Have you ever experienced your heart suddenly racing at 180 or even 200 beats per minute, terrifying, unpredictable, and completely out of your control? In this video, I discussed the Modified Valsalva Maneuver the official first-line technique recommended by the American College of Cardiology that can stop a racing heart episode in seconds without any medication. He also explains the critical difference between SVT and AFib, when to call 911 immediately, what happens in the ER when the maneuver does not work, and the permanent solution most SVT patients never hear about.
