❤️ “T” Wave in ECG

Let’s understand this in a very simple way.

What is ECG?
ECG (Electrocardiogram) records the electrical activity of the heart.

👉 Different waves represent different heart activities.

What does the “T” wave show?

✅ Correct Answer: (b) Ventricular repolarization

What is repolarization?
Repolarization means the heart muscle is:

• Relaxing
• Returning to resting state
• Preparing for next heartbeat

👉 So, T wave represents recovery of ventricles after contraction.

Easy ECG understanding:

• P wave → Atrial depolarization
• QRS complex → Ventricular depolarization
• T wave → Ventricular repolarization

Why other options are not correct?

• (a) Ventricular depolarization → ❌ QRS complex
• (c) Atrial depolarization → ❌ P wave
• (d) Atrial repolarization → ❌ Hidden inside QRS complex

Simple Exam Trick:
T = “Time to relax” → Ventricular repolarization

📌 Disclaimer: For exam preparation only. Follow clinical ECG interpretation guidelines in practice.
