The ECG shows 1 of 2 ST-segment morphologies in V1-V3. The “coved” QRS (shown) consists of a right bundle branch block morphology with a slowly downsloping ST segment (red arrow) and an inverted T wave (blue arrow). The ST segment may also take a saddleback appearance in these leads with an upright T wave.
Abnormal ECG (EKG). Definition and a comprehensive list of abnormal ECG types. ECG tracings and assessment tips are provided for all common abnormalities.
The ST segment abnormally upright or elevated above the baseline in ECG represents ST elevation. Basic Concept: the specificity of ST-T and U wave abnormalities is provided more by the clinical circumstances in which the ECG changes are found than by the particular changes themselves. Thus the term, nonspecific ST-T wave abnormalities, is frequently used when the clinical data are not available to correlate with the ECG findings. This does not mean that the ECG changes are unimportant! 2021-2-13 · An electrocardiogram (ECG) is a medical test done to record the electrical activity of the heart. It is a non-invasive procedure that can be done quickly.
This does not mean that the ECG changes are unimportant! Primary ST-T changes are caused by abnormal repolarization. This is seen in ischemia, electrolyte disorders (calcium, potassium), tachycardia, increased sympathetic tone, drug side effects etc. Secondary ST-T changes occur when abnormal depolarization causes abnormal repolarization. This is seen in bundle branch blocks (left and right bundle branch block), pre-excitation, ventricular hypertrophy, premature ventricular complexes, pacemaker stimulated beats etc. Similarly, ST segment abnormalities on the ECG can sometimes be due to a specific cause, such as ST segment elevation myocardial infarction, pericarditis or myocardial ischemia.
Over 90% of patients with HCM will have an abnormal ECG. 19–21 ECG abnormalities include T wave inversion (TWI), ST segment depression, pathological Q waves, conduction delay, left-axis deviation (LAD) and left atrial enlargement (LAE). A treadmill ECG stress test is considered abnormal when there is a horizontal or down-sloping ST-segment depression ≥ 1 mm at 60–80 ms after the J point. Exercise ECGs with up-sloping ST-segment depressions are typically reported as an ‘equivocal’ test.

ECG abnormalities in ST – segments .
ECG abnormalities in ST – segments . ST segments represent the plateau phase interval between depolarisation and repolarisation. If there is any disturbance in shape, height and duration of ST segments show abnormalities – a) ST-elevation.

The ST segment is normally at or near the baseline. Minor STT changes are not necessarily associated with cardiac ischemia[ 1 ]. Abnormal ECG finding Definition T wave inversion > 1 mm in depth in two or more leads V2-V6, II and aVF, or I and aVL (excludes III, aVR, and V1) ST segment depression ≥ 0.5 mm in depth in two or more leads Pathologic Q waves > 3 mm in depth or > 40 ms in duration in two or more leads (except III and aVR) Se hela listan på alliedacademies.org 4.
