Synchronized electrical cardioversion is used to treat hemodynamically unstable supraventricular (or narrow complex) tachycardias, including atrial fibrillation and atrial flutter. It is also used in the emergent treatment of wide complex tachycardias, including ventricular tachycardia , when a pulse is present.
The medications used in animals for atrial fibrillation are largely similar to those used in humans. [188] Electrical cardioversion is occasionally performed in these animals, but the need for general anesthesia limits its use. [188] Standardbred horses appear to be genetically susceptible to developing atrial fibrillation. [189]
Junctional tachycardia is a form of supraventricular tachycardia characterized by involvement of the AV node. [1] It can be contrasted to atrial tachycardia.It is a tachycardia associated with the generation of impulses in a focus in the region of the atrioventricular node due to an A-V disassociation. [2]
Ionizing radiation may be used to treat other cancers, but this may, in some cases, induce a second form of cancer. [74] Radiation can cause cancer in most parts of the body, in all animals, and at any age, although radiation-induced solid tumors usually take 10–15 years, and can take up to 40 years, to become clinically manifest, and ...
The following is a list of cancer types. Cancer is a group of diseases that involve abnormal increases in the number of cells , with the potential to invade or spread to other parts of the body. [ 1 ]
An implantable cardioverter-defibrillator (ICD) is a battery-powered device that monitors electrical activity in the heart, and when an arrhythmia is detected, can deliver an electrical shock to terminate the abnormal rhythm. ICDs are used to prevent sudden cardiac death (SCD) in those who have survived a prior episode of sudden cardiac arrest ...
The AV node is the structure that controls how electrical signals travel between the upper chambers (atria) and lower chambers (ventricles). During normal sinus rhythm, these signals pass through only one pathway, known as the fast pathway. The fast pathway conducts signals quickly but has a longer rest period before it can send another signal.
Torsades de pointes, torsade de pointes or torsades des pointes (TdP; also called torsades) (/ t ɔːr ˌ s ɑː d d ə ˈ p w æ̃ t /, [2] French: [tɔʁsad də pwɛ̃t̪], translated as "twisting of peaks") is a specific type of abnormal heart rhythm that can lead to sudden cardiac death.
