Think of the image like a clock. Start from the 12 o&#8217; clock position and go clockwise. Start with <\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>S1<\/strong>: Closure of AV Valves (Mitral and Tricuspid), <\/li>\n\n\n\n<li><strong>Clicks<\/strong>: Opening of Semilunar valves (Aortic and Pulmonary) causes sounds called clicks. <\/li>\n\n\n\n<li><strong>S2<\/strong>: Closure of Aortic and Pulmonary valves.<\/li>\n\n\n\n<li><strong>Snaps<\/strong>: Opening of AV Valves. <\/li>\n<\/ul>\n\n\n\n<p>So remember as Snap S1, Click S2.<\/p>\n\n\n\n<p>Some other info I thought to drop in here: The closer the Mid diastolic murmur of <strong>Mitral stenosi<\/strong>s is to S2, the faster the Mitral valve has opened and the more severe the case of MS is. Now you may wonder how that&#8217;s possible. You see, the shorter the time between them, the faster the Left Atrial pressure was able to open the MV. Meaning the smaller the pressure difference between LV and LA is. Meaning that LA pressure has risen a lot. Which in turn causes back pressure to the Pulmonary veins and you know the rest (Pulmonary Hypertension, Right Ventricular Hypertrophy (RVH), Features of RVH: Hepatomegaly, Ascites, Edema&#8230;)<\/p>\n\n\n\n<p>Also, a side note as you from the example above. These murmurs can move up and down the cycle based on their severity. So a MDM can become LDM to an extent.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>When it comes to understanding murmurs of the heart, we have a hard time remembering what is what.
