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 ...
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. The ICD is the first-line treatment and prophylactic therapy for patients at risk for sudden cardiac ...
The subcutaneous ICD delivers therapy without the need for wires implanted in the heart. Depending on heart condition, 1, 2 or 3 leads will be placed in the heart. Once the leads are put in place, they are attached to the heart wall for optimal connectivity. The subcutaneous ICD leaves the heart and blood vessels untouched and intact.
The FDA approved the OPTIMIZER Smart System, which delivers cardiac contractility modulation therapy, as indicated to improve 6-minute hall walk distance, quality of life, and functional status of NYHA Class III heart failure patients who remain symptomatic despite guideline directed medical therapy, who are in normal sinus rhythm, are not indicated for cardiac resynchronization therapy, and ...
Normal heart rate varies substantially between individuals, and many athletes in particular have a relatively slow resting heart rate. [2] In addition, the heart rate is known to naturally slow with age. It is only when bradycardia presents with signs and symptoms of shock that it requires emergency treatment with transcutaneous pacing.
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]
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.
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 the heart's cells. [23] Treatment to prevent recurrent torsades includes infusion of magnesium sulphate, [24] correction of electrolyte imbalances ...
