It involves forceful exhalation against a closed airway, which increases intrathoracic pressure and triggers the vagus nerve to enhance parasympathetic activity, slowing heart rate.<br \/>\nMy father was saved from an extended episode of SVT by a cardiologist who was called to the ER to help since the electric shocks had no effect. As soon as my father followed the doctor&#8217;s instructions, which involved the method described below, his heart rhythm returned to normal.<br \/>\nI called it a miracle, and I was so grateful. I considered ourselves lucky or blessed to have had that doctor around.<\/span><\/span><\/span><\/div>\n<div class=\"css-146c3p1 r-bcqeeo r-1ttztb7 r-qvutc0 r-37j5jr r-evnaw r-eaezby r-b88u0q\" dir=\"ltr\"><strong><span class=\"css-1jxf684 r-bcqeeo r-1ttztb7 r-qvutc0 r-poiln3\"><span class=\"css-1jxf684 r-bcqeeo r-1ttztb7 r-qvutc0 r-poiln3 r-a8ghvy\">How to Perform the Valsalva Maneuver<\/span><\/span><\/strong><\/div>\n<ol dir=\"ltr\" start=\"1\">\n<li>\n<div class=\"css-146c3p1 r-bcqeeo r-1ttztb7 r-qvutc0 r-37j5jr r-1inkyih r-hbpseb r-16dba41\" dir=\"ltr\"><span class=\"css-1jxf684 r-bcqeeo r-1ttztb7 r-qvutc0 r-poiln3 r-b88u0q r-a8ghvy\"><span class=\"css-1jxf684 r-bcqeeo r-1ttztb7 r-qvutc0 r-poiln3\"><span class=\"css-1jxf684 r-bcqeeo r-1ttztb7 r-qvutc0 r-poiln3 r-a8ghvy\">Standard Valsalva<\/span><\/span><\/span><span class=\"css-1jxf684 r-bcqeeo r-1ttztb7 r-qvutc0 r-poiln3 r-a8ghvy\"><span class=\"css-1jxf684 r-bcqeeo r-1ttztb7 r-qvutc0 r-poiln3\">:<\/span><\/span><\/div>\n<ul>\n<li>\n<div class=\"css-146c3p1 r-bcqeeo r-1ttztb7 r-qvutc0 r-37j5jr r-1inkyih r-hbpseb r-16dba41\" dir=\"ltr\"><span class=\"css-1jxf684 r-bcqeeo r-1ttztb7 r-qvutc0 r-poiln3 r-a8ghvy\"><span class=\"css-1jxf684 r-bcqeeo r-1ttztb7 r-qvutc0 r-poiln3\">Sit or lie down comfortably.<\/span><\/span><\/div>\n<\/li>\n<li>\n<div class=\"css-146c3p1 r-bcqeeo r-1ttztb7 r-qvutc0 r-37j5jr r-1inkyih r-hbpseb r-16dba41\" dir=\"ltr\"><span class=\"css-1jxf684 r-bcqeeo r-1ttztb7 r-qvutc0 r-poiln3 r-a8ghvy\"><span class=\"css-1jxf684 r-bcqeeo r-1ttztb7 r-qvutc0 r-poiln3\">Take a deep breath and hold it.<\/span><\/span><\/div>\n<\/li>\n<li>\n<div class=\"css-146c3p1 r-bcqeeo r-1ttztb7 r-qvutc0 r-37j5jr r-1inkyih r-hbpseb r-16dba41\" dir=\"ltr\"><span class=\"css-1jxf684 r-bcqeeo r-1ttztb7 r-qvutc0 r-poiln3 r-a8ghvy\"><span class=\"css-1jxf684 r-bcqeeo r-1ttztb7 r-qvutc0 r-poiln3\">Pinch your nose closed and keep your mouth shut.<\/span><\/span><\/div>\n<\/li>\n<li>\n<div class=\"css-146c3p1 r-bcqeeo r-1ttztb7 r-qvutc0 r-37j5jr r-1inkyih r-hbpseb r-16dba41\" dir=\"ltr\"><span class=\"css-1jxf684 r-bcqeeo r-1ttztb7 r-qvutc0 r-poiln3 r-a8ghvy\"><span class=\"css-1jxf684 r-bcqeeo r-1ttztb7 r-qvutc0 r-poiln3\">Bear down as if having a bowel movement or exhale forcefully against the closed airway for 15\u201320 seconds.<\/span><\/span><\/div>\n<\/li>\n<li>\n<div class=\"css-146c3p1 r-bcqeeo r-1ttztb7 r-qvutc0 r-37j5jr r-1inkyih r-hbpseb r-16dba41\" dir=\"ltr\"><span class=\"css-1jxf684 r-bcqeeo r-1ttztb7 r-qvutc0 r-poiln3 r-a8ghvy\"><span class=\"css-1jxf684 r-bcqeeo r-1ttztb7 r-qvutc0 r-poiln3\">Release and breathe normally.<\/span><\/span><\/div>\n<\/li>\n<\/ul>\n<\/li>\n<li>\n<div class=\"css-146c3p1 r-bcqeeo r-1ttztb7 r-qvutc0 r-37j5jr r-1inkyih r-hbpseb r-16dba41\" dir=\"ltr\"><span class=\"css-1jxf684 r-bcqeeo r-1ttztb7 r-qvutc0 r-poiln3 r-b88u0q r-a8ghvy\"><span class=\"css-1jxf684 r-bcqeeo r-1ttztb7 r-qvutc0 r-poiln3\"><span class=\"css-1jxf684 r-bcqeeo r-1ttztb7 r-qvutc0 r-poiln3 r-a8ghvy\">Modified Valsalva<\/span><\/span><\/span><span class=\"css-1jxf684 r-bcqeeo r-1ttztb7 r-qvutc0 r-poiln3 r-a8ghvy\"><span class=\"css-1jxf684 r-bcqeeo r-1ttztb7 r-qvutc0 r-poiln3\"> (more effective for SVT):<\/span><\/span><\/div>\n<ul>\n<li>\n<div class=\"css-146c3p1 r-bcqeeo r-1ttztb7 r-qvutc0 r-37j5jr r-1inkyih r-hbpseb r-16dba41\" dir=\"ltr\"><span class=\"css-1jxf684 r-bcqeeo r-1ttztb7 r-qvutc0 r-poiln3 r-a8ghvy\"><span class=\"css-1jxf684 r-bcqeeo r-1ttztb7 r-qvutc0 r-poiln3\">Perform the standard maneuver for 15 seconds.<\/span><\/span><\/div>\n<\/li>\n<li>\n<div class=\"css-146c3p1 r-bcqeeo r-1ttztb7 r-qvutc0 r-37j5jr r-1inkyih r-hbpseb r-16dba41\" dir=\"ltr\"><span class=\"css-1jxf684 r-bcqeeo r-1ttztb7 r-qvutc0 r-poiln3 r-a8ghvy\"><span class=\"css-1jxf684 r-bcqeeo r-1ttztb7 r-qvutc0 r-poiln3\">Immediately after, lie flat and have someone raise your legs to a 45-degree angle for 45 seconds to enhance venous return and vagal stimulation.
