a. Name the waves and what each wave on the ECG represents? b. What does the ST segment on the ECG represent? What might be occurring if there are normal number of P waves but only about 40 QRS complexes present in a minute?
Why is an ECG sometimes called an EKG? Which wave on the ECG trace marks the onset of ventricular systole and why? What is the pacemaker of respiration? What is the EKG? Explain the following waves and intervals: P-wave, P-R interval, QRS wave, S-T segment, QT interval and T wave...
An inferior wall MI — also known as IWMI, or inferior MI, or inferior ST segment elevation MI, or inferior STEMI — occurs when inferior myocardial tissue supplied by the right coronary artery, or RCA, is injured due to thrombosis of that vessel.Is...
(RBBB), left bundle branch block (LBBB), left posterior hemiblock (LPH), advanced (QRS > 105 msec) left anterior hemiblock (LAH) or left IVCD with normal axis and QRS > 115 msec – acquired during ST-segment elevation myocardial infarction (STEMI) very frequently had a poor in-...
(MI) treated with a stent presents to his cardiologist for a routine physical examination. He denies any cardiac symptoms but states that he takes his pulse on a regular basis and recently has noted it to be irregular. When seen and examined, his pulse is irregular and a 12-leadECGis ...
What does ST elevation on an ECG suggest? The ST Segment represents theinterval between ventricular depolarization and repolarization. The most important cause of ST segment abnormality (elevation or depression) is myocardial ischaemia or infarction. ...
The small size of the carotid IMT (usually less than 1 mm) necessitates computer-assisted measurement using electronic calipers; when measurements are taken from M-mode images, full-screen display is necessary. Semiautomated measurement may be performed of a selected segment (usually 1 cm in ...
What does an ECG measure? A single round of the cardiac cycle shows up in 3 main “waves” on an ECG—the P wave, the QRS complex, and the T wave. These waves reflect the activities of the heart’s electrical conduction system, which is composed of specialized muscle fibers. ...
The additional prognostic data obtained with an exercise stress test includes blood pressure, heart rate response, heart rate recovery, metabolic equivalents attained, and electrocardiographic ST segment assessment. myocardial imaging, whether it is with echocardiography or nuclear imaging, substantially ...
