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. WebT-wave: Ventricular repolarisation . Normal duration of ECG segments: PR interval: 0.12 – 0.2 secs (3-5 small squares) QRS: <0.12 secs (3 small squares) ... 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.
