ECG vs. Echocardiogram: Which Test Do You Need?

---

Introduction

When it comes to checking your heart’s health, two tests are commonly requested: the ECG (electrocardiogram) and the echocardiogram.

Although their names sound similar, they serve different purposes. Many patients in Manila ask, “Which test do I really need?” This article breaks down the differences, what each test shows, and when your doctor recommends them.

What is an ECG?

An ECG records the heart’s electrical activity. It shows:

• Heart rate (how fast your heart beats)
• Rhythm (regular or irregular)
• Signs of past or ongoing heart attacks
• Abnormalities in heart conduction

👉 Quick facts:

• Duration: 5–10 minutes
• Cost in Manila: ₱300–₱2,500
• Best for: Detecting irregular rhythms and acute heart problems

What is an Echocardiogram?

An echocardiogram (echo) uses ultrasound waves to create moving images of the heart. It shows:

• Heart structure (chambers and valves)
• Pumping strength (ejection fraction)
• Blood flow inside the heart
• Valve leaks or narrowing

👉 Quick facts:

• Duration: 30–45 minutes
• Cost in Manila: ₱3,000–₱8,000
• Best for: Assessing structural and functional heart problems

Key Differences Between ECG and Echocardiogram

Feature	ECG	Echocardiogram
What it shows	Electrical signals, rhythm	Images of heart structure
Duration	10–15 mins	40–50 mins
Cost (Manila)	₱400–₱2,000	₱3,000–₱8,000
Main use	Detect arrhythmias, heart attack signs	Assess valves, pumping strength
Pain/Discomfort	None	None (gel applied on chest)
Availability	Almost all hospitals/clinics	Larger hospitals & cardiac centers

When Do You Need an ECG?

Doctors recommend ECG if you have:

• Sudden chest pain or tightness
• Palpitations or irregular heartbeat
• Fainting or dizziness
• Hypertension or diabetes (as part of regular checkups)
• Pre-surgical evaluation

---

When Do You Need an Echocardiogram?

Doctors recommend echo if they suspect:

• Valve problems (leaky or narrow valves)
• Heart failure or weak pumping
• Congenital heart disease
• Enlargement of heart chambers
• High blood pressure affecting the heart muscle

---

Can You Need Both Tests?

Yes. In many cases, doctors order both tests because they complement each other:

• ECG shows the electrical activity of the heart.
• Echocardiogram shows the physical structure and functions.

For example, if your ECG shows irregularities, an echo may be needed. This test determines if the structure of the heart is affected.

Cost Comparison in the Philippines

• ECG: ₱300–₱2,500
• Echocardiogram: ₱3,000–₱8,000
• Package of both (in some cardiac centers): ₱4,000–₱10,000

Some insurance providers cover both tests if prescribed by a cardiologist.

Summary

Both ECG and echocardiogram are vital in checking heart health, but they answer different questions:

• ECG → Is the heartbeat normal and healthy?
• Echo → Is the heart structure and pumping normal?

If you experience chest pain, shortness of breath, or irregular heartbeat, your doctor orders one test. They can also order both tests to get the full picture. Early testing saves lives—don’t wait until symptoms worsen before consulting your doctor.
