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. Webb17 jan. 2024 · The P wave is the first wave on the ECG because the action potential for the heart is generated in the sinoatrial (SA) node, located on the atria, which sends action …

Webb10 feb. 2024 · 1.5: Rhythm Interpretation. Each EKG rhythm has “rules” that differentiate one rhythm from another. Rules for each rhythm include paramters for measurements like rate, rhythm, PR interval length, and ratio of P waves to QRS complexes. Today we will focus only on lead II. Each “lead” takes a different look at the heart. WebbThe P wave represents depolarization of the atria and is followed by atrial contraction (systole). Atrial systole extends until the QRS complex, at which point, the atria relax. The …
