Ever feel like heart sound is just a chaotic jumble of thumps and whooshes? You're not alone. When you're listening to a heart, the main players are S1 (the "lub") and S2 (the "dub"). Think of them as the basic rhythm section of the heart.

Normally, your heart gives you a bit of a break: the period of
🔹diastole (when the heart fills) is longer than
🔹systole (when it contracts).
This timing usually helps you find your bearings.

But here’s where it gets tricky: when a patient has tachycardia (a fast heart rate), those phases start blending together. It’s like the drummer just sped up the tempo, and suddenly, what was a clear "lub-dub... lub-dub" becomes a rapid "lubdublubdub," making it super easy to misinterpret what you're actually hearing.

🧐So, how do you stay oriented? Keep it simple: S1 is louder at the apex (bottom of the heart, think mitral/tricuspid valve closure), and S2 is louder at the base (top of the heart, aortic/pulmonic valve closure).

📱🩺Train your ear to listen for that loudest point, even when the rhythm speeds up. It’s your internal compass in the cardiac jungle.

Left ventricular remodeling is not just a change in cardiac “geometry” – it is a complex process of structural and functional myocardial adaptation.

Remodeling can be:
👉 Physiological (adaptive):
Concentric hypertrophy without fibrosis
(seen in athletes, pregnancy, normal growth)

👉 Pathological:
Concentric remodeling or eccentric hypertrophy, accompanied by activation of neurohormonal systems, interstitial fibrosis, and cardiomyocyte loss
(hypertension, valvular heart disease, myocardial infarction, etc.)

Pathological remodeling is the substrate for the development of heart failure and life-threatening arrhythmias.

During resuscitation, recognizing and addressing reversible causes of cardiac arrest is essential. These treatable factors often drive the arrest, and acting quickly can make a meaningful difference in outcomes.

👉 Know the rhythm, but always hunt the cause — it can change the outcome.

Did you know?
Cold weather causes blood vessels to constrict, activates stress responses, and coincides with lifestyle changes, all of which combine to produce measurable increases in blood pressure during winter.

This is a well-documented seasonal phenomenon, not a myth.

👂The sound of the pulmonic valve closing can be heard as the second (P2) or pulmonary component of the second heart sound (S2). In normal and persistent splitting of S2, the aortic component is first, and the pulmonary component is second. In paradoxical splitting, however, the pulmonary component is heard first.

❗️The pulmonary component is usually quieter than the aortic component.

A very loud P2 can be caused by two reasons:

🩺 Pulmonary hypertension
🩺 Atrial septal defect

With valvular pulmonary stenosis, we can hear a systolic rising-falling expulsion murmur. A pulmonary ejection murmur may also be present, which disappears on inspiration. With pulmonary regurgitation, we can hear a diastolic murmur.

Big news! Most Stethophone Pro features (besides AI) are now available to everyone without a prescription.

Stethophone Pro, our flagship medical device, has received another FDA 510(k) clearance, meaning the U.S. Food and Drug Administration has formally cleared the product’s use as a medical tool.

This clearance opens the door for broader access to advanced cardiac assessment directly on a smartphone.
☝For users, that means Stethophone Pro’s capabilities are now more widely available - empowering both clinicians and everyday people to collect and share high-quality cardiac sound data wherever they are.

Our mission is to make state-of-the-art cardiac screening as simple and accessible as using a smartphone.
The future of proactive care is here.

01/12/2026

Let’s get back to basics: heart disease screening isn't just a box to tick—it's your early warning system. We’re taking a closer look at why screening for valve health, in particular, is one of the most proactive steps you can take for your heart.
