NCT ID: NCT04905199 Recruiting - Tachyarrhythmia Clinical Trials

Temporary Transvenous Pacemaker Placement by Intracavitary Electrocardiogram Monitoring

Start date: March 25, 2021
Phase:
Study type: Observational

Traditional temporary pacing catheter insertion by intracavitary electrocardiogram (IC-ECG) monitoring which only monitoring tip polar, the negative one. The investigators modified the technique by monitoring both negative and positive polar which will be precisely locating catheter tip and indicating the direction of the catheter tip. Extensively used temporary pacing catheter tip has two electrodes which are about 1 cm apart. Distal electrode is negative (-) and active, proximal electrode is positive (+) and indifferent. Investigators use both distal (-) and proximal (+) electrodes which can be attached to any two of the V leads, record as V(-) and V(+). Monitoring positions of the electrodes by V(-) and V(+) could provide more information about the tip position. Comparing the QRS amplitudes between V(-) and V(+), when catheter tip enters right ventricle chamber: the case of V(-) > V(+) infers tip toward apex ventricle wall ; conversely, the case of V(-)<V(+) indicates tip directs to outflow tract. The investigators hypothesis this monitoring will help precisely placement.

NCT ID: NCT04858698 Recruiting - Bradycardia Clinical Trials

Reduction Or Elimination Of Radiation During Implantation of Cardiac Devices Using Ultrasound

RADICAL USE
Start date: July 30, 2021
Phase: N/A
Study type: Interventional

Specialized equipment is required to put pacemakers in the heart. This requires use of radiation to see the wires or leads being implanted in the heart. Repeated radiation use can result in permanent injury to the patient and to the doctor. The investigators aim to investigate if they can use ultrasound to guide and help in the implantation of leads into the heart. Ultrasound is a safe method and requires only a small handheld probe and a small screen to see different structures in the heart. If ultrasounds proves successful as a tool to reduce radiation then this would be very useful technical breakthrough. It would help develop smaller centres where pacemakers can be implanted without purchasing xray equipment and expensive setups.

NCT ID: NCT04632641 Completed - Atrial Fibrillation Clinical Trials

Suture Closure AFtEr VEIN Access for Cardiac Procedures (SAFE-VEIN) Trial

SAFE-VEIN
Start date: April 23, 2021
Phase: N/A
Study type: Interventional

Primary objective: To compare the safety and efficacy of closure strategies post venous access procedures. Hypothesis: We anticipate that the use of a venous closure device will decrease the time to hemostasis (TTH), time to ambulation (TTA) and time to discharge (TTD) compared to conventional methods of closure following venous access procedure.

NCT ID: NCT01170611 Completed - Clinical trials for Sinus Node Dysfunction

Prevention of Atrial Arrhythmia in Patients Without Atrioventricular (AV) Conduction Disease

Start date: July 2004
Phase: Phase 4
Study type: Interventional

This clinical investigation is a prospective, single-blinded, randomized trial. The primary objective concerns the safety and effectiveness of the AAIsafeR mode with the preventive algorithms.

NCT ID: NCT00740272 Terminated - Clinical trials for Brady-tachy Syndrome

Af Ablation In Brady-Tachy Syndrome

Alternative
Start date: March 2008
Phase: N/A
Study type: Interventional

The aim of the study is to evaluate the impact of atrial fibrillation ablation in patients presenting a brady-tachy syndrome on the AF burden. The hypothesis of the study is that AF ablation prevents not only from AF episodes recurrence but also from bradycardic episodes.

NCT ID: NCT00224341 Recruiting - Sick Sinus Syndrome Clinical Trials

Arrhythmia Restart Prevention and RatE STabilization in Atrial Fibrillation

Start date: November 2003
Phase: Phase 4
Study type: Interventional

The objective of this trial is to show the therapeutic efficacy of the preventive pacing therapies of the Selection 9000 and Vitatron T70 DR pacemakers, dedicated to handle atrial fibrillation (AF). Two new algorithms (post-AF response and ventricular rate stabilization [VRS]) will be assessed in a combined pathway, compared to a control group. The efficacy of the overall available therapies to prevent AF and its symptoms will then be assessed also.
