An interventional study of ablation in Premature Ventricular Contractions and Ventricular Tachycardia, sponsored by Shanghai MicroPort EP MedTech Co., Ltd.. Enrolling by invitation at 1 site in China. Open to participants aged 18 Years to 75 Years. Per ClinicalTrials.gov, last updated 2026-03-31.
Sponsored by Shanghai MicroPort EP MedTech Co., Ltd. (formerly part of MicroPort Scientific Corporation) · Not applicable, Interventional, and Treatment
The objective of this study is to evaluate the safety of the dual-energy ablation catheter manufactured by Shanghai MicroPort EP Medical Technology Co., Ltd. in the treatment of tachyarrhythmias.
102 studies on the registry are indexed under Ventricular Premature Complexes; 32 are open to participants now.
This study's planned enrollment of 10 is below the median of 84 across 58 interventional studies indexed under Ventricular Premature Complexes.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.
On an ECG, the QT interval is the time the heart’s lower chambers take to activate electrically and recover in each beat. QTc is that time adjusted for heart rate (QTcF by Fridericia’s formula, QTcB by Bazett’s). Some medicines lengthen it, and a long QTc can raise the risk of a dangerous heart rhythm.
The study may name a correction formula and a limit in milliseconds, often around 450–480.
The New York Heart Association’s four classes of how much heart failure limits physical activity.
Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.
A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.
Stroke symptoms need emergency care at once, even if they go away.

QT and QTc

QTc is that time adjusted for heart rate (QTcF by Fridericia’s formula, QTcB by Bazett’s). Some medicines lengthen it, and a long QTc can raise the risk of a dangerous heart rhythm.

TIA (transient ischaemic attack)
A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.

All enrolled subjects will undergo radiofrequency or pulsed ablation for idiopathic ventricular arrhythmias using the investigational catheter.
Device: ablation
All enrolled subjects will undergo radiofrequency or pulsed ablation for idiopathic ventricular arrhythmias using the investigational catheter.
Also known as: Pulsed Field Ablation Device and CF-Sensing Pulsed Field Ablation Catheter
Success rate of catheter ablation
The primary efficacy endpoints were to evaluate the acute and 3-month follow-up success rate after ablation
Time frame: at end of the procedure, 1-month follow-up, 3-month follow-up
Immediate success rate of ablation
It is defined as the disappearance of the identical outflow tract ventricular arrhythmia that was present pre-ablation, with no inducible sustained identical outflow tract ventricular arrhythmia during 20 minutes of observation following pharmacological and/or electrophysiological stimulation.
Time frame: immediate ablation
