What is an electrocardiogram (ECG)? - NCBI Bookshelf

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. WebbYou'll get a detailed solution from a subject matter expert that helps you learn core concepts.
