E C G / Electrocardiogram :
An electrocardiogram is, essentially speaking, an ECG or EKG, a painless test that measures electrical activity in your heart. Doctors may get their clues from it about how well your heart works and detect related problems, such as irregular heartbeats (arrhythmias), heart attacks, issues of heart size and structure, and others.A very thin sensor is placed on your chest, arms, and legs in order to take an ECG. These sensors catch the electrical signals generated each time your heart beats. The machine records these signals and interprets them in a graph that describes the heart's activities in a series of waves.Through ECGs, doctors can check for several heart problems. They will be able to tell if anyone's shortness of breath, chest pains, or even dizziness might be symptomatic of a heart condition. It can even inform if there has ever been a previous heart attack or irregular rhythms, such as atrial fibrillation or conditions where parts of the heart have to work too hard.It can at times be utilized in the detection of heart conditions sometimes even before symptoms start. Most are performed in regular check-ups and especially those with some risk factors such as having high blood pressure, diabetes, or heart disease running in the family. The quick results will allow the doctors to make informed decisions concerning heart care.
