The ecg features of digoxin effect are seen with therapeutic doses of digoxin and Basic Concept: the specificity of ST-T and U wave abnormalities is provided more by the clinical circumstances The most common T-wave abnormality is a biphasic T wave with an initial negative deflection and terminal positive deflection. Low serum K + concentrations increase the binding of digitalis to myocardium. Weblorraine chase suffolk. The changes may be seen in all or most of the leads (diffuse changes), or they may be present contiguous leads, such as the inferior, lateral, or anterior leads. I do not believe that is correct.

It is a NORMAL finding in someone on that drug. I have St segment depression on EKGs and it is considered a normal variant since I have had a nuclear stress test that shows that I have no ischemia. Ventricular Rate: 87 Atrial Rate: 87 PR Interval: 142 QRS Duration: 78 QT/QTc: 366/440 ms P-R-T Axis: 26 : 17 : 112 degrees. May see PR segment depression, a manifestation of atrial injury, Left ventricular hypertrophy (in right precordial leads with large S-waves), Left bundle branch block (in right precordial leads with large S-waves), Hypothermia (prominent J-waves or Osborne waves), Pseudo-ST-depression (wandering baseline due to poor skin-electrode contact), Physiologic J-junctional depression with sinus tachycardia (most likely due to atrial repolarization), Hyperventilation-induced ST segment depression, Subendocardial ischemia (exercise induced or during angina attack - as illustrated below), ST segment depression is often characterized as "horizontal", "upsloping", or "downsloping", Reciprocal changes in acute Q-wave MI (e.g., ST depression in leads I & aVL with acute inferior MI), RVH (right precordial leads) or LVH (left precordial leads, I, aVL), Secondary ST segment changes with IV conduction abnormalities (e.g., RBBB, LBBB, WPW, etc). Ischemia affects the plateau phase (phase 2) and the rapid repolarization phase (phase 3), which is why ischemia causes changes to the ST segment and T-wave (ST-T changes). ), Metabolic factors (e.g., hypoglycemia, hyperventilation), Atrial repolarization (e.g., at fast heart rates the atrial T wave may pull down the beginning of the ST segment), Ventricular conduction abnormalities and rhythms originating in the ventricles, ST-T changes seen in bundle branch blocks (generally the ST-T polarity is opposite to the major or terminal deflection of the QRS), ST-T changes in PVCs, ventricular arrhythmias, and ventricular paced beats, Drug effects (e.g., digoxin, quinidine, etc), Electrolyte abnormalities (e.g., hypokalemia), Neurogenic effects (e.g., subarrachnoid hemorrhage causing long QT), Acute transmural injury - as in this acute anterior MI, Persistent ST elevation after acute MI suggests ventricular aneurysm, ST elevation may also be seen as a manifestation of Prinzmetal's (variant) angina (coronary artery spasm), ST elevation during exercise testing suggests extremely tight coronary artery stenosis or spasm (transmural ischemia), Concave upwards ST elevation in most leads except aVR, No reciprocal ST segment depression (except in aVR).
