Echo Cardiography

Why Echo Cardiography?

Patient Instructions

Echocardiography is a non-invasive, safe, and painless procedure. Our technologist will keep a hand-held wand on your chest to generate images of the heart's valves and chambers during the test. An Echo Cardiography helps your doctor to evaluate the:
  • Pumping action of your heart
  • Functioning of the valves
  • The direction of blood flow in the heart
  • Thickness and size of the chambers
  • Damaged and scarred heart muscles and tissues

An Echo Cardiography plays a crucial role in determining the health of your heart, especially after a heart attack. You may require one if you have the following symptoms:
  • Shortness of breath
  • Leg swelling
  • Heart murmurs
  • Irregular heartbeat
  • Abnormal blood pressure
  • Congenital heart defects

A regular Echo does not require any specific instructions. However, you must follow these preparations for other types of Echo tests:

Transthoracic echocardiography -

  • You can eat and drink as usual before the test
  • Take your medication before the procedure

Treadmill Test Or Exercise ECG

Why Treadmill tests?

Patient Instructions

A treadmill test allows your cardiologist to assess your heart function when subjected to actions like walking, running, or jogging. The test requires you to walk on a treadmill or use a stationary cycle at various speeds, steadily increasing resistance. You will be connected to ECG sensors that continuously record your heart rhythm. At Krishna Scans, we offer tests with:
  • PC-Based cardiac workstation combining resting and exercise ECG
  • Standard and user-programmable treadmill protocols
  • Simultaneous acquisition and display of 12 lead raw ECG
  • Risk predicting Duke Treadmill score
  • User-configured multiple displays and reports format
  • Heavy-duty treadmill

An exercise stress test determines how well your heart functions and responds when it is working hard. Our cardiologist will prescribe a treadmill test for the following:
  • Detect coronary heart diseases
  • Detect lead-offs and Arrhythmias
  • Identify abnormal heart rhythms
  • Determine safe exercise levels to follow after a heart attack or heart surgery.

Before the treadmill test, you must consult our cardiologist for a thorough examination. Here are some instructions to follow:
  • Inform your doctor about your medical history
  • Bring your inhaler for the test, if you are using one

  • Avoid all caffeinated food for 12 hours before the test
  • Avoid eating or drinking anything for 4 hours before the test

Why ECGs?

Patient Instructions

ECG or Electrocardiogram interprets your heart's electrical impulses into line tracings or waves on a graph sheet. 

Our cardiologists interpret these lines to assess your heart's rhythm and electrical activity. 

An ECG is often prescribed with other diagnostic tests to diagnose and monitor your cardiac health.
An ECG is one of the basic diagnostic tests recommended by most cardiologists and other specialists if they suspect that you have a cardiac problem. An ECG will help your doctor to detect:
  • Cardiomyopathy or enlargement and thickening of the heart muscles.
  • Heart attack or blocked blood supply to the heart.
  • Coronary heart disease where the blood supply to the heart is blocked or interrupted by the thickening of the arteries.
  • Arrhythmia where the heart beats irregularly, slowly, or quickly.
Book an Appointment
An ECG test does not require any special preparations. However, it is advisable to follow these instructions:
  • Avoid taking meals and having caffeinated drinks two hours before the test, as it may affect your heart rhythm.
  • Avoid fasting for long hours before the test.
  • Remove your jewellery, watch, and other metal objects before the exam.
  • Avoid using any lotions and moisturisers as the electrodes may not stick properly.
  • Inform your doctor about the prescribed and non-prescribed medications you are taking.

1. What are the risks associated with an Echo Cardiograph test?
None at all. An Echo Cardiograph is a safe procedure with no risks or side effects.
2. Will I require these cardiac tests if I have an existing heart condition?
A heart scan will not be necessary for those who've undergone coronary bypass surgery or if they have a heart stent. It is also not necessary for those with coronary disease. People with such cardiac conditions should regularly consult a cardiologist.
3. What does a treadmill test indicate?
A treadmill test can reveal problems with the blood flow to the heart. An abnormal treadmill test result for people with underlying symptoms indicates a higher risk of coronary artery disease. The symptoms include shortness of breath and chest pain during activity. When an older, obese person experiences the same symptoms, it also indicates coronary artery disease.
4. What happens during an ECG?

Our technician will attach small sensors to various parts of your chest, arms, and legs. These sensors are sticky pads connected by wires to an ECG recording machine, recording your heart rhythms. There are no special instructions to follow before an ECG, and you may have your meals beforehand.

Your chest will need to be shaved and cleaned before the procedure. You will also have to remove your upper garments and change into a hospital gown for the exam.

5. How long will an ECG test take?
An ECG will last only a few minutes, and you will be able to return home as soon as the procedure is over.
6. When can I expect my ECG results?
You will receive a report from our doctor that will describe the heart anatomy, movements, and any anomalies identified during the test. You will receive the reports within a few days or maybe a few weeks depending on the nature of the test.
