Cardioversion is a medical procedure by which an abnormally fast heart rate (tachycardia) or other cardiac arrhythmia is converted to a normal rhythm using electricity or drugs. Synchronized electrical cardioversion uses a therapeutic dose of electric current to the heart at a specific moment in the cardiac cycle , restoring the activity of the ...
Dronedarone has been termed a "multichannel blocker". [citation needed] However, it is unclear which channel(s) play a pivotal role in its success. [9]Thus, dronedarone's actions at the cellular level are controversial, with most studies suggesting an inhibition in multiple outward potassium currents including rapid delayed rectifier, slow delayed rectifier and ACh-activated inward rectifier. [10]
Treatment may be with specific physical maneuvers, medications, or, rarely, synchronized cardioversion. Frequent attacks may require radiofrequency ablation, in which the abnormally conducting tissue in the heart is destroyed. AVNRT occurs when a reentrant circuit forms within or just next to the atrioventricular node.
The most common treatments are medications and surgery to repair the damaged blood vessels in your brain. Valvular heart disease Heart valve problems may be treated with medications or surgery.
Antiarrhythmic agents, also known as cardiac dysrhythmia medications, are a class of drugs that are used to suppress abnormally fast rhythms (tachycardias), such as atrial fibrillation, supraventricular tachycardia and ventricular tachycardia.
Amiodarone is an effective, antiarrhythmic-of-choice in achieving cardioversion to sinus rhythm in critical care populations with new onset atrial fibrillation (NOAF). However, other anti-arrhythmic agents may exert superior rhythm control, rate control and lower mortality rate which may be more favourable than amiodarone in specific cases.
The test can also detect heart abnormalities such as arrhythmias, and conditions affecting electrical conduction within the heart such as various types of fascicular blocks. [3] A "normal" stress test does not offer any substantial reassurance that a future unstable coronary plaque will not rupture and block an artery, inducing a heart attack ...
A 16-year-old New Mexico boy was arrested Saturday morning after he allegedly gunned down his parents and teenage siblings and then drunkenly called 911 to confess to the quadruple homicide ...
