An ECG is a procedure with the use of an electro cariograph, this means, any disturbance in the machine can alter the results. If this happens, there may be false negatives leading to wrong diagnosis.
ELECTROCARDIOGRAPH
Common methods used to perform an ECG test include placing electrodes on the chest, arms, and legs to measure the heart's electrical activity. A non-wave ECG differs from traditional ECG readings by focusing on the overall shape and pattern of the heart's electrical signals rather than just the individual waves.
Causes for poor ECG tracing can be from the patient moving or interferences from electrical appliances in the room: cell phones, a lamp plug in etc
irregular ecg
< A myocardial infarction.
When in the hospital, the person that performs Electorcardiograms (AKA: ECGs or EKGs) are usually done by EKG/ECG Technicianas, if there are none available an RN also knows how to perform them. If you're at a doctor's office, say, a Cardiologist, a Medical Assistant or nurse will perform the EKG/ECG.
ECG stands for ElectroCardioGram
Never. An ECG is a test, not an illness or disease.
Heart disease, specifically conditions like heart attacks, arrhythmias, and heart failure, can affect an ECG by causing abnormal patterns or irregularities in the heart's electrical activity. These conditions can be detected by analyzing the ECG tracing for signs of abnormalities.
An ECG provides information about the wearer of the ECG's heartrate and rhythm of the heart. It provides information about wether it is normal or abnormal.
The portion of the ECG that corresponds to atrial depolarization is called the P wave. The P wave is the first wave on the ECG.
