What do each of the peaks represent? Describe the electrical events occurring in the heart that are responsible for the P wave, QRS complex and T waves of the ECG. What is happening to the myocardium during (1) the PR interval and (2) the ST segment?...
a. Name the waves and what each wave on the ECG represents? b. What does the ST segment on the ECG represent? What happens to each of the intervals measured in the cardiac cycle activity (P-R interval, R-R interva...
The P waves are abnormal, and they are tall, narrow, and peaked inleads II, aVF, and V1-V2. The P-wave morphology is characteristic ofaP pulmonale, a result ofright atrial hypertrophy. This may also betermed ari...

What do the segments of the ECG represent? P-wave: Atrial contraction PR interval: Represents the time taken for excitation to spread from the sino-atrial (SA) node across the atrium and down to the ventricular muscle via the bundle of His. ...
Review how to read the three primary waves of the heart that are detected in an electrocardiogram (ECG). The flashcards in this set cover the P wave, the QRS wave, and the T wave. You will learn how to differentiate among the three waves, as well as understand what is going on in ...
Those methods follow AAMI instructions and the same protocol to report the results, but different preprocessing techniques are used. de Chazal et al. [7] used two median filters to remove baseline wander. One median filter of 200-ms width to remove QRS complexes and P-waves and other of ...
T wavesrepresent therepolarisationof theventricles. Tall T waves T waves are consideredtallif they are: > 5mmin thelimb leadsAND > 10mmin thechestleads(the same criteria as ‘small’ QRS complexes) Tall T waves can be associated with: ...
How does the ECG vary and what is occurring during these conditions: junctional rhythm, second-degree heart block, and ventricular fibrillation? ECG: The ECG variation can be represented by the reduced or increased amplitude of T-waves,...
It is very common for the P waves in Atrial Tachycardia to be: A) flat. B) hidden in the T wave. C) sawtooth. D) irregular. What is an EKG? What are the peaks of an EKG? What do each of the peaks represent? Which event causes the QRS wave on an ECG tracing? ...
