WebJan 17, 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 … WebECG interpretation starts with assessment of the P-wave and PR interval. The P-wave is generated by depolarization (activation, contraction) of the atria. The PR interval is the interval between the start of the P-wave and the start of the QRS complex. The PR interval determines whether impulse transmission from atria to ventricles is normal. simpson engineering cary ncWebDec 7, 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. simpson encore 555 washing machine manual

WebAug 23, 2024 · P Wave In a normal ECG, there's three distinct waves. Together these waves represent one heartbeat. Looked at separately, the waves tell us what's happening in the heart at a certain... WebThe point where the wave returns to the baseline marks the end of the P Wave. A QRS complex normally follows each P Wave. A normal sinus P Wave indicates that the electrical impulse responsible for the P Wave originated in the SA node and that normal depolarization of the right and left atria has occurred. SA node is the pacemaker site.
