Diastolic Dysfunction evaluation on Echocardiography

Watch above video to understand diastolic Dysfunction

Diastolic Dysfunction on Echo:

Diastolic dysfunction refers to the heart's inability to relax and fill properly during diastole. Echo findings:

Grading of Diastolic Dysfunction:

1. *Grade 1 (Mild)*: Abnormal relaxation, E/A ratio < 0.8

2. *Grade 2 (Moderate)*: Pseudonormal filling, E/A ratio 0.8-1.5

3. *Grade 3 (Severe)*: Restrictive filling, E/A ratio > 2

Echo Parameters:

1. *E/A Ratio*: Early diastolic filling velocity (E) to late diastolic filling velocity (A) ratio

2. *E-wave Deceleration Time (DT)*: Time for E-wave to decrease from peak to baseline

3. *Isovolumic Relaxation Time (IVRT)*: Time from aortic valve closure to mitral valve opening

4. *Tissue Doppler Imaging (TDI)*: Measures myocardial velocities, helping to assess diastolic function

Clinical Significance:

Diastolic dysfunction can lead to:

1. Heart failure with preserved ejection fraction (HFpEF)

2. Increased risk of cardiovascular events

3. Decreased exercise tolerance

Accurate diagnosis and grading of diastolic dysfunction on echo can guide management strategies and improve patient outcomes.

Approach to Supraventricular Tachycardia - SVT

I would like to share with you about SVTs, or supraventricular tachycardia, today. I'll be focusing on the pathophysiology, ECG features, and the management of SVT today. So this is a brief outline of the lecture today. I will be going through the definition of SVTs, followed by a brief classification of tachyarrhythmias, the pathophysiology behind it all, ECG features, and management principles of SVTs. I will round off the lecture with a clinical scenario related to the topic. This lecture is meant to be a basic introduction to SVTs, and is by all means not exhaustive. So without further ado, let us begin. Supraventricular tachycardias are defined as narrow complex tachycardias where the point of stimulation arises from above the bundle branches. There are many types of SVTs, as will be shown in the next slide, and some are more common than the others. However, in our local context, it is used interchangeably with proximal supraventricular tachycardias, which make up a...

Learn Echocardiography | Standard Protocol for Performing Comprehensive Echocardiogram | Explained with Images and Videos

If you are just starting to learn echocardiography, you will find that learning the full echo examination protocol will be immensely useful. The full protocol will provide a solid foundation for your career in echo. I personally found that once I could execute the standard protocol flawlessly, I was able to add and refine additional echo scanning skills while deepening my understanding of the purpose of each echo image. The echo protocol illustrated in this article is the same one we currently use for all our patients in the hospital and meets or exceeds the standards of American Society of Echocardiography (ASE) for an adult echocardiography examination. The protocol presented here is meant as a guideline and does not cover every aspect (such as off axis views) of an echo examination. Also other hospitals will probably have slight variations of this protocol depending on the lab's needs, which is normal. This article's main purpose is to provide a solid foundation for ...
