WebJun 3, 2024. Home ECG Library ECG Diagnosis. ECG Library Homepage. Hypokalaemia is defined as a serum potassium level of < 3.5 mmol/L. ECG changes generally do not manifest until there is a moderate degree of hypokalaemia (2.5-2.9 mmol/L). The earliest ECG manifestation of hypokalaemia is a decrease in T wave amplitude. WebSeptal q-waves are small q-waves frequently seen in the lateral leads (V5, V6, aVL, I). They are due to the normal depolarization of the ventricular septum (see previous discussion). Two small septal q-waves can actually be seen in V5–V6 in Figure 10 (left hand side).
