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. WebJan 29, 2024 · The P wave is the first positive deflection on the ECG It represents atrial depolarisation Normal duration: < 0.12 s (< 120ms or 3 small squares) Characteristics of …

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. dutch dryers https://sachsscientific.com

WebThe P Wave: The P wave of an electrocardiogram (EKG or ECG) represents the depolarization (i.e., contraction) of the atrial muscles. The atria are the top two chambers of the heart. When these muscles contract, the atria pump blood into the bottom two chambers of the heart which are the ventricles. Answer and Explanation: 1 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 pace both the atria and the ventricles. Figure 1.2. 1: Image 1, Anatomy of an EKG Graph. An EKG is a graph of the heart’s electrical activity. The horizontal axis represents time.
