Your heart doesn’t come with a warning light, but it does send signals. The tricky part? Decoding them before something serious shows up. That’s where heart tests come in. Whether your doctor just told you to do one or you’re simply curious about your heart health, this guide breaks it all down without overwhelming you.
We’ll walk through the types of heart tests, what they measure, what your reports actually mean, and how to have better conversations with your doctor about the results.
What Are Heart Tests?
Heart tests are diagnostic tools that evaluate how well your heart is functioning. They help detect early signs of heart disease, monitor existing conditions, or clear doubts if you have chest pain, shortness of breath, or other suspicious symptoms.
There are non-invasive options like ECGs and blood tests, and more advanced scans like MRIs or CTAs. Some are done during rest, others during physical stress. The key is knowing which one tells you what.
10 Common Heart Tests You Should Know About
Understanding the different types and common heart tests can help you feel more in control of your care. Each test offers a different window into your heart’s health, whether it's your rhythm, structure, blood flow, or risk of disease. Some tests are used to confirm diagnoses, others to screen for risk factors even before symptoms appear. These are the most commonly recommended tests to check heart health, each offering a different insight into your heart’s condition. If you’re looking at heart checkup packages, understanding what each test is for can help you make better choices.
1. Electrocardiogram (ECG or EKG)
This quick test records your heart’s electrical activity. It can detect irregular rhythms (arrhythmias), signs of a previous or current heart attack, and abnormalities in heart size.
In the heart ECG report, you’ll see:
- Heart Rate (BPM): Normal is 60-100 bpm.
- P wave, QRS complex, T wave: These represent various phases of your heartbeat.
- PR/QT intervals: Measure timing.
- ST-segment: Elevation or depression can signal a heart attack.

2. Echocardiogram (ECHO)
An echocardiogram test is an ultrasound-based test that gives a real-time image of your heart. It checks heart valves, wall motion, and pumping efficiency.
An echo report for the heart typically includes:
- Ejection Fraction (EF): How much blood your heart pumps with each beat. Normal is 55-70%.
- Valve Function: Whether they open and close properly.
- Wall Motion Abnormalities: Can indicate areas affected by a past heart attack.
3. Transesophageal Echocardiography (TEE)
This is similar to an echo, but more detailed. A probe is inserted through the esophagus, which lies closer to the heart. It gives sharper images, especially for complex valve or clot detection.
What You’ll See in the Report?
- Enhanced views of valves, clots, or infections.
- Often used for pre-surgery evaluation or suspected endocarditis.
Especially useful when surface echoes aren’t clear enough. A heart TEE test may be ordered before surgery or to confirm endocarditis.
4. Magnetic Resonance Imaging (MRI)
A heart MRI scan creates highly detailed images using magnets and radio waves. It’s great for spotting tissue damage, heart muscle scarring, and congenital issues.
What You’ll See in the Report?
- Size and structure of heart chambers
- Presence of fibrosis or inflammation
- Heart function (EF included)
5. Coronary Computed Tomography Angiogram (CCTA)
A CCTA test (Coronary CT Angiography), a non-invasive way to visualize coronary arteries and check for blockages or narrowing.
Heart scan report will show:
- Any plaque buildup or narrowing of arteries
- Calcium scores may be mentioned
- Recommendations for further tests, like angiography if needed
6. Coronary Artery Calcium (CAC) Test
What does it measure?
This specialized CT scan detects calcium deposits in the coronary arteries.
What You’ll See in the Report?
- Calcium Score: Ranges from 0 (no calcium) to 400+ (extensive plaque buildup)
- Risk category based on score
If your heart blood tests include a high CAC score, talk to a cardiologist in Bangalore today.
7. Chest X-ray
What does it measure?
Though basic, a heart X-ray can show the size and shape of the heart, fluid in the lungs, and some lung diseases.
Your heart X-ray or heart X-ray report helps check:
- Enlarged heart
- Signs of heart failure
- Abnormalities in surrounding structures
8. CT Scan
What does it measure?
A CT can give cross-sectional images of the heart and blood vessels.
What You’ll See in the Report?
- Blockages, tumors, or structural defects
- Often paired with contrast dye for better visuals
9. Stress Test (Treadmill or Pharmacologic)
What does it measure?
It checks how your heart performs under stress (physical or medication-induced).
What You’ll See in the Report?
- Heart rate response
- Blood pressure response
- ECG changes
- Symptoms during the test
Useful when your normal heart rate changes during activity or you report exercise intolerance.
10. Blood Tests
These are part of routine heart-related blood tests or full heart blood tests panels.
Cholesterol Levels
This test measures the levels of different fats (lipids) in your blood, which help assess your heart disease risk.
- LDL (Low-Density Lipoprotein): Often called "bad" cholesterol. High levels can lead to plaque buildup in arteries, increasing heart attack and stroke risk.
- HDL (High-Density Lipoprotein): The "good" cholesterol. It helps remove LDL from your bloodstream. Higher HDL levels are generally protective.
- Triglycerides: A type of fat your body uses for energy. Elevated triglycerides, especially alongside high LDL or low HDL, raise your risk for heart disease.
- Total Cholesterol: A combined number that gives a quick view, but breaking down each component gives a clearer picture.
High-Sensitivity C-Reactive Protein (hs-CRP)
C-Reactive Protein test checks for inflammation in your body, especially in the blood vessels.
Inflammation plays a key role in atherosclerosis (plaque buildup in arteries). Even if your cholesterol is normal, a high hs-CRP may signal increased risk for heart disease or stroke.
Lipoprotein(a)
Also known as Lp(a), this is a special type of LDL cholesterol that’s mostly inherited. High Lp(a) levels don’t usually respond to diet or exercise and can silently contribute to plaque buildup.
It’s considered an independent risk factor, meaning you could have normal cholesterol levels and still be at risk because of elevated Lp(a).
How to Understand a Heart Test Report
Reading a heart test report can feel like decoding a foreign language. But each number, wave, and abbreviation is trying to tell you something important. Here's how to make sense of the key parts:
Heart Rate
This tells you how fast your heart is beating. Normal is 60-100 bpm. If it’s too high (tachycardia) or too low (bradycardia), it could point to underlying issues. A heart rate monitor can help track patterns over time.
Ejection Fraction (EF)
This measures the percentage of blood your heart pumps out with each beat. The normal ejection fraction is 55-70%. Lower values might suggest heart failure, while values that are too high may point to hypertrophic conditions.
Cholesterol Levels
- LDL (bad): Ideally under 100 mg/dL. High levels increase plaque buildup.
- HDL (good): Over 40 mg/dL for men and 50 mg/dL for women. Higher is better.
- Triglycerides: Under 150 mg/dL. Elevated levels can increase heart disease risk.
These values are typically part of heart-related tests done during routine evaluations or checkups.
Blood Pressure
Reported as systolic/diastolic (e.g., 120/80 mm Hg). High blood pressure is a major risk factor for heart disease, stroke, and kidney issues. Normal blood pressure helps reduce these risks significantly.
Calcium Score
This is the result of a CAC test for the heart, indicating how much calcium has built up in your coronary arteries. A score of 0 means no detectable plaque. Higher scores suggest higher risk and may call for treatment or lifestyle changes.
How to Discuss Your Results with Your Doctor
So, you've got your heart test report in hand. Now what? Here’s how to make the most of that consultation.
Ask for Clarification
Don’t nod along if you don’t understand something. If your report says “abnormal ECG” or mentions certain ECG measures, ask your doctor to break it down:
- What does this number mean?
- Is it in the normal range?
- Is this something urgent or manageable?
That’s literally your doctor’s job — explaining what these readings say about your heart’s function.
Inquire About Next Steps
Once you know what the report says, the next question is: What now?
- Will you need another test – like an Echo, TMT, or CCTA?
- Do you need to start medication?
- Is this pointing toward a potential heart emergency?
Don't leave the room without a clear roadmap.
Be Proactive
Use the report as a starting point, not a dead-end. If your cholesterol is borderline, or if an ECG measure showed mild arrhythmia, take action:
- Clean up your diet
- Start walking 30 minutes a day
- Prioritize sleep and stress management
Even small changes help your heart perform better over time.
When Should You Get a Heart Test?
- You have risk factors: diabetes, high BP, smoking, or a family history
- You’re over 40 and haven’t had a recent heart health test. This is usually the age when people wonder at what age they should see a cardiologist.
- You feel chest discomfort, fatigue, breathlessness, palpitations
- You're planning to start a high-intensity workout
