About this study

Official title: A Randomized Controled Trial of Transcutaneous Magnetic Stimulation of the Stellate Ganglion to Treat Ventricular Tachycardia Storm

Ventricular Tachycardia storm is a medical emergency characterized by three or more episodes of ventricular arrhythmia within 24 hours and associated with a significantly increased mortality and massive health resource utilization. Several therapies are utilized including sympathetic blockade (through deep sedation and beta blockers), antiarrhythmic drugs, implantable cardioverter defibrillator (ICD) reprograming where applicable, and catheter ablation. Despite standard intervention, mortality rates remain high and additional therapeutic options are actively being investigated.

The overall objective of this proposal is to investigate whether transcutaneous magnetic stimulation designed to inhibit the left stellate ganglion can be used in this population. This is a single-center, randomized, sham-controlled trial to assess the efficacy of transcutaneous magnetic stimulation of the left stellate ganglion to treat patients with ventricular tachycardia storm.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Ventricular Tachycardia - Incidence of Ventricular Tachycardia on Inpatient Telemetry Monitoring

    Incidence of ventricular tachycardia on inpatient telemetry monitoring

    Measured: 24-hours following completion of the protocol

Secondary outcomes (8)
  1. Cardioversion - Incidence of ICD Therapies or External Defibrillation Following Stimulation on Device Interrogation or Telemetry

    Incidence of ICD or external defibrillation following stimulation on device interrogation or telemetry

    Measured: 48-hours following completion of the protocol

  2. Number of Patients With Changes in ICD or Pacemaker Lead Impedances

    Number of patients with changes in lead impedance (unit: Ohms) on device interrogation

    Measured: Immediately following completion of the protocol

  3. Number of Patients With Changes in ICD or Pacemaker Lead Thresholds

    Number of patients with changes in lead thresholds (unit: mV) on device interrogation

    Measured: Immediately following completion of the protocol

  4. Number of Patient With Changes in ICD or Pacemaker Lead Sensitivities

    Number of patient with changes in lead sensitivity (unit: mA) on device interrogation

    Measured: Immediately following completion of the protocol

  5. Local Effect From Stimulation - Patient Reported Local Discomfort on Visual Analog Scale (0-10)

    Scores on a visual analog scale (0-10) of discomfort - 0= no discomfort, 1 = minimal discomfort, 10 = most severe discomfort imaginable.

    Measured: Immediately following completion of the protocol

  6. Antiarrhythmic Drugs Used Post Stimulation - Incidence of Antiarrhythmic Drug Use Post Stimulation Per Inpatient Medical Record

    Incidence of antiarrhythmic drug use post stimulation per inpatient medical record

    Measured: 24 hours following completion of the protocol

  7. Number of Patients With Changes in ECG Parameters

    Number of patients with any clinical significant change in PR, QRS, or QT interval before and after stimulation.

    Measured: Immediately following completion of the stimulation

  8. Number of Patients With Changes in Vital Signs

    Number of patients with clinical significant change in heart rate or blood pressure during the procedure.

    Measured: Immediately following the completion of the stimulation

Questions about this trial

What is this clinical trial studying?

A study testing Magstim SuperRapid in people with Ventricular Tachycardia, run by University of Pennsylvania at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Nov 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 5 Jul 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Ventricular Tachycardia - Incidence of Ventricular Tachycardia on Inpatient Telemetry Monitoring (time frame: 24-hours following completion of the protocol). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04043312, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Nov 2022.
