Catheter ablation is a procedure that uses radio-frequency energy or other sources to terminate or modify a faulty electrical pathway from sections of the heart of those who are prone to developing cardiac arrhythmias such as atrial fibrillation, atrial flutter and Wolff-Parkinson-White syndrome.
PVCs can be distinguished from premature atrial contractions because the compensatory pause is longer following premature ventricular contractions, in addition to a difference in QRS appearance. [20] In some people, PVCs occur in a predictable pattern. Two PVCs in a row are called doublets and three PVCs in a rows are triplets.
Pulsed field ablation (PFA) is a non-thermal (not using extreme heat or cold) method of biological ablation (removal of structure or functionality) utilizing high-amplitude pulsed (microsecond duration) electric fields to create irreversible electroporation in tissues. [1] [2] It is used most widely to treat tumors or cardiac arrhythmias. [3]
Therefore, RF catheter ablation is often a safe and effective choice for treatment VT and PVCs causing TIC. [1] [5] In cases where other treatment strategies fail, AV node ablation with permanent pacemaker implantation can also be used to treat the tachyarrhythmia. [6] [9]
Findings from 1994 indicate success rates of as high as 95% in people treated with radiofrequency catheter ablation for WPW. [27] If radiofrequency catheter ablation is successfully performed, the condition is generally considered cured. Recurrence rates are typically less than 5% after a successful ablation. [26]
Catheter ablation wasconsidered to be a first-line treatment method for many people with typical atrial flutter due to its high rate of success (>90%) and low incidence of complications, [1] although pulsed field ablation now offers a non-thermal option. This is done in the cardiac electrophysiology lab by causing a ridge of scar tissue in the ...
Hims recaps the year's most surprising health findings, from the growing number of adults who consider monogamy optional to those who would rather lose weight than be debt free.
New types of catheters, such as lattice and saline-enhanced radiofrequency catheters, provide more precise and longer-lasting tissue damage. Additionally, cardiac imaging technologies like MRI can help identify abnormal areas causing arrhythmias and evaluate the success of the ablation procedure. [24]
