WebAn ECG (electrocardiogram) is a test to check the electrical activity of the heart. ECG measures the atrial and ventricular depolarization and repolarization in the form of waves. … WebFeb 2, 2024 · There are numerous types of pacemaker, including atrial pacemakers that pace only the atria, ventricular pacemakers that pace only the ventricles, and pacemakers that …

WebSep 26, 2024 · The P wave on EKG represents the atrial depolarization and contraction that occurs during mid-late diastole. P wave = Atrial Depolarization: The ventricles begin to fill with blood as blood passively flows from the atria to the ventricles (see previous section). As a result, ventricular pressure starts to increase. WebJan 31, 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. dick\u0027s sporting goods credit card synchrony
