ClinConnect Summary

This clinical trial is studying a new approach called the Modified Valsalva Maneuver (MVM) to help patients with a heart condition known as paroxysmal supraventricular tachycardia (SVT). SVT causes the heart to beat very quickly, and the goal of this trial is to see if the MVM can more effectively restore a normal heartbeat compared to the standard Valsalva Maneuver. The MVM involves sitting up straight, taking a deep breath and blowing out for about 15 seconds, then lying down with legs elevated for another 15 seconds. The research suggests that this method may work better in stopping SVT episodes and could reduce the need for medications.

To participate in the trial, you need to be an adult between 18 and 70 years old who has been diagnosed with SVT and is visiting the emergency department. Unfortunately, this trial cannot include those who have certain heart issues, like atrial fibrillation, or other specific medical conditions. If you join the study, you can expect to undergo the MVM as part of your care in the emergency department. It’s important to know that while the MVM may be more effective, some patients have reported more side effects, though these were not significantly higher. The trial aims to gather more information on how well this method works in real-life settings and to understand better how to improve care for patients with SVT.

Eligibility criteria

• Inclusion Criteria:
• • All adult patients that present to the emergency department
• • Only true SVT will be included.
• Exclusion Criteria:
• • ECG more suggestive of atrial fibrillation or atrial flutter
• • Age \< 18 years or \> 70 years
• • Broad QRS, including known aberration
• • Known aneurysm (aortic, intracranial or elsewhere)
• • Known aortic stenosis
• • Known glaucoma
• • Hemodynamic instability requiring immediate electric cardioversion.
• • Patients that experience an SVT in the hospital but are never admitted to the emergency department (e.g., patients in the cardiac care unit), as the MVM protocol will be only implemented in the prehospital setting and ED.
