Cardiac pacemaker

During one year, the heart initiates approximately 32 million heartbeats to pump blood around the body, beating a total of 60-80 times per minute at a normal pace. It is a highly efficient organ and constantly works to keep our blood circulation going and ourselves alive. The high efficiency of the heart pumping system originates in a conductive system, which is linked to the Sinoatrial (S-A) and Atrioventricular (A-V) node. The Sinoatrial node, also known as the natural cardiac pacemaker, is located in the upper part of the right atrium and initiates the contractions of the cardiac muscle by producing special electrical impulses which act as an activation signal for the heart to contract. This occurs in form of a depolarization, which firstly…

Implantable cardiac pacemakers By virtue of the light weight and high theoretical capacity of lithium metal, lithium primary batteries have been widespread in health-improving medical devices since the successful implantation of the first lithium-powered pacemaker in 1970s.29, 30 Depending on the power level, implantable medical device primary batteries fall into several categories: low-rate batteries outputting microwatts of power such as batteries for cardiac pacemakers and hearing devices;…

-Your heart beat works from the electrical impulses that travel down pathways through your heart. The normal sinus rhythm is initiated by the SA node also known as the sinoatrial node. It is also known as the hearts natural pacemaker due to the fact it beat 100 bpm. The electrical activity then spreads through the wall of the atria and as a result causes them to contract before it reaches the AV node. From there the AV node conducts electrical impulses from the atria to the ventricles while…

right bundle branch, the electrical depolarization must go through the left bundle branch and put the RBBB at rest, so it takes a while longer than it should. It’s amazing how the heart is so powerful and have many parts that contribute to how it function and how people live. In regards to the waves, it gives a visual of how a person heart rate goes up and down and to look for any normal or abnormal heart rhythm. Since the P wave is the sinoatrial node, which is the pacemaker of the…

Patient Care Technology Identification and Definition A leadless pacemaker is a small, self-contained unit that is placed on the inside wall of the heart through a thin, flexible catheter. In other words, it is a pacemaker without the leads (Bongiorni et al., 2016). A pacemaker is a small device that is placed in the chest or abdomen to help control abnormal heart rhythms. This device uses low-energy electrical pulses to prompt the heart to beat at a normal rate (60-100 beats per minute)…

TB incidence has fallen by an average of 1.5% per year since 2000. This needs to accelerate to a 4–5% annual decline to reach the 2020 milestones of the "End TB Strategy" (“Key”). If these statistics continue, the discoveries made in the 20th century will be the reason these advancements now are successful. The second major advancements in cardio during the 20th century were also through instruments and tools. Pacemakers had been thought of but never executed until 1958. A pacemaker is an…

was the day his autonomy was taken away from him, and all the decisions were put on his wife who was his power of attorney. As Jeffrey’s condition got worse, his wife made the life altering decision to place a pacemaker to keep her husband alive, and since that day she and her daughter have fought to end his suffering. The issue is whether to respect the power of attorneys autonomy and comply with the desire to deactivate the pacemaker or if it is beneficent to do so. The article “What Broke…

industry has its superiority to override. When comparing the drugs, medical devices are relatively less side effects and controllable such that when dealing with cancer, using chemotherapy is better than taking tones of pills that the effects on patients are easily to control and observe. Moreover, one of the critical point for medical devices is that the time of discovery new devices is shorter than a new drug is found (AusBioTech, 2015, para 5). Compare to healthcare products, the treatment of…

In this paper you will find information about pacemakers and defibrillators. Pacemakers and defibrillators are devices that help keep the heart in rhythm. If the heart starts to beat to slow or to fast it will send an electrical shock to get it back on pace. When you get one or both devices implanted in you will need to have regular check-up with the doctors, these should not affect your daily life. Later on in the article you read that you may be allowed to still participate in fast paced…

The Corporate Veil In the Law and Order episode “The Corporate Veil” the standard of morality is cheapened by the insatiable need for easy money. Many characters throughout the episode displayed that behavior in varying degrees. In addition, we also see how laws not being in place allow such activities to go on. In the episode we meet a young boy named Roberto Martinez, who two years ago had an operation for the installation of a pacemaker. Tragically Roberto dies and the police are called…
