ECG Video lecture: The T wave: normal, inverted (negative) hyperacute and flat T waves

…left ventricle is usually considerably larger than the right ventricle, the QRS complex is actually a reflection of the electrical potentials generated by the left…

…reason why the ST segment is flat and isoelectric (i.e in level with the baseline). Displacement of the ST segment is of fundamental importance…

…of chest compressions. Identifying return of spontaneous circulation (ROSC). Prognostication. Potential reasons for a flat ETCO2 curve include: Ventilator or capnograph not activated. Displacement of…

…means that it should be flat and on the same level as the baseline (recall that the baseline is the level of the PR segment)…

…isolated implies that none of the neighboring leads display T wave inversions. aVF generally shows a positive T wave but it may occasionally be flat…
