Nasal Swab vs. Valsalva Maneuver for Heart Rate Episodes
Part of Heart & circulation clinical trials.
This study compares two simple, non-medication methods to stop sudden fast heartbeat episodes: a nasal swab technique versus a breathing exercise. Both are safe first-line treatments, and this trial helps doctors understand which works better.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older
- You have been diagnosed with supraventricular tachycardia (fast, regular heartbeat originating above the heart's main chambers) confirmed by an electrocardiogram (ECG)
- Your blood pressure is stable (at least 90/60 mmHg) and you are alert and oriented
- You do not have Wolff-Parkinson-White syndrome or pre-excitation patterns on your ECG
- You can safely lie down and have a nasal swab performed, with no recent nasal surgery, active nosebleeds, or nasal growths
- You are not pregnant and can provide written consent to participate

Other trials that look related to this one.
This Phase 2 trial tests whether an at-home nasal spray medicine called etripamil can help children who have episodes of a specific type of fast, irregular rhythm caused by an electrical “AV node” circuit. It mainly targets certain kids with past or confirmed episodes on heart testing.
This trial tests a way to stop a specific fast heart rhythm (AVNRT) using a freezing treatment guided by an ultrasound camera inside the heart. It may help people whose heart rhythm episodes come from a “slow pathway” wiring circuit.
This trial compares two medicines, adenosine and verapamil, to see which works better for stopping a sudden fast heart rhythm called SVT. If you have an episode of SVT that is stable enough to not need emergency shock treatment, you may be able to join.
This study tests a procedure called cardioneuroablation for people whose fainting or very slow heartbeat doesn't improve with other treatments. If you are under 60, have no other major heart conditions, and have not had ablation before, it might be an option to reduce or stop your fainting spells.
This trial tests a procedure called cardioneuroablation to treat severe fainting (reflex syncope) that hasn't been helped by other treatments. The goal is to see if it reduces fainting without causing dangerous heart rhythm problems.
This study compares two catheter-based procedures to treat ventricular tachycardia (VT), a fast, dangerous heart rhythm. It looks to see which approach works better at reducing repeat VT events in people with weakened heart pumping.
