What Are the 3 Types of Stress Tests?

Stress tests are medical evaluations that measure how your heart performs under pressure — either through exercise or medication. These tests help detect cardiovascular problems, such as artery blockages, irregular heart rhythms, or general heart function under strain. 

1. Exercise Stress Test (Treadmill Test)

• What it is: You walk on a treadmill or cycle on a stationary bike while your heart rate, blood pressure, and ECG are monitored.
• Purpose: Evaluates how well your heart handles physical activity.
• Ideal for: Detecting blocked arteries, arrhythmias, and assessing cardiovascular endurance.

2. Nuclear Stress Test

• What it is: A radioactive tracer is injected into your bloodstream, and special imaging tracks blood flow before and after exercise or stress medication.
• Purpose: Identifies areas with poor blood flow or damaged heart muscle.
• Ideal for: Diagnosing coronary artery disease and measuring the extent of previous damage.

3. Stress Echocardiogram (Echo Stress Test)

• What it is: Combines ultrasound imaging with stress testing (exercise or medication-induced).
• Purpose: Assesses heart muscle movement and pumping strength.
• Ideal for: Identifying abnormal wall motion or valve problems under stress.

Signs You Need a Stress Test

Recognizing symptoms early can make a major difference. Here are common signs that may suggest you need to undergo a stress test:

• Chest pain or discomfort during activity
• Shortness of breath on exertion
• Irregular heartbeats or palpitations
• Dizziness, fatigue, or poor workout recovery
• A family history of heart disease

If you're noticing any of the above, it's important to consult a healthcare professional. In many cases, smartwatches can help you spot these signs before you experience a major event.

How the WalkerFit M6 Ultra Smartwatch Helps

The WalkerFit M6 Ultra Smartwatch is designed not only for activity tracking, but for real-time health monitoring. Here's how it helps spot early signs that may lead to a recommended stress test:

Heart Rate Monitoring

Continuous tracking alerts you to abnormally high or low resting heart rates — potential warning signs for heart conditions.

Blood Oxygen Monitoring (SpO2)

Low blood oxygen levels during sleep or activity can be a precursor to sleep apnea or poor circulation, both of which affect heart health.

Stress Tracking & HRV (Heart Rate Variability)

The M6 Ultra includes stress level monitoring and HRV data — essential indicators of how your nervous system and heart are responding to physical or emotional strain.

 

Activity & Recovery Monitoring

If the watch notices that your activity levels are dropping or that recovery from workouts is taking longer than usual, it may indicate cardiovascular strain.

Sleep Quality Tracking

Poor sleep and frequent awakenings can increase cardiovascular risk. The M6 Ultra provides detailed sleep data to help identify patterns linked to stress or heart strain.
