Electrocardiography (ECG) is the tool for diagnosing the assessing of muscular and electrical functions of the heart. In this process, electrodes are placed on the skin so as to record the normal working conditions of the heart.
These type of electrodes usually detects the tiny form of changes in the electrical path that arises from heart muscles in the electrophysiologic patterns of the depolarizing during each heartbeat.
The ECG records the rhythm of the heart and also the activity of a moving strip of a paper or even a line that is present on the screen. ECG experts or doctors can read as well as interpret the dips and the peaks on the paper or on the screen.
ECG test is mainly used to diagnosis
- A Heart attack.
- Blood coagulation.
- Abnormal rhythms of the heart.
- Enlargement of the one side of the heart.
Types of ECG Test
There are three main kinds of ECG’s
Resting kind of ECG: This type of ECG’s is used to examine the functioning of the heart in the rest position. While performing this test patient is asked to relax and heartbeat is recorded.
Exercise kind of ECG: This type of ECG’s is used to examine the changes in heart functioning during stress or exercise. In this test, a patient is asked to run or walk on the treadmill or a cycle while the heartbeat is getting recorded.
24-hour kind of ECG: sometimes it is said to be helpful to monitor the heartbeat throughout the day, where the person will be asked to wear electrocardiograph machine. The recordings of the machine are read by the doctor.
Medical Uses of ECG
The goal to perform this electrocardiography is to obtain the information concerning the structure and also the functions of the heart. The medical uses of such information are said to be varied and also generally relates to having a need for the knowledge of the structure or its function. Some of the indications to perform electrocardiography includes:
- Fainting or even collapsing.
- Biotelemetry of the patient.
- The testing of Cardiac stress.
- Finding the structural heart diseases.
- A suspected form of pulmonary embolism.
- Monitoring the effects of heart medication.
- A perceived form of cardiac dysrhythmias.
- A suspected form of myocardial infarction or heart attack.
- Assessing the severity of the abnormalities in the electrolyte.
- The monitoring of the form of anesthesia that is involved.
- CTA- Computed tomography angiography and also the MRA- Magnetic resonance angiography of heart
- The screening of Hypertrophic cardiomyopathy in the adolescents as a part of the sports out of the concern for a sudden cardiac death.
