Learn about the phonocardiogram (PCG), a high-fidelity plot of heart sounds over time. PCGs are useful tools that can be used to determine overall heart health through the detection of otherwise subaudible sounds and murmurs.

A heart murmur is an abnormal heart sound that could be caused by congenital and acquired structural abnormalities, but may sometimes also be present in healthy hearts.

Telemedicine can help reduce the burden on healthcare systems caused by COVID-19.

Read an overview of the stethoscope, a medical device used for auscultating the internal sounds of the body.

Learn the basics of cardiac electrical signals

Learn the the cardiac cycle and how it starts with the sinus node and atrial depolarization

Eko's telemedicine plan allows providers to virtually examine their patients' cardiac and pulmonary health as if they were standing at their bedside.

Learn how healthcare providers can screen for diseases like pneumonia while staying safe from COVID-19

Master Cardiac Basics like Cardiac Anatomy

Abnormal or unusual heart sounds may indicate illness. Auscultating (hearing) those sounds well depends greatly upon chest location.

Why don’t healthcare providers use their stethoscopes? The answer, I fear, is complex and sad.

Learn the basics of mitral regurgitation. (MR) is a condition in which the mitral valve does not close properly, allowing blood to flow backward from the left ventricle into the left atrium during systole.

Step-by-step on using Bluetooth stethoscopes for wireless auscultation

Learn about valvular heart diseases like Aortic stenosis

Learn how cardiovascular health is effected by COVID-19.

Learn about systolic murmurs

Learn the value of electronic stethoscopes, enhanced analog stethoscopes with features such as noise cancellation, filtering, and amplification.

Learn about Ventricular Septal Defect (VSD) which is an abnormal opening between the right and left ventricle, and is a common heart defect present at birth.

Learn about diastolic murmurs which are murmurs heard during diastole, between the second heart sound (S2) and the first heart sound (S1).

Learn about Mitral stenosis (MS) which is the narrowing of the heart’s mitral valve such that it cannot open all the way - obstructing blood flow from the left atrium to the left ventricle.

Learn about Aortic regurgitation (AR) which is a condition in which the aortic valve does not close properly, allowing blood to flow in the reverse direction from the aorta back into the left ventricle during diastole.

Learn about continuous murmurs which begin in systole, peak near the second heart sound (S2), and continue into part or all of diastole.

Learn Patent Ductus Arteriosus (PDA) which is a congenital defect where the ductus fails to close in the early weeks of life, resulting in the abnormal transmission of oxygenated blood to flow back to the pulmonary circulation from the aorta.

Learn about arrhythmias which are irregular or abnormal heartbeat. Arrhythmias occur when changes in the electrical impulses cause the heart to beat irregularly, too fast, or too slowly.

Learn about Atrial Fibrillation, the most common chronic arrhythmia. It is characterized by disorganized atrial contraction and electrical activity.

Learn about crackles which can be characterized as abnormal, discontinuous, “rattling” sounds heard best during inspiration in lungs with respiratory disease.

Learn about wheezes, a high-pitched, musical, lung sound heard best during expiration.

Artificial Intelligence (AI) - a practical tool for the clinical workflow.
