WebOn the ECG, specific voltage waves — called P, Q, R, S and T — mark each heartbeat. When blood flows through your heart, it moves from your top right heart chamber (atrium) to your bottom right heart chamber (ventricle). Blood flows because electrical signals tell your atria and ventricles to squeeze (contract) and relax.
