 57)....   [tags: Medical Science ]

Essay on Pacemaker

- Pacemaker The human heart is an essential organ of the human body. Its sole purpose is to supply the body with oxygen by pumping blood through a complex system of veins and arteries. However, it is often common for the human heart to suffer from various heart conditions, such as a heart block, slow heart beat, heart attack or heart failure. Such heart conditions can lead to weakness, fainting, shortness of breath, or even possibly death. These can usually be treated with medication but in cases where medication is not sufficient, doctors turn to the implantable pacemaker for the solution....   [tags: essays research papers]

PaceMaker Essay

- The PaceMaker I. Introduction Heart disease is among the leading causes of deaths each year. However, many people with heart problems are increasing their longevity with pacemakers. A pacemaker’s main purpose is to keep the heart from beating too slowly thereby preventing the problems associated with slow heart rhythms (passing out, congestive heart failure, and death). Pacemakers are necessary because, while there are many medications that prevent the heart from going too fast, there are only a handful that make the heart beat faster....   [tags: medical health heart disease]
