Failure of a pacemaker is defined by the requirement of repeat surgical pacemaker-related procedures after the initial implantation. Most implanted pacemakers are dual chambered and have two leads, causing the implantation time to take longer because of this more complicated pacemaker system.
An artificial cardiac pacemaker (or artificial pacemaker, so as not to be confused with the natural cardiac pacemaker) or just pacemaker is an implanted medical device that generates electrical impulses delivered by electrodes to the chambers of the heart either the upper atria, or lower ventricles to cause the targeted chambers to contract and ...
Pacemaker syndrome is a condition that represents the clinical consequences of suboptimal atrioventricular (AV) synchrony or AV dyssynchrony, regardless of the pacing mode, after pacemaker implantation. [1] [2] It is an iatrogenic disease—an adverse effect resulting from medical treatment—that is often underdiagnosed.
Arnold Schwarzenegger has become more like his iconic Terminator character after having surgery last week to receive a pacemaker, the 76-year-old actor and former California governor announced ...
Brain death is defined as irreversible cessation of all functions of the entire brain, including the brain stem: coma (with a known cause), absence of brainstem reflexes, and apnea. When doctors take away ventilation systems and patients fail to breathe, move, or show any signs of arousal on their own they are considered brain dead. [ 14 ]
“The pacemaker was implanted due to a low heart rate,” the Royal House of Norway said in a brief statement, adding that the procedure conducted at Hospital Sultanah Maliha was successful.
A pacemaker, also known as an artificial cardiac pacemaker, is an implanted medical device that generates electrical pulses delivered by electrodes to one or more of the chambers of the heart. Each pulse causes the targeted chamber(s) to contract and pump blood, [ 3 ] thus regulating the function of the electrical conduction system of the heart .
Lazarus syndrome (the Lazarus heart), also known as autoresuscitation after failed cardiopulmonary resuscitation, [1] is the spontaneous return of a normal cardiac rhythm after failed attempts at resuscitation. It is also used to refer to the spontaneous return of cardiac activity after the patient has been pronounced dead. [2]
