Amal Mattu's ECG Case of the Week – February 27, 2017

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 is seen in ischemia, electrolyte disorders (calcium, potassium), tachycardia, increased sympathetic tone, drug side effects etc. Secondary ST-T changes occur when abnormal depolarization … 2017-10-2 Abnormal ECG (EKG). Definition and a comprehensive list of abnormal ECG types. ECG tracings and assessment tips are provided for all common abnormalities.

To diagnose ST-segment elevation myocardial infarction ( STEMI) this elevation must be persistent in at least two adjacent leads. 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.

A repolarization abnormality is primary if the preceding depolarization (QRS complex) is normal and secondary if the QRS complex is abnormal. Primary ST segment abnormalities Received results on EKG but do not understand results. T wave abnornmality, consider anterior ischemia ST&T wave abnornmality, consider inferior ischemia Abnormal ECG ST-T changes are more View answer ST depressions can be something abnormal.

The nonspecific st abnormality means the st segment is not normal but it has no specific explanation from the ecg. 2019-06-15 · Any abnormality of cardiac repolarization will be seen on the ECG as abnormal ST segments or T-waves. Repolarization abnormalities can be primary or secondary in etiology. A repolarization abnormality is primary if the preceding depolarization (QRS complex) is normal and secondary if the QRS complex is abnormal. Primary ST segment abnormalities Received results on EKG but do not understand results. T wave abnornmality, consider anterior ischemia ST&T wave abnornmality, consider inferior ischemia Abnormal ECG ST-T changes are more View answer ST depressions can be something abnormal. My EKG shows ST depressions and I have been diagnosed with Prinzmetal, coronary artery spasms.

Prior work demonstrates a majority of INOCA patients have coronary microvascular (CMD).2 These results support the concept that abnormal stress ECG with normal echo or perfusion test should raise the clinician’s suspicion for CMD and not dismissed as “false-positive”.2 While CMD evidenced by impaired coronary flow reserve predicts elevated MACE,2 ischemia evidenced by traditional stress testing does not stratify risk in this population.3 The results are concordant with evidence from 2021-02-13 · It is important to understand that although an ECG can detect an abnormal heart rhythm, it may not identify the cause. For instance, an ECG may show tachycardia, which is a fast heart rate, but there are many causes of this abnormal rhythm. After an abnormal ECG, additional tests may be needed determine the cause of the abnormality.

ECG findings that may be suggestive of heart disease are regarded as abnormal findings.

After an abnormal ECG, additional tests may be needed determine the cause of the abnormality. ST segment deviation occurs in a wide range of conditions, particularly acute myocardial ischemia. Because the ST segment and the T-wave are electrophysiologically related, changes in the ST segment are frequently accompanied by T-wave changes. The term ST-T segment changes (or simply ST-T changes) is used to refer to such ECG changes. 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.

Other times, an abnormal EKG can signal a medical Most clinicians regard isolated, minor, or nonspecific ST-segment and T-wave (NS-STT) abnormalities to be incidental, often transient, and benign findings in asymptomatic patients. We sought to evaluate whether isolated NS-STT abnormalities on routine electrocardiograms (ECGs) are associated with in … There are a few electrolyte abnormalities: hypokalemia, hypercalcemia, hyperkalemia and hypocalcemia. Hypokalemia is also referred to as low potassium.
