169 Possible Causes for Early Repolarization, Sinus Tachycardia

  • Idiopathic Ventricular Fibrillation

    BACKGROUND: Recently, we and others reported that early repolarization (J wave) is associated with idiopathic ventricular fibrillation.[ncbi.nlm.nih.gov] Forty-four percent of patients suffered 21 inappropriate shocks, which were caused by sinus tachycardia, atrial arrhythmias or lead malfunction.[ncbi.nlm.nih.gov] Marijuana use can lead to profound sinus tachycardia and frequent premature ventricular beats [4] and [25] and also has the potential to produce more significant cardiac arrhythmias[sanraffaele.it]

  • Cocaine Abuse

    Electrocardiogram on admission showed sinus tachycardia; left atrial enlargement, left ventricular hypertrophy and nonspecific T wave abnormalities over the anterior wall[bmcresnotes.biomedcentral.com] Arrhythmias: Sinus tachycardia is the most common arrhythmia and usually responds to control of agitation and IV fluids.[clinicaladvisor.com]

  • Myocardial Infarction

    repolarization Brugada syndrome Peri-/myocarditis Pulmonary embolism Subarachnoid haemorrhage Metabolic disturbances such as hyperkalaemia Failure to recognize normal limits[dx.doi.org] Vital signs showed sinus tachycardia and mild hypoxia with the patient sating 92% on room air. Abdominal ultrasound was performed, identifying a normal gallbladder.[web.archive.org] We describe a 41-year-old man who presented with steep down-sloping ST-segment elevation, paroxysmal ventricular tachycardia, severe sinus bradycardia, and intermittent complete[ncbi.nlm.nih.gov]

  • Early Repolarization Syndrome

    Abstract The syndrome of the early repolarization variant is described.[ncbi.nlm.nih.gov] Telemetry demonstrated sinus tachycardia with a PVC occurring on the T wave in the absence of bradycardia or long-short phenomena.[omicsonline.org] The disease can cause such consequences and complications as: Extrasystole; Sinus tachycardia or bradycardia; Atrial fibrillation; Cardiac blockade; Paroxysmal tachycardia[iliveok.com]

  • Hyperthyroidism

    ECG Examples Example 1 Sinus tachycardia Example 2 Related Topics Hypothyroidism Left ventricular hypertrophy References Slovis C, Jenkins R.[lifeinthefastlane.com] The most common are sinus tachycardia, an abnormally fast heart rate that tops 100 beats per minute, and atrial fibrillation, a disorganized rhythm in the heart's upper chambers[health.harvard.edu] Useful Tips Patients with unexplained sinus tachycardia or atrial fibrillation should have their TSH and T4 checked to look for evidence of thyrotoxicosis.[lifeinthefastlane.com]

  • Pericardial Effusion

    repolarization (ER) and early repolarization of left ventricular hypertrophy (ERLVH), according to a recent study.[pdfslide.us] tachycardia with low QRS voltage and QRS alternans It may be: transudative ( congestive heart failure, myxoedema, nephrotic syndrome ), exudative ( tuberculosis, spread from[en.wikipedia.org] tachycardia, low QRS voltage, and electrical alternans Enlarged cardiac silhouette seen on CXR with significant effusions 4.[slideshare.net]

  • Sinus Bradycardia

    […] consistent, and normal in morphology and duration PR Interval : Between 0.12-0.21 seconds in duration QRS complex : Less than 0.12 seconds in width, and consistent in morphology Early[wikidoc.org] "Sinus Arrhythmia, Sinus Bradycardia, & Sinus Tachycardia." Quick Medical Diagnosis & Treatment 2018 Papadakis MA, McPhee SJ, Bernstein J.[accessmedicine.mhmedical.com] Early repolarization in Caucasian athletes most commonly consists of upwardly concave ST-segments and tall and peaked T waves; in black athletes, there often is convex ST-segment[drsvenkatesan.com]

  • Sinus Tachycardia

    Mode of onset of ventricular fibrillation in patients with early repolarization pattern vs. Brugada syndrome. Eur Heart J. 2010 Feb. 31 (3):330-9. [Medline].[medscape.com] Normal sinus tachycardia is the most common among sinus tachycardia.[symptoma.com] Sinus tachycardia ECG readout of an individual with sinus tachycardia. Here the heart rate is around 150.[en.wikipedia.org]

  • Brugada Syndrome

    KEYWORDS: J-waves; early repolarization; electrocardiography; sudden cardiac death; ventricular fibrillation[ncbi.nlm.nih.gov] Sinus tachycardia changes ECG morphology in some patients and stress testing should be considered before S-ICD implantation. 2017 Wiley Periodicals, Inc.[ncbi.nlm.nih.gov] The ECG revealed sinus tachycardia, a QRS complex with an RSR’ pattern in lead V1, and coved ST segment elevation in lead V2: these patterns were compatible with Brugada syndrome[elsevier.es]

  • Paroxysmal Ventricular Tachycardia

    […] not produce early after depolarization, and should not exhibit reverse use-dependency.[omicsonline.org] A lower, but close to equal incidence of PVT was observed during sinus bradycardia and sinus tachycardia.[ncbi.nlm.nih.gov] When the tachycardia is regular, it is most important to determine whether it is a SINUS TACHYCARDIA or a SUPRAVENTRICULAR TACHYCARDIA.[ecgguru.com]
