e·lec·tro·car·di·o·gram

(ĭ-lĕk′trō-kär′dē-ə-grăm′)
A recording of the electrical activity of the heart. The electrocardiogram is used by doctors to analyze how well the heart is working and to diagnose abnormal heart rhythms. ♦ The machine used to record an electrocardiogram is called an electrocardiograph.

The wave forms were analyzed in all leads at 50 mm/sec and at 10 mm = 1 mV to determine PR, QRS, ST, and QT durations and P, net QRS complex, and T amplitudes.
An electrocardiogram showed that her initial rhythm was atypical atrial flutter with an excessively wide QRS complex of 280 milliseconds, and QRS morphology (lead aVR) was suggestive of potential flecainide toxicity (Figure 1a).
Three included criteria are: ST elevation [greater than or equal to] 1 mm in a lead with positive QRS complex (concordance) - 5 points, concordant ST depression [greater than or equal to] 1 mm in leads V1, V2, or V3-3 points, and ST elevation [greater than or equal to] 5 mm in a lead with negative (discordant) QRS complex - 2 points: [greater than or equal to] 3 points = 90% specificity of STEMI.
Thus before or after sinus beat (marked by red arrows), it would be physiologically impossible for the myocardium to be rapidly depolarised to produce a second QRS complex (marked by black arrows).
The followings were identified as useful indices for predicting and estimating the occurrence of a fatal arrhythmia: the interval between the peak and the end of T wave (Tp-Te),[2] the ratio of the Tp-Te interval to the QT interval ([Tp-Te/QT][3]), and the JT interval (JT), which is measured from the end of the QRS complex to Te.[4] The QT interval may be affected by sex and age.[5] However, little is known about the co-effect of the inhaled agent and sex on the corrected QT (QTc) and Tp-Te/QT and Tp-Te/JT ratios.
The QRS complex signifies the activation of the ventricles (the lower chambers), and the T wave denotes the heart's recovery phase.
In the case of the QRS complex, it lasts for more than 0.12 seconds and is wider than the normal QRS complex and it has deformed shape.
Atrial repolarization wave ([T.sub.a] wave) is usually not perceptible on the ECG as it has low magnitude of 100-200 microvolts and is usually concealed by the ensuing QRS complex [1].
The preoperative electrocardiogram (ECG) showed sinus rhythm with a narrow QRS complex (Figure 1(a)).
