Is S3 or S4 normal in athletes?
A S3 can be a normal finding in children, pregnant females and well-trained athletes; however, a S4 heart sound is almost always abnormal. The third and fourth heart sound (S3 and S4) are two abnormal heart sound components which are proved to be indicators of heart failure during diastolic period.The third heart sound or S3 is a rare extra heart sound that occurs soon after the normal two lub-dub heart sounds (S1 and S2).Definition. The third heart sound (S3) is a low-frequency, brief vibration occurring in early diastole at the end of the rapid diastolic filling period of the right or left ventricle (Figure 24. Synonymous terms include: ventricular gallop, early diastolic gallop, ventricular filling sound, and protodiastolic gallop.A S3 can be an important sign of systolic heart failure, since in this setting the myocardium is usually overly compliant resulting in a dilated LV (see image below). S3 is a low pitched sound. This is helpful to distinguish a S3 from a split S2 which is high pitched.
What is S3 and S4?
CLINICAL PEARL: A S4 heart sound occurs during active LV filling when atrial contraction forces blood into a noncompliant LV. Therefore, any condition that creates a noncompliant LV will produce a S4, while any condition that creates an overly compliant LV will produce a S3, as described above. S3 Compared to Other Heart Sounds A fourth heart sound—S4—is another abnormal heart sound. Like S3, S4 is low-pitched and best heard with the bell of a stethoscope. If present, an S4 also occurs in diastole but in later diastole (right before S1), whereas S3 is heard in early diastole (right before S2).The main difference between S3 and S4 heart sounds is their timing in the cardiac cycle. S3 occurs during ventricular diastole and is associated with blood flowing into the ventricles. S4 occurs during atrial contraction and is associated with the contraction of a stiff or hypertrophic ventricle.
Is the S3 a performance car?
Performance in every journey With 333 PS of power and a new torque splitter concealed within its 5-door hatchback design, Audi S3 Sportback brings performance and everyday usability. Spacious and sporty, it puts you at the forefront of an exhilarating drive.

However, it’s not short of rivals, with the Mercedes-AMG A 35 the Audi’s closest competitor.Common Audi A3 Problems. The Audi A3 is a popular premium hatchback, but like any car, it has some common reliability issues. Owners frequently report problems with the DSG gearbox, suspension creaking, oil pump failures, and fuel line leaks.

Is RS3 faster than A45?
The Audi’s first timed run makes mincemeat of the A45. It also completely destroys its official claim of 3. With launch control engaged, the RS3 hit three figures in 3. That’s supercar performance from a family hatchback. One of the most frequently reported problems with the Audi S3 is related to the engine and turbocharger. Some owners experience issues with the turbo, including reduced performance, strange noises, or even complete failure in severe cases.Audis can typically go up to 200,000 miles or 20 years without major repairs when they’re properly maintained. They’re fairly reliable cars, and Consumer Reports ranks them within the top 10 new car brands when it comes to reliability.The S3 was never short on power, but that hasn’t stopped Audi squeezing an extra 22bhp out of its turbocharged 2. At the same time, the turbocharger received minor tweaks, resulting in improved accelerator response.Both the Audi S3 and Audi S4 come with a four-year/50,000-mile warranty. The S4 earned a predicted reliability rating of three out of five from J. D. Power. The S3 received a rating of only 2. The S4’s higher predicted reliability rating means fewer repairs over the car’s lifetime.
