WebbCorrect option is A) An ECG consists of a set of three waves; these are namely the P wave, a QRS complex, and a T wave. Initiation of impulse by SA nodes and its travel through atria is represented by P wave which in turn signals systole of atria and initiation of contraction of atrial myocardium. This makes option A correct answer. WebbWhen the electrical impulse arrises from something other than the SA node. Abnormal sites include the atria and the AV junction.

A P wave is a period of electrical activity on an ECG that causes the atria of the heart to contract. The P wave is a summation wave, which means that it is electrical activity caused by many places signalling simultaneously, resulting in wave-like contractions. Pacemaker cells are present in a variety of locations and ...

Webb13 feb. 2024 · P wave A heartbeat starts with the generation of an electrical signal at the sinoatrial node (SA node)—the heart’s natural pacemaker—and that signal subsequently passes to the atrioventricular node (AV node). On an ECG, this is what the P wave, that first little blip, represents. Footage from Physiology & Pathology. Webb16 maj 2014 · We provide a correlation between local repolarization and T wave in a pseudo-ECG. Repolarization differences along all anatomic axes contribute to the T wave. T p T e _total represents total dispersion of repolarization. At T p, ≈25% of ventricular sites have been repolarized.
