What is an electrocardiograph?
Electrocardiography, also known as A ECG or ECG, is a medical diagnostic technique that records heart electrical pulses. Recorded impulses are pulses that precede the contractions of the heart muscle. This painless procedure is often used to diagnose coronary artery diseases, heart rhythm disorders and inflammation of the protective heart membrane. Electrocardiography can also detect the presence of a past heart attack and may indicate whether one has one at that time. These electrodes are then connected to the recording machine. When the machine lifts electrical pulses, the results are recorded on the rolling graphic paper. ECG can be admitted in a doctor's office, in an emergency room or even in the home using a portable heart monitor called Holter Monitor. This monitor records electrical impulses and heart rhythms on a 24 -hour basis. Stress and anxiety can cause a quick and irregular heart rate that would normally not be normallyLa present. In addition, the consumption of certain drugs such as colds and allergies can distort results because they stimulate the heart. In general, people who drink coffee and consume other foods and beverages containing caffeine may have abnormal results of electrocardiography.
cardiac drugs called beta blockers can often mask certain heart conditions. Usually beta blockers slow down and regulate heart rate. Many times, when the beta blocker is interrupted, the heart rhythm and the speed returns to the abnormal. It is important to communicate to the healthcare provider when using a beta blocker or any heart of the While undergoing the evaluation of electrocardiography. Cardiostimulators also slow down and regulate the heart, which can also show electrocardiography as abnormality.
In general, on the basis of the results of an electrocardiograph may be recommended for additional heart teehundredth. If the test shows abnormality, the echocardiogram may be designed. This test uses sound waves that are reflected from heart structures to visualize heart, valves and blood vessels. In addition, a stress test may be needed to see if the coronary blockade is present. Electrocardiograph may indicate the presence of heart ischemia that may indicate blocking.
Electrocardiography test sometimes causes false positive or false negative results. Because the test is not reliable, it is important to supplement it with a thorough physical examination and medical history. Sometimes the blood tests of the heart enzyme will be performed to exclude the presence of myocardial infarction or heart attack. When heartwood is damaged, cardiac enzymes go into the bloodstream and are revealed in this blood test. A combination of diagnostic tests is often needed to exclude heart events.
