WebThe 'U' wave is a wave on an electrocardiogram (ECG). It comes after the T wave of ventricular repolarization and may not always be observed as a result of its small size. 'U' waves are thought to represent repolarization of the Purkinje fibers. However, the exact source of the U wave remains unclear. The most common theories for the origin are: 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.

The criteria suggestive of LVH on the ECG is if the height of the R wave in V6 + the depth of the S wave in V1. If this value is >35mm this is suggestive of LVH. WebSep 19, 2024 · The ECG can usually detect severe or urgent heart attacks, which cause elevation of the segment between the QRS and T waves. Smaller heart attacks sometime show signs, but not always.

Web11. T Wave Abnormalities Introduction. The T wave is the most labile wave in the ECG. T wave changes including low-amplitude T waves and abnormally inverted T waves may be the result of many cardiac and non-cardiac conditions. The normal T wave is usually in the same direction as the QRS except in the right precordial leads (see V2 below). WebJul 1, 2015 · There are different types of waves observed on ECG which denote depolarization and re-polarization of muscles of ventricle and atrium. They are P wave, R …

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… 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.
