The heart has a regular rhythm in which it pumps blood all through the body. It conducts this activity by contracting one part of itself to let blood force out and relaxing another area to let the blood flow in. The rhythm is kept constant using a natural pacemaker which is also known as sinoatrial node.
This node is known to send out electrical impulses which is when the heart beats normally. These electrical signals can be measured and easily tracked using technology, which allows doctors to follow the rhythm of the heart and understand if there are any problems.
How does the ECG test help?
When you go for an ECG test, the impulses of the heart are recorded and printed on a piece of paper. This is called an electrocardiogram and it records the beating rhythm of the heart and with the process of beating, doctors can understand if there are any underlying problems in the heart. ECG is one of the most important and easily available tools to diagnose heart problems. It accurately measures the heart rate, promptness of heart beats and the size and position of chambers in the heart. With the readings of the ECG, doctors can immediately understand the presence of any damage to the heart and with the results, doctors can regulate the heart using pacemakers and medications as well.
Advantages of an ECG test
This test has various advantages for the patient as well as the doctors and hospitals. It is a painless test that is non-invasive, safe and inexpensive as well. The test is easy to perform so doctors can use the test to effectively determine heart problems without any hassles.
The machines are also easily available in the market and they are available in all kinds of medical facilities. You need not visit a major hospital to get these tests done. You can get it from any small medical centre and private physicians as well.
After an ECG
While an ECG test can be accurate and precise, if you have continuous problems of the heart, and it does not show in an ECG, you might get an advanced test done after the right recommendation of your cardiologist. ECG is an initial diagnostic test that must be considered as the first step of diagnosis. If symptoms and problems persist, you must always get further tests done.
An ECG is one of the most effective tools to detect heart problems and helps doctors understand the heart rhythms in the most accurate manner.
