A papillary fibroelastoma is a primary tumor of the heart that typically involves one of the heart valves. [1] Papillary fibroelastomas, while considered uncommon, make up about 10 percent of all primary tumors of the heart. [2] They are the third most common type of primary tumor of the heart, [3] behind cardiac myxomas and cardiac lipomas.
Asplenia with cardiovascular anomalies, also known as Ivemark syndrome and right atrial isomerism, [1] is an example of a heterotaxy syndrome.These uncommon congenital disorders are characterized by defects in the heart, spleen and paired organs such as the lungs and kidneys.
An ectopic pacemaker located in the atria is known as an atrial pacemaker and can cause the atrial contraction to be faster. [10] An ectopic pacemaker situated near the AV node and the septum is known as a junctional pacemaker. [11] The pacemaker that is operating in the ventricles is known as the ventricular. [12]
A normal chest X-ray after placement of an ICD, showing the ICD generator in the upper left chest and the ICD lead in the right ventricle of the heart. Note the 2 opaque coils along the ICD lead. The process of implantation of an ICD system is similar to implantation of an artificial pacemaker. In fact, ICDs are composed of an ICD generator and ...
[1] [5] Most myxomata arise sporadically (90%), and only about 10% are thought to arise due to inheritance. [6] About 10% of myxomata are inherited, as in Carney syndrome. Such tumors are called familial myxomata. They tend to occur in more than one part of the heart at a time, and often cause symptoms at a younger age than other myxomata.
The ILR monitors the electrical activity of the heart, continuously storing information in its circular memory (hence the name "loop" recorder) as electrocardiograms (ECGs). Abnormal electrical activity - arrhythmia is recorded by "freezing" a segment of the memory for later review.
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 ...
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 .
