After the procedure, the patient is monitored to ensure stability of the sinus rhythm. Synchronized electrical cardioversion is used to treat hemodynamically unstable supraventricular (or narrow complex) tachycardias, including atrial fibrillation and atrial flutter.
Transcutaneous pacing is accomplished by delivering pulses of electric current through the patient's chest, which stimulates the heart to contract. [ citation needed ] The most common indication for transcutaneous pacing is an abnormally slow heart rate .
In contrast to defibrillation, synchronized electrical cardioversion is an electrical shock delivered in synchrony to the cardiac cycle. [4] Although the person may still be critically ill, cardioversion normally aims to end poorly perfusing cardiac arrhythmias, such as supraventricular tachycardia. [1] [2]
An arrhythmia is an irregular heartbeat that occurs due to a problem with the electrical activity of your heart. Types of arrhythmia include: Tachycardia. A faster-than-normal heart rate. Bradycardia.
While torsades may spontaneously revert to a normal sinus rhythm, sustained torsades requires emergency treatment to prevent cardiac arrest. [23] The most effective treatment to terminate torsades is an electrical cardioversion – a procedure in which an electrical current is applied across the heart to temporarily stop and then resynchronise ...
Electrical cardioversion can convert AF to normal heart rhythm and is often necessary for emergency use if the person is unstable. [23] Ablation may prevent recurrence in some people. [24] For those at low risk of stroke, AF does not necessarily require blood-thinning though some healthcare providers may prescribe an anti-clotting medication. [25]
If the fast heart rate is poorly tolerated (e.g. the development of heart failure symptoms, low blood pressure or coma) then AVNRT can be terminated electrically using a cardioversion. In this procedure, after administering a strong sedative or general anaesthetic, an electric shock is applied to the heart to restore a normal rhythm. [8]
Illustration of Implantable Cardioverter Defibrillator (ICD) An implantable cardioverter-defibrillator (ICD) or automated implantable cardioverter defibrillator (AICD) is a device implantable inside the body, able to perform defibrillation, and depending on the type, cardioversion and pacing of the heart.
