Low serum K + concentrations increase the binding of digitalis to myocardium. ), 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). st abnormality possible digitalis effect. Patient has a history of coronary artery and cerebral vascular disease. De Winter T waves: a pattern of up-sloping ST depression with symmetrically peaked T waves in the precordial leads is considered to be a STEMI equivalent, and is highly specific for an acute occlusion of the LAD. The bottom line, the ECG findings need to be placed in the clinical context in which it was taken, and compared to previous and subsequent. Should I be worried my gp isnt ringing me back yet? 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). I had a pre-op ecg with abnormal results citing nonspecific st abnormality and a normal sinus rhythm. associated with myocardial necrosis. Your thoughts are greatly appreciated. This depression is usually less than 1 mm, and produces a "scooped" appearance the "salvador dali mustache" st. The arrhythmia subsides spontaneously: ECG 2 Diagnosis. In other words, as long as they have done tests to make sure you have no blockages and no part of your heart is ischemic (not getting enough oxygen)then it is likely nothing to be concerned about. I do not believe that is correct. There is appropriate discordance, with the ST segment and T wave directed opposite to the main vector of the QRS complex. MedHelp is not a medical or healthcare provider and your use of this Site does not create a doctor / patient relationship. This concept is discussed further here. Editor-in-chief of the LITFL ECG Library. I recently had an EKG for family history. It means you need to discuss with your Dr who knows you. The most important cause of ST segment abnormality (elevation or depression) is myocardial ischaemia or infarction. The transition from ST segment to T-wave is smooth, and not abrupt. margin-right: 10px; Performance cookies are used to understand and analyze the key performance indexes of the website which helps in delivering a better user experience for the visitors. WebThe normal ST segment is flat and isoelectric. ER said I'm OK. ST depression localised to the inferior or high lateral leads is more likely to represent reciprocal change than subendocardial ischaemia. 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. i wouldnt worry bout ur ekg, especially if you were kinda hyped up about it before hand.

In this example, the ST segment is depressed in a downsloping manner with a gradually increasing depression and more rapid return of the depressed segment to the baseline. Thanks Bob - I am surprised I hadn't seen this earlier but obviously didn't miss anything. It is a NORMAL finding in someone on that drug. Therefore, digoxin side effects can be avoided by keeping blood levels within the therapeutic level. What does this mean? short pr.

Ask if this is the Dr. Susan Rhoads and another doctor agree. Well, I didn't think so but heard that you can have a heart attack wihout pain or any symptoms. Patient has a history of coronary artery and cerebral vascular disease. ST depression and T-wave inversion in the lateral leads V5-6. The most important cause of ST segment abnormality (elevation or depression) is. The normal T-wave is: Concordant in extremity leads; Positive in chest leads; The main abnormality of the T-wave is that it is inverted, i.e. Factors affecting the ST-T and U wave configuration include: "Secondary" ST-T Wave changes (these are normal ST-T wave changes solely due to alterations in the sequence of ventricular activation): "Primary" ST-T Wave Abnormalities (ST-T wave changes that are independent of changes in ventricular activation and that may be the result of global or segmental pathologic processes that affect ventricular repolarization): Example #1: "Early Repolarization": note high take off of the ST segment in leads V4-6; the ST elevation in V2-3 is generally seen in most normal ECG's; the ST elevation in V2-6 is concave upwards, another characteristic of this normal variant. Thus, digoxin causes false-positive ST depression detected by ambulatory monitoring. Raised Intracranial Pressure (ICP) (e.g. This is usually seen in leads with a dominant R wave (e.g. Nonspecific ST-T-wave changes are very common and may be seen in any lead of the electrocardiogram. } width: auto; AVNRT) typically causes widespread horizontal ST depression, most prominent in the left precordial leads (V4-6). WebThe Dig effect does not mean that you have a problem!! causes a pattern of ST elevation that is very similar to acute STEMI Heart Disease and Saturated Fat: Do the Dietary Guidelines Have It All Wrong? Hypomagnesemia reduces the activity of membrane Na + ,K + -ATPase and may increase kaliuresis and cause hypokalemia. WebDigitalis has effects on the ECG, including depression of the PR and sagging of the ST segments, decrease in T-wave amplitude, shortening of the QT interval, Digoxin effect refers to the presence on the ECG of: Downsloping ST depression with a characteristic reverse tick or Salvador Dali sagging appearance Flattened, inverted, or biphasic T waves Shortened QT interval Digoxin effect: Sagging ST segments resemble a reverse tick Other Digoxin effect features Additional ECG Features Digoxin effect refers to the presence on the ECG of: The morphology of the QRS complex / ST segment is variously described as either slurred, sagging or scooped and resembling either a reverse tick, hockey stick or (our personal favourite) Salvador Dalis moustache! ST abnormality, possible digitalis effect Abnormal ECG To give some perspective on the EKG output: Arrhythmia is a fast and/or irregular heartbeat. Three subjects (6%) had ST depression that was detected on the ambulatory recording only at times other than during the stress test.

It is associated with extensive myocardial damage and paradoxical movement of the left ventricular wall during systole. Fish oil, folic acid, vitamin C. Find out if these supplements are heart-healthy or overhyped. Nonspecific ST abnormality, probably digitalis effect - anyone else encountered this. All this time, they are telling me I am not a heart attack risk, and to not worry, well, geez, who wouldn't, I was absolutely petrified. localised ST elevation with reciprocal ST depression occurring They said I was a very low risk heart attack candidate, but, since that damn machine said what it did, they had to take precautions. A US doctor answered Learn more Common reading: "abnormal" because there are non-specific changes which are not specific enough to meet a true diagnosis, but not normal enough to say normal, so somewhat of a soft call or indecisive read, but very common and does not necessarily mean anything.
