Webb7 dec. 2024 · A normal heartbeat on ECG will show the rate and rhythm of the contractions in the upper and lower chambers. The right and left atria or upper chambers make the first wave called a “P wave" — following a flat line when the electrical impulse goes to the bottom chambers or ventricles. Webb31 jan. 2024 · What does an ECG show? If the heart is beating steadily, it will produce the typical ECG pattern: The first peak (P wave) shows how the electrical impulse (excitation) spreads across the two atria of the heart. The atria contract (squeeze), pumping blood into the ventricles, and then immediately relax.
