The modified Valsalva maneuver works by briefly changing pressure inside your chest. When you strain, less blood returns to the heart. When you release, blood suddenly rushes back in. Your body senses that change and triggers a strong vagal (calming) response, which slows signals through the heart’s electrical system. That pause can be enough to break the loop and reset the rhythm back to normal. Simple physiology — using your body’s own reflexes to stop an abnormal heartbeat. #SVT #HeartHealth
