Splet16. mar. 2024 · The ST segment is the flat, isoelectric section of the ECG between the end of the S wave (the J point) and the beginning of the T wave. The ST Segment represents the interval between ventricular depolarization and repolarization. The most important cause of ST segment abnormality (elevation or depression) is myocardial ischaemia or infarction. SpletP-wave always positive in lead II (actually always positive in leads II, III and aVF). P-wave duration should be <0,12 s (all leads). P-wave amplitude should be ≤2,5 mm (all leads). PR interval must be 0,12–0,22 s (all leads). Common findings. P-wave must be positive in lead II, otherwise the rhythm cannot be sinus rhythm.

Refer to Figure 1. Abnormal R-wave progression implies that the gradual increase from V1 to V5 is absent. It may be broken, as in Figure 1. Any type of infarction may cause pathological R-wave progression.

SpletR-wave amplitude in V6 + S-wave amplitude in V1 should be <35 mm. R-wave amplitude in aVL should be ≤ 12 mm. R-wave amplitude in leads I, II and III should all be ≤ 20 mm.
