What is ECG?
ECG (electrocardiogram) is a test that measures the electrical activity of the heart. The heart is a muscular organ that beats in rhythm to pump the blood through the body. The signals that make the heart's muscle fibres contract come from the sinoatrial node, which is the natural pacemaker of the heart. In an ECG test, the electrical impulses made while the heart is beating are recorded and usually shown on a piece of paper. This is known as an electrocardiogram, and records any problems with the heart's rhythm, and the conduction of the heart beat through the heart which may be affected by underlying heart disease.
WHY ECG AT STAR?
The PageWriter Trim III cardiograph represents the ultimate in compact, cost-effective cardiograph solutions from Philips. More than simply an easily transportable and interpretive ECG system, the PageWriter Trim III combines ease-of-use features with a high-resolution full-color display and exceptional flexibility to meet the needs of fast-paced clinical environments.
No matter which PageWriter Trim is right for your clinical setting, you can count on the Philips 12-lead ECG report. Patient signals are immediately converted digitally at the Patient Interface Module to provide the highest quality input to the Philips 12-Lead Algorithm. This groundbreaking algorithm, available in all three PageWriter Trim models, sets a new standard in automated interpretation. So you can make clinical decisions with confidence.
Two-dimensional echocardiography can provide excellent images of the heart, paracardiac structures, and the great vessels. During a standard echo, the sound waves are directed to the heart from a small hand-held device called a transducer, which sends and receives signals. Heart walls and valves reflect part of the sound waves back to the transducer to produce pictures of the heart. These images appear in black and white and in color on a TV screen. They're selectively recorded on videotape and special paper, and reviewed and interpreted by a cardiologist (heart specialist).
The Vivid 7 Dimension system is a PC based, software, raw data ultrasound platform that continues to evolve and improve year after year. Annual breakthroughs renew the platform with cutting edge software and hardware. Building on these annual breakthroughs, the Vivid 7 Dimension delivers more real-time 4D imaging capabilities than ever before. Multi-dimensional imaging formats, real-time, un-gated, un-spliced 4D imaging and real-time 4D full volume imaging in an easy to use package, helps clinicians take 4D imaging out of the research lab and into their everyday clinical routine. The Vivid 7 Dimension’06 now delivers faster acquisitions, improved image quality, more cardiovascular information, more quantified analyses, easier reporting. It also improves every dimension of your workflow.
Q. How is the test carried out?
A stress test or treadmill test or exercise records the heart's electrical activity (rate and rhythm) during exercise.
- Prior to the test electrodes will be placed on the chest (same as ECG) and patient is hooked up to equipment to monitor the heart
- Prior to the test you may be asked to breath rapidly hyperventilate) for a while
- The patient will be asked to walk on a motorised treadmill
- The speed and inclination of the treadmill will be gradually increased
- The doctor will be looking for changes in ECG pattern, will check Blood Pressure in between and will be enquiring about any symptoms that patient may experience
- The patient may be on treadmill for up to 15 minutes, depending upon his level of exercise, recovery and cardiovascular condiovascular conditioning
- The test will be stopped if the patient becomes too tired, has any symptoms such as chest pain
Q. What happens after the test is done?
After the test patient will be asked to sit or lie down till heart and blood pressure recovers to baseline. The stress test doctor will then evaluate the data collected through the test and make the necessary recommendations
Q. How long does a normal stress test take?
The total time required for the test will be about 30 minutes.
Q. Is there any risk in taking the test?
There is very little risk in taking the test in healthy person - no more than if a person walks fats or jogs up a big hill. During the test the cardiologist and a technician are always present.
Q. Why is a stress test done?
To find out:
- How hard the heart can work before symptoms develop.
- How quickly the heart recovers after exercise.
- The patients overall level of cardiovascular conditioning.
Q. Is it necessary to take a prior appointment?
Prior appointment will save considerable time on the day of test.
|1||Stress Echo||Prior Appointment preferred. Bring old records. 4hrs. Fasting required. Stop Betablocker drugs for 48hrs. before the test (alternative drug can be taken for BP or heart as advised by referring consultant). Male patients must shave off the chest if require.|
|2||TMT||Patient should be fasting 4 hrs. before the test. Stop beta blocker 48 hours before the study, shave chest if hairy and bring prior records..|
