Total Q wave duration (QWD) and amplitude (QWA) were calculated as the absolute sums of data from 12 surface leads. Results 155 patients underwent same day ECG and CMR (29±6 days post MI). QWD on ECG correlated
The initial ECGs in 440 patients admitted for suspected acute myocardial infarction were retrospectively analyzed to determine predictive values of these ECGs for acute myocardial infarction and to determine differences in the initial ECG for Q wave and non-Q wave myocardial infarction. One hundred (23...
a. What does each wave of the ECG represent? b. Explain what is occurring in the heart at each wave. What causes pulse? Why would there be a delay between the ECG pattern and the resulting beat of the heart? Which of the following is true concerning Diastole? A. In the normal 'res...
What is sinus rhythm in an ECG? What does the P wave represent on an electrocardiogram? What are S waves? What are body waves? What is a tidal wave? What do all waves have in common? What is the trough of a wave? What does the trough of a wave refer to? What are the subtypes ...
What changes are more likely to be seen on an electrocardiogram (ECG) if this patient is a suspected case of unstable angina?A. Diffuse ST-segment elevation in all the leadsB. Deep, symmetric T-wave inversions in V2 and V3 accompanied by flat ST-segmentC. An R-wave in V1 accompanied ...

Seventy-two percent of the patients with a Q wave infarction had acute injury as the initial ECG interpretation compared with 38% in the non-Q wave infarction group ( P < .001). In contrast, only 17% of patients with Q wave infarction had an initial ECG interpretation of ischemia or ...
