WebApr 10, 2024 · An inverted P wave on an ECG is usually a sign of ectopic atrial rhythm. The action potentials that initiate myocardiocyte depolarization may come from the AV node, from regular cardiomyocytes when certain electrolytes are out of balance, or from ectopic pacemaker cells. An inverted P wave means it is upside down. WebJul 7, 2024 · How does the P wave relate to heart function? The first wave (p wave) represents atrial depolarisation. When the valves between the atria and ventricles open, 70% of the blood in the atria falls through with the aid of gravity, but mainly due to suction caused by the ventricles as they expand.

ECG Learning Center - An introduction to clinical electrocardiography

The refractory period of cardiac muscle is distinct from that of skeletal muscle. Nerves that innervate skeletal muscle have an extremely short refractory period after being subjected to an action potential (of the order of 1 ms). This can lead to sustained or tetanic contraction. In the heart, contractions must be spaced to maintain a rhythm. Unlike in muscle, repolarization occurs at a slow rate (100 ms). This prevents the heart from undergoing sustained contractions becaus… 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.
