Holter, TMT, ECG

Jump to Tests


Regular electrocardiograms (ECG) create results of the heart’s activity at one point in time. But abnormal heart rhythms and cardiac symptoms may come and go. When ECG gives conclusive indications of cardiovascular illnesses, a battery-operated portable device (Holter monitor) is attached to assess the patient’s heart status. It measures the heart’s activity for 24 to 48 hours or longer as the patient completes his everyday activities, including night sleep. Holter monitoring is profoundly valuable for cardiologists to make precise analyses.

 Patients are asked to wear a Holter monitor if they have fast, slow, or irregular heartbeats called arrhythmias.

TMT (Treadmill Test) :

Sometimes, ECG signifies normal results in a resting position. During physical activity, heart diseases can surface, making it impossible for a person to function normally. For that reason, a treadmill test is done. A TMT is helpful in determining the heart’s function by indirectly measuring arterial blood flow to the heart. During the test, blood flow to the heart is measured when the patient is resting and when he/she is exercising at different levels of intensity. 

What happens during TMT?

Electrodes are connected to the patient’s chest. The first heart rate and blood pressure measurement is taken when the patient is at rest. Next, measurements are taken while the patient walks on the treadmill at a slow to mild speed. Gradually, speed is increased as per the safe protocol and the patient’s endurance until a certain heart rate is reached. If the readings are abnormal and the patient is uncomfortable, the test will be stopped before it's done.

ECG (Electrocardiography):

ECG is a device used to record the electrical signals in the heart each time it beats with the help of electrodes attached to the skin. Usually, ECG is recommended for suspecting a heart attack. It is also helpful in learning about previous heart attacks, damage caused to the heart, and the extent of that damage.

ECG is a valuable examination for monitoring heart rate and heart rhythm. An ECG test can easily detect arrhythmia or irregular heartbeat due to issues in the heart's electrical system. Also, it measures a speedy heart rate (tachycardia), a slow heart rate (bradycardia). 

Instructions for TMT:
  • Wear comfortable clothes that fit you.
  • Wear well-fitted walking or jogging shoes.
  • Avoid eating 3 to 4 hours before the test.
  • If you take heart medications or others, please discuss this with the doctor beforehand
