👉🏼Patent Ductus Arteriosus (PDA): Listen for that continuous “machinery-like” murmur, best at the left upper sternal border. This persists across the cardiac cycle, varying in intensity.✨

👉🏼Pericardial Friction Rub: Imagine two pieces of leather rubbing together—a high-pitched, scratchy sound heard best at the left lower sternal border. It occurs due to inflammation of the pericardium, the sac surrounding the heart✨

👉🏼Pulmonic Stenosis: A harsh crescendo-decrescendo, mid-systolic murmur with a systolic ejection click. This sound happens when the pulmonary valve is narrowed, increasing turbulence from the right ventricle to the pulmonary artery!✨

👉🏼S1 and S2: This is the classic “lub-dub”! S1 marks the closure of the mitral and tricuspid valves, starting systole. While S2 signals the aortic and pulmonic valves, beginning diastole✨

👉🏼S3 (Ventricular Gallop): Is a low-pitched sound occurring right after S1 & S2 — blood flows rapidly into the ventricles during early diastole. While normal in kids, athletes and pregnant people, it could imply heart failure or valve issues for older adults.✨

👉🏼S4 (Atrial Gallop): Occurring just before S1, this low-pitched sound suggests a stiff or hypertrophic left ventricle, commonly seen in conditions like hypertension or aortic stenosis!✨

👉🏼Split S2: A distinct “split” sound occuring when the aortic (A2) and pulmonary (P2) valves close at different times. It’s a normal finding, best heard at the left upper sternal border, especially in younger hearts.✨

👉🏼Ventricular Septal Defect (VSD): A loud, harsh holosystolic murmur at the lower left sternal border, caused by a hole in the heart’s septum, allowing blood to flow between the left and right ventricles!✨
