320 Possible Causes for Left Atrial Enlargement, Tachycardia

  • Papillary Muscle Dysfunction

    Chest X Ray Left atrial enlargement may be present Echocardiography and Doppler Ultrasound Two dimensional electrocardiograph may show changes in thickness of papillary muscle[wikidoc.org] II block (2nd degree) or complete (3rd degree) atrioventricular (AV) block, ventricular tachycardia (VT), and ventricular fibrillation (VF).[msdmanuals.com] In acute mitral regurgitation, radiographic signs of left atrial enlargement are often absent 5.[radiopaedia.org]

  • Secondary Cardiomyopathy

    He improved clinically, and on follow-up echocardiogram 11 days later he showed recovery of cardiac function, normal left ventricular ejection fraction, mild left atrial enlargement[radcliffecardiology.com] Peripheral vasoconstriction results in hypertension, tachycardia and an increase in afterload.[bmcresnotes.biomedcentral.com] If tachycardias are not treated they can become fibrillations which can be life threatening.[childrenscardiomyopathy.org]

  • Mitral Papillary Muscle Rupture

    In acute mitral regurgitation, radiographic signs of left atrial enlargement are often absent 5.[radiopaedia.org] An 86-year-old woman with a history of hypertension presented with acute onset of chest pain and evidence of shock (hypotension and tachycardia).[circ.ahajournals.org] Cardiovascular exam was pertinent for sinus tachycardia without a murmur. Pulmonary exam was notable for bibasilar crackles.[omicsonline.org]

  • Atrial Fibrillation

    atrial enlargement and hypertension.[doi.org] The complex structure and special conductive properties of the SVC can result in complicated atrial tachycardia (AT), atrial flutter, or AF.[ncbi.nlm.nih.gov] In the emergency department, atrial fibrillation persisted and he experienced additional episodes of ventricular tachycardia.[ncbi.nlm.nih.gov]

  • Tachyarrhythmia

    atrial enlargement and hypertension.[doi.org] What difference between tachycardia & tachyarrhythmia? In brief: Arrhythmia Tachycardia is a general term applied to any fast heart rate including tachyarrhythmias.[healthtap.com] Best Answer: Tachycardia comes from the Greek words tachys (rapid or accelerated) and kardia (of the heart).[answers.yahoo.com]

  • Ventricular Septal Defect

    Furthermore, the increased pulmonary flow leads to left atrial enlargement and increased left ventricular preload and stroke volume by the Frank-Starling mechanism.[cvphysiology.com] Complications included transient ventricular tachycardia in three patients, device embolization in one patient, and tracheal bleeding in one patient.[ncbi.nlm.nih.gov] Larger VSDs may show cardiomegaly (particularly left atrial enlargement although the right and left ventricle can also be enlarged).[radiopaedia.org]

  • Premature Atrial Contractions

    For instance, as recognized by the investigators, sleep apnea or left atrial enlargement, or both, could result in heightened atrial ectopy and could also increase stroke[onlinejacc.org] […] during tachycardia was not suggestive for atrioventricular nodal reentry tachycardia.[degruyter.com] In patients with underlying predispositions (e.g. left atrial enlargement, ischaemic heart disease, WPW), a PAC may be the trigger for the onset of a re-entrant tachydysrhythmia[lifeinthefastlane.com]

  • Atrial Arrhythmia

    CONCLUSIONS: The prolonged P-wave duration recorded with P-wave signal-averaged electrocardiogram, together with advanced age and left atrial enlargement, is a potent and[ncbi.nlm.nih.gov] The mechanism of atrial tachycardia was scar related intra-atrial reentry (n 27), cavotricuspid-related atrial flutter (n 21), atrial fibrillation (n 2), or focal atrial tachycardia[ncbi.nlm.nih.gov] In CA patients, atrial fibrillation might occur in the absence of left atrial (LA) enlargement.[ncbi.nlm.nih.gov]

  • Dilated Cardiomyopathy

    Common ECG associations with DCM Left atrial enlargement - may progress to atrial fibrillation.[lifeinthefastlane.com] The treatment is of a dilated cardiomyopathy is aimed at the cause if potentially reversible (i.e. selenium deficiency or tachycardia mediated) and towards blockage of the[healio.com] Other causes include prolonged tachycardia, toxoplasmosis , thyrotoxicosis , and beriberi .[merckmanuals.com]

  • Cardiomyopathy

    Common ECG associations with DCM Left atrial enlargement - may progress to atrial fibrillation.[lifeinthefastlane.com] Case 2 presented isolated LVNC with nonsustained ventricle tachycardia. A cesarean section was performed at 36 weeks' gestation because of placenta previa.[ncbi.nlm.nih.gov] Most common mode of presentation was ventricular tachycardia (VT). Two patients had left ventricular (LV) systolic dysfunction.[ncbi.nlm.nih.gov]
