Myocardial Performance Index (Tei Index) – An Interesting One

The Tei Index, introduced by Dr. Chuwa Tei, is a Doppler-derived, noninvasive parameter that evaluates global ventricular performance, integrating both systolic and diastolic functions into a single measure.

How It’s Measured:
⬜ Acquired using pulsed and continuous wave Doppler from:
• Mitral inflow (Apical 4-Chamber view)
• Left ventricular outflow (Apical 5-Chamber view)

⬜ Key intervals measured:
a. IVCT – Isovolumetric Contraction Time
b. IVRT – Isovolumetric Relaxation Time
c. ET – Ejection Time

Formula:
👉 Tei Index = (IVCT + IVRT) / ET
or
👉 Tei Index = (a - b) / b
where:

a = time from mitral valve closure to opening

b = aortic ejection time

Normal Values:

LV Tei Index: ≤ 0.40

RV Tei Index: ≤ 0.43

Interpretation:
🔵 Higher Tei Index → Impaired ventricular function
🔵 Detects early ventricular dysfunction, even when LVEF appears normal

Clinical Significance:

Useful in assessing cardiomyopathies, heart failure, congenital heart disease, and post-transplant monitoring

Applicable in both pediatric and adult cardiology

Wide QRS Tachycardia: Key Players

1. Ventricular Tachycardia (VT)
2. SVT with aberrant conduction
3. SVT featuring pre-excitation (WPW)
4. SVT on an abnormal ECG baseline
5. SVT influenced by hyperkalemia
6. The beat of Ventricular pacing

What is a Myocardial Infarction (Heart Attack)? ❤️

🛑 Blood flow to the heart is blocked.
🦠 Caused by plaque buildup in coronary arteries.
📋 Symptoms:
💔 Chest pain or discomfort
➡️ Pain radiating to shoulder, arm, back, neck, or jaw
😤 Shortness of breath
💦 Sweating
🤢 Nausea
😵 Lightheadedness
🚑 Requires immediate medical attention to minimize damage and improve survival.

🩺 Cardiovascular Artery Imaging: A Stress-Free Experience 🩺

Understanding the importance of precise and clear diagnostic imaging for cardiovascular arteries, we've designed a process to ensure our patients feel comfortable and stress-free during their examination:

Device Check:

We'll guide you through a check of the device beforehand.
Comfort Setup:

You'll be seated comfortably in a chair.
All lights will be turned on in the imaging room.
Air conditioning will be adjusted to avoid any tremor.
Familiarization:

The device will be turned on without taking pictures initially, allowing you to become accustomed to the sound and operation.
Reassurance:

We'll take our time to reassure you and explain each step before we start the actual procedures.
Precision and Safety:

We use the lowest dose of radiation.
A precise amount of dye (70 Fluorete 5 Hoss Field and 160) is used to push the sound button when the heart rate drops from 80 to 65.
✨ With this approach, we aim to deliver the best results with minimal stress.

Your comfort and health are our top priorities. Reach out to us to learn more about our imaging process and schedule your stress-free cardiovascular artery check-up!
