An artificial cardiac pacemaker, commonly referred to as simply a 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 ...
Pacemaker failure. Pacemaker failure is the inability of an implanted artificial pacemaker to perform its intended function of regulating the beating of the heart. A pacemaker uses electrical impulses delivered by electrodes in order to contract the heart muscles. [1] Failure of a pacemaker is defined by the requirement of repeat surgical ...
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. [1][3] In general, the ...
Transcutaneous pacing (TCP), also called external pacing, is a temporary means of pacing a patient's heart during a medical emergency. It should not be confused with defibrillation (used in more serious cases, in ventricular fibrillation and other shockable rhythms) using a manual or automatic defibrillator, though some newer defibrillators can ...
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 ...
Cardiac contractility modulation. Cardiac contractility modulation is a therapy which is intended for the treatment of patients with moderate to severe heart failure (NYHA class II–IV) with symptoms despite optimal medical therapy who can benefit from an improvement in cardiac output. The short- and long-term use of this therapy enhances the ...
Use of real time monitoring of the heart in an intensive care unit in a German hospital (2015), the monitoring screen above the patient displaying an electrocardiogram and various values of parameters of the heart like heart rate and blood pressure. Electrocardiography is the process of producing an electrocardiogram (ECG or EKG[a]), a ...
Wandering atrial pacemaker may be seen in young, healthy individuals as well as in the elderly and those with lung disease. [2] The cause of wandering atrial pacemaker is unclear. Increased tone from the vagus nerve may factor into the rhythm appearing in young, healthy individuals who exercise. The vagus nerve is a part of the parasympathetic ...
