924 Possible Causes for Cardiac Electrophysiologic Study Abnormal, Electrocardiogram Change, Tachycardia during Pain Episodes

  • Wolff-Parkinson-White Syndrome

    The mechanism of the electrocardiogram changes was considered to be caused by the two drugs synergistic sodium channel blocking effects.[] A child old enough to express himself may complain of chest pain, palpitations, dizziness, lethargy and difficulty in breathing during episodes of tachycardia.[] What is Electrophysiology Study with Ablation? An electrophysiology (EP) study is a cardiac catheterization which evaluates the electrical system of the heart.[]

  • Lown-Ganong-Levine Syndrome

    In cases of underlying structural heart disease or coronary artery disease, episodes of tachycardia may induce cardiac stress and produce symptoms of chest pain or possibly[] Physical Findings are normal except during tachycardic episodes; cardiovascular examination may then reveal a rapid heart rate.[]

  • Cardiac Arrhythmia

    Holter monitoring - This test is essentially a portable electrocardiogram, which records changes in heart rhythm as a person goes about daily activities.[] Our Heart and Vascular Institute’s Cardiac Arrhythmia Program focuses on electrophysiology or EP, which is the study and treatment of abnormal heart rhythms.[] A particularly dangerous arrhythmia, polymorphic ventricular tachycardia (in which there is a continually changing morphology of the electrocardiogram complexes), is probably[]

  • Brugada Syndrome

    There are 3 different patterns of electrocardiogram (ECG) changes characterized as type I, II, and III.[] These ECG changes may be concealed and BrS may present with electrical storm characterized by recurrent ventricular tachycardia and fibrillation.[] Changes noted in the original electrocardiogram were of significant importance in reaching the diagnosis.[]

  • Left Bundle Branch Block

    We illustrate the case a patient with left bundle branch block (LBBB) and electrocardiogram (ECG) changes consistent with those described in Wellens' syndrome.[] These discrepancies may be due to the fact that we analyzed electrocardiograms obtained on admission, thus detecting changes in the ST-segment (an early manifestation of acute[] Resting electrocardiogram with normal QRS in lead V2 (A) compared with the same lead with ventricular pacing (B), and a return to normal QRS as pacing resolves (C).[]

  • Right Bundle Branch Block

    BACKGROUND: Left bundle branch block (LBBB) and right bundle branch block (RBBB) not only mask electrocardiogram (ECG) changes that reflect diseases but also indicate important[] On admission, after 3 syncopal episodes during nighttime, his electrocardiogram showed right bundle branch block (RBBB) with a J-point elevation of 0.6 mV in lead V 2 .[] Diagnosis Right bundle branch block causes a characteristic change on the ECG, so doctors can usually readily diagnose this condition simply by examining the electrocardiogram[]

  • Left Anterior Fascicular Block

    Can I rework an electrocardiogram after I have submitted my answer? Once you have submitted your answer for a specific electrocardiogram, you cannot change your answer.[] It is possible to observe slight changes in the electrocardiogram also with left posterior fascicular block.[] The main change of left hemiblocks in the electrocardiogram is a marked deviation of QRS axis.[]

  • Congenital Heart Block

    A case of polysplenia with congenital heart block, infarction of a splenic mass, and a short pancreas was reported. The infant died of severe heart failure at the age of 28 days. Deformity of the SA node was suspected to be the cause of congenital heart block but could not be demonstrated because of some[…][]

  • Preexcitation Syndrome

    […] or irregularly) Shortness of breath A physical exam done during a tachycardia episode will show a heart rate faster than 100 beats per minute.[] , shape changing complexes in a young individual.[] What is Electrophysiology Study with Ablation? An electrophysiology (EP) study is a cardiac catheterization which evaluates the electrical system of the heart.[]

  • Cardiomyopathy

    The electrocardiogram pattern significantly changed with time, and the echocardiogram showed weakness of wall motion around the left ventricular apex.[] Invasive cardiac catheterization or electrophysiological studies are now rarely necessary.[] Changes on your heart tracing (electrocardiogram, or ECG) - this is a tracing of the electrical activity of the heart. Changes on your chest X-ray.[]
