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.[] Forty-four percent of patients suffered 21 inappropriate shocks, which were caused by sinus tachycardia, atrial arrhythmias or lead malfunction.[] 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[]

  • Cocaine Abuse

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

  • Myocardial Infarction

    repolarization Brugada syndrome Peri-/myocarditis Pulmonary embolism Subarachnoid haemorrhage Metabolic disturbances such as hyperkalaemia Failure to recognize normal limits[] Vital signs showed sinus tachycardia and mild hypoxia with the patient sating 92% on room air. Abdominal ultrasound was performed, identifying a normal gallbladder.[] 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[]

  • Early Repolarization Syndrome

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

  • Hyperthyroidism

    ECG Examples Example 1 Sinus tachycardia Example 2 Related Topics Hypothyroidism Left ventricular hypertrophy References Slovis C, Jenkins R.[] 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[] Useful Tips Patients with unexplained sinus tachycardia or atrial fibrillation should have their TSH and T4 checked to look for evidence of thyrotoxicosis.[]

  • Pericardial Effusion

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

  • 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[] "Sinus Arrhythmia, Sinus Bradycardia, & Sinus Tachycardia." Quick Medical Diagnosis & Treatment 2018 Papadakis MA, McPhee SJ, Bernstein J.[] 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[]

  • 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].[] Normal sinus tachycardia is the most common among sinus tachycardia.[] Sinus tachycardia ECG readout of an individual with sinus tachycardia. Here the heart rate is around 150.[]

  • Brugada Syndrome

    KEYWORDS: J-waves; early repolarization; electrocardiography; sudden cardiac death; ventricular fibrillation[] Sinus tachycardia changes ECG morphology in some patients and stress testing should be considered before S-ICD implantation. 2017 Wiley Periodicals, Inc.[] 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[]

  • Paroxysmal Ventricular Tachycardia

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