What Is An Electrocardiogram?

today's topic is what is an electrocardiogram ECG an electrocardiogram is a non-invasive medical procedure that is used to measure the electrical activity of the heart over a period of time using electrodes placed on the skin tiny electrical changes on the skin that arrive from the Heart during each heartbeat are detected by the electrodes these electrodes are placed on the skin of the chest arms and legs and information about the structure and function of the heart are learned in some instances men may need to have their chest shaved to allow for optimal connection it is one of the safest and least invasive methods used by millions of cardiologists in the world to detect problems in the heart the electrocardiogram is shown in the form of electrical waves which are represented on graph paper electrocardiogram monitors or machines are used during the procedure resting 12-lead ECG this is the standard test for measuring the heart's electrical function it is performed while the patient lies flat on his or her back while a computer creates a picture on graph paper of the electrical impulses moving through the heart 12 electrodes are placed on the chest arms and legs at the same time alter monitor the halter monitor is a type of electrocardiogram used to monitor the electrical activity of the heart continuously for a period of 24 hours or longer the electrodes are taped on the skin after which you may be asked to go home and continue your daily routine except for the shower the doctor may ask you to keep tab of what you do and any symptoms noticed it is mostly recommended if the doctor suspects palpitation or inadequate blood flow to your heart muscles signal averaged electrocardiogram this is a type of electrocardiogram that is more detailed in this procedure multiple electrical activities of the heart are obtained over a period of 20 minutes in order to capture abnormal heartbeats this is to check if the patient is at high risk of getting heart arrhythmia which can cause cardiac arrest the procedure is similar to the resting ECG but with highly sophisticated equipment what is measured on the ECG rate and rhythm of heartbeats size and positions of the heart chambers presence of any damage to the heart's muscle cells presence of impaired blood flow to the heart effects of cardiac drugs the function of implanted pacemakers pattern of abnormal electric activity when is an ECG performed as a routine physical examination or evaluation as a cardiac exercise test as an evaluation of symptoms of chest pain shortness of breath fainting palpitations or dizziness what conditions can be diagnosed abnormally fast or irregular heart rhythms abnormally slow heart rhythms an enlarged heart poor blood supply to the heart an abnormal position of the heart an inflammation of the heart previous heart attack damage to the heart Cardiac Arrest during emergency room or intensive care monitoring and disturbances of the heart's conducting system thank you for watching our video please do not forget to like and share the video also please subscribe to the channel to stay updated on our latest videos
