I now have all the essential data. I can see this is a complete TMT (Treadmill Stress Test) report. Pages 3-10 are ECG traces from different stages. I have all the information I need from pages 1 and 2. Let me now provide a thorough, simple explanation.
TMT (Treadmill Stress Test) Report - Rahul Chavhan, 41 Years Male
Hospital: Platina Heart Hospital, Nagpur | Date: May 23, 2026 | Cardiologist: Dr. Pramod Mundra, MD, DM (Cardiology)
š§ Patient Details
| Field | Value |
|---|
| Name | Mr. Rahul Chavhan |
| Age / Sex | 41 years / Male |
| Height | 161 cm |
| Weight | 58 kg |
| Address | Wadi, Nagpur |
What this means: At 58 kg and 161 cm, his BMI is approximately 22.4 - which is in the normal/healthy range (18.5-24.9). He is not overweight.
š What Is This Test? (TMT / Stress Test)
A Treadmill Test (TMT) - also called a Cardiac Stress Test - checks how your heart behaves when it is under physical stress. You walk/run on a treadmill while your heart's electrical activity (ECG) and blood pressure are continuously monitored. The speed and incline increase in stages.
Why it's done: To detect if there is any blockage or reduced blood supply to the heart that only shows up during exertion (not at rest).
š Test Setup
| Field | Value | Explanation |
|---|
| Protocol | Modified Bruce | A standard, widely-used treadmill exercise protocol. "Modified" means it starts more gently - suitable for patients who may not be very fit or have risk factors. |
| Object of Test | IHD Screening | IHD = Ischaemic Heart Disease (blockage in heart arteries). The test was done to screen/check if Rahul has any such blockage. |
| Brief History | IHD Screening | Confirms this was a preventive/screening test, not because of existing symptoms. |
ā ļø Risk Factors
Listed: Male, Hypertension, Age
Simple Explanation:
- Male sex: Men have a higher risk of heart disease than pre-menopausal women.
- Hypertension: High blood pressure (which he seems to have - confirmed by his BP readings during the test). High BP damages artery walls over time and is a major risk factor for heart attacks.
- Age: At 41, he is entering the age window where cardiac risk starts increasing.
š Exercise Stages - Step by Step Data (Page 2 Table)
The test ran through several stages, increasing in speed and effort:
| Stage | Time | Speed | Grade | Heart Rate (bpm) | BP (mmHg) | METs | ST Level |
|---|
| Pre-Test | 0:20 | 0 km/h | 0% | 73 | 120/80 | 1.00 | 0.52 |
| Supine | 0:05 | 0 | 0 | 77 | 120/80 | 1.00 | 0.52 |
| Standing | 0:06 | 0 | 0 | 76 | 120/80 | 1.00 | 0.42 |
| Hyperventilation | 0:07 | 0 | 0 | 75 | 120/80 | 1.00 | 0.29 |
| Wait for Exercise | 0:08 | 0 | 0 | 77 | 120/80 | 1.00 | -- |
| Exercise Stage 1 | 3:00 | 2.7 km/h | 0% | 88 | 120/80 | 2.28 | 0.68 |
| Exercise Stage 2 | 3:00 | 2.7 km/h | 5% | 91 | 140/80 | 3.44 | 0.77 |
| Exercise Stage 3 | 3:00 | 2.7 km/h | 10% | 100 | 150/80 | 4.60 | -0.03 |
| Exercise Stage 4 | 3:00 | 4.0 km/h | 12% | 111 | 160/80 | 7.01 | -0.29 |
| Peak Exercise | 0:01 | 5.5 km/h | 14% | 111 | 160/80 | 10.21 | -0.29 |
| Recovery 1 | 1:00 | 0 | 0 | 97 | 160/80 | 1.00 | 0.29 |
| Recovery 3 | 3:00 | 0 | 0 | 77 | 160/80 | 1.00 | 0.48 |
Explaining Each Column:
Heart Rate (HR) in bpm: How fast his heart was beating. At rest it was 73 bpm (very normal). At peak exercise it reached 111 bpm.
- His Maximum Predicted Heart Rate = 220 - age = 220 - 41 = 179 bpm
- He achieved 112 bpm = 62.57% of 179 bpm
- Ideally, for a conclusive negative test you want to reach 85% of maximum (about 152 bpm). He did not reach 85% because the test was stopped early due to lower limb pain (not heart symptoms), but the cardiologist still interpreted it as negative.
Blood Pressure (BP): Started at 120/80 (perfectly normal). Rose to 160/80 at peak exercise.
- A rise in BP during exercise is completely expected and normal.
- His resting BP of 120/80 is at the upper border of normal / early Stage 1 hypertension.
METs (Metabolic Equivalents): A measure of how much energy/effort is being expended.
- 1 MET = sitting quietly at rest
- He reached 10.21 METs at peak exercise - this is a good functional capacity. Anything above 10 METs is generally considered excellent cardiac fitness.
ST Level (mm): This is the most important measurement in a stress test. The ST segment on the ECG represents blood flow to the heart muscle.
- ST depression ā„ 1 mm during exercise = sign of possible ischemia (inadequate blood supply to heart)
- His ST changes were very minor: small positive values at rest (normal variant), small negative values (-0.29 mm) at peak - well below the 1 mm threshold for concern
š Why Was the Test Stopped?
Reason for Termination: LOWER LIMB PAIN
He stopped because his legs got tired/painful - NOT because of chest pain, breathlessness, or any heart-related symptom. This is a non-cardiac reason for stopping, which is a reassuring finding.
š Key Summary Numbers
| Parameter | Value | What It Means |
|---|
| Total Exercise Time | 12 minutes 1 second | Very good duration - shows he has decent physical endurance |
| Max Heart Rate | 112 bpm (62.57% of 179 bpm) | Did not reach target 85%, but test still valid as negative |
| Max Workload | 10.21 METs | Excellent - above 10 METs = good heart reserve |
| Max BP | 160/80 mmHg | Normal exercise response |
| Distance Covered | 0.61 km | -- |
| Double Product | 17,920 | Heart Rate Ć Systolic BP at peak = 111 Ć 160 = 17,760 (close match). This number reflects peak cardiac work. Values > 25,000 would be excellent; his is moderate-good. |
š« ECG Findings - The Heart Tracings (Pages 3-10)
Pages 3 onwards show the actual ECG recordings at different stages.
Pre-Test ECG (Page 3 - Linked Median Report)
- Stage: Pre-Test | HR: 73 bpm | BP: 120/80 | METs: 1.00
- Shows the heart's electrical pattern before any exercise.
Exercise Stage 1 ECG (Page 4)
- HR: 88 bpm | BP: 120/80 | METs: 3.44 | Speed: 2.7 km/h
- Heart rate appropriately rising. No concerning ST changes.
The subsequent pages (Pages 5-10) show ECG traces at each subsequent stage of exercise - they represent the continuous monitoring throughout the test.
Key ECG Finding noted on the report: "NSR, LVH"
- NSR = Normal Sinus Rhythm - The heart's natural pacemaker (sinus node) is in control. The heartbeat is regular and originates from the correct place. This is the ideal, normal finding.
- LVH = Left Ventricular Hypertrophy - The left ventricle (the main pumping chamber) is slightly thickened/enlarged. This is NOT a heart attack finding. It is commonly seen in people with hypertension - when the heart has to pump against high blood pressure for years, its walls thicken, just like a bicep muscle grows with regular exercise. It confirms he likely has had hypertension for some time.
ā
Final Impression (The Doctor's Reading)
| Phase | Finding |
|---|
| Pre-Test | NSR (Normal Sinus Rhythm) + LVH (Left Ventricular Hypertrophy) |
| Peak Exercise | NO SIGNIFICANT ST-T CHANGES |
| Recovery | UNEVENTFUL |
What "No significant ST-T changes" means: During peak physical effort, the heart's blood supply remained adequate. No signs of ischemia (blockage) were detected.
What "Uneventful recovery" means: After the exercise stopped, the heart returned to its baseline normally without any abnormal rhythms, extra beats, or BP problems.
š CONCLUSION (The Most Important Line)
"TMT IS NEGATIVE FOR INDUCIBLE ISCHAEMIA AT 12:02 MINUTES OF EXERCISE IN MODIFIED BRUCE PROTOCOL."
In plain language: The treadmill stress test is NEGATIVE - meaning no evidence of blocked or reduced blood supply to the heart was found during exercise. Rahul does NOT appear to have significant coronary artery disease at this time.
š Overall Summary for Rahul
| Finding | Status | What To Do |
|---|
| Heart blockage (IHD) | ā Not detected - Negative TMT | Good news - no major blockages found |
| Heart rhythm | ā
Normal (NSR) | No action needed |
| LVH (thickened heart wall) | ā ļø Present | Likely due to hypertension - needs BP control |
| Blood Pressure at rest | ā ļø 120/80 (borderline) | Monitor, lifestyle changes |
| Exercise capacity | ā
Good (10.21 METs, 12 min) | Maintain regular physical activity |
| ST changes during exercise | ā
No significant changes | Reassuring |
š” Key Takeaways in Simple Words
- Good news: Your heart stress test came back normal - no blockages detected during exercise.
- Watch your blood pressure: The LVH on ECG means high BP has been stressing your heart for some time. Controlling BP is the #1 priority.
- Leg pain, not heart pain: The test stopped because your legs got tired, not because your heart struggled - another positive sign.
- Good fitness level: Completing 12 minutes and reaching 10+ METs shows decent heart and body fitness.
- Follow up regularly: With hypertension as a risk factor, annual cardiac checkups are advisable.
