Is a transthoracic interpretation of the electrical activity of the heart over time captured and externally recorded by skin electrodes.
A technique that records the electrical activity in the heart.
A device for recording the electrical activity that occurs during the heartbeat, electrocardiogram.
An apparatus for measuring and recording the electrical impulses of the muscles of the heart as it beats.
The process of recording the electrical impulses of the heart.
A testing method that records the electrical activity of the heart as a graph or series of waves on a strip of paper.
A technique for recording the electrical activity of the heart. Electrodes connected to the recording apparatus (electrocardiograph) are placed on the skin of the limbs and chest wall; the record itself is called an electrocardiogram. In conventional scalar electrocardiography 12 leads are recorded, but more may be employed in special circumstances.
A diagnostic procedure which records, or shows on a screen, the electrical activity of the heart muscle as it contracts and relaxes with the heartbeat. The recording is called an electrocardiogram (ECG, EKG). While ECGs may be taken directly from the heart during surgery, ECGs are routinely taken for diagnostic purposes as well: it involves placing perhaps a dozen electrodes (small plates which conduct electricity) on the skin at various locations (leads), and connecting (leading) the plates with the recording instrument (electrocardiograph). This provides a variety of views, which appear as “tracings” on the screen or recording paper. A large body of experience has been developed which permits the translation of the patient’s particular array of views into diagnostic information for the physician.
The creation and study of graphic records (electrocardiograms) produced by electric currents originating in the heart.
A device that records the electric activity of the heart to detect abnormal electric impulses through the muscle.
The abbreviation for electrocardiography, a technique used to record the electrical activity of the heart muscle, is “ECG.” This diagnostic tool is valuable for identifying heart disorders, as many of them result in abnormal electrical patterns. During the procedure, electrodes are attached to the patient’s chest, wrists, and ankles and connected to a recording machine. The machine then displays the heart’s electrical activity on a screen or as a trace, allowing healthcare professionals to analyze the data.
The practice of examining and capturing electrocardiograms alongside the use of electrocautery.
