What additional sign can be observed in patients with left ventricular hypertrophy?

In patients with left ventricular hypertrophy (LVH), the presence of an S4 gallop is particularly significant. The S4 heart sound, also known as the atrial gallop, occurs when the atria contract to force blood into a stiff or hypertrophied ventricle. This indicates that the left ventricle has become less compliant, a condition often associated with LVH.

The S4 sound is typically best heard just before the first heart sound (S1), and its presence can be indicative of underlying issues, such as long-standing hypertension, aortic stenosis, or other conditions that can lead to an increase in ventricular wall thickness. Its significance lies in that it helps clinicians identify problems with ventricular filling and compliance, making it a useful diagnostic tool in patients with suspected heart disease.

While elevated jugular venous pressure, palpitations, and abdominal pain may arise in various cardiovascular conditions, they are not specifically related to the presence of LVH. The S4 gallop, however, provides direct insight into the ventricular function and is a classic sign associated with hypertrophied myocardium.
