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. WebDiagram of the surface electrocardiogram (P, QRS, T, and U waves) and the related intracardiac electrograms (SA, His, and V). The atrial (SA) electrogram represents intra-atrial conduction. The His bundle electrogram (His) represents the recording of a His potential, and the ventricular (V) electrogram represents activation of the ventricles.

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).
