Question
Chapter 13, Problem 10RQ
Summary Introduction
Introduction:
The electrical activities of the heart are recorded using a technique called electrocardiography. An electrocardiograph in the form of waves, intervals, and segments records the electrical activity of the heart on a specific paper that runs with the same speed as the electrocardiograph machine. The graphical representation is called the electrocardiogram (ECG). The ECG involves a system of 12-leads that view different regions of the heart. The waves are P wave and T wave, the segments include the PR segment and the ST segment, and a QRS complex.
