Bradycardia

Slow Heart Rate


Presentation

  • A surrogate model for the daily use is present to underline the clinical needs.We have therefore developed, for the first time, a surrogate model that helps in daily practice to recognize and prevent TCR episodes.[ncbi.nlm.nih.gov]
  • Although these patients were drowsy and sleepy at presentation, tactile stimuli would arouse these patients to awaken and participate in an interview.[ncbi.nlm.nih.gov]
  • We present a 2-year-old girl with trisomy 21 who developed the rapid onset of bradycardia during anesthetic induction with sevoflurane. Previous reports are reviewed, postulated mechanisms discussed, and preventative strategies presented.[ncbi.nlm.nih.gov]
  • OBJECTIVE: In this study, we aimed to determine how bradycardia affected HRV analysis in patients who presented with chest pain to the ED.[ncbi.nlm.nih.gov]
  • CASE PRESENTATION: We report the case of a 93-year old diabetic man who presented for obnubilation. He had a slow atrial fibrillation, was not hypotensive and was not taking any beta-blocker.[ncbi.nlm.nih.gov]
Cerebral Palsy
  • RESULTS: A 6 year-old girl with hydranencephaly, quadriplegic cerebral palsy, and severe spasticiityn was a candidate for an intrathecal baclofen pump.[ncbi.nlm.nih.gov]

Workup

  • The bradycardia lasted 2 h, and further cardiac workup revealed no underlying abnormality.[ncbi.nlm.nih.gov]
Pulmonary Arterial Pressure Increased
  • arterial pressure, increased systemic vascular resistance (approximate 3000 dyn s/cm 5 ) and biphasic intrarenal venous flow pattern 3.5 hours prior to childbirth at GW 32 -3/7 Epigastralgia, tachycardia (160 bpm) and marked hypertension (201/111 mm[ncbi.nlm.nih.gov]
T Wave Inversion
  • T-wave inversion was the most frequent ECG abnormality (n 31 patients), followed by ST segment changes (nine patients with elevation and six with depression).[ncbi.nlm.nih.gov]
Myocardial Fibrosis
  • Myocardial fibrosis is the most common cause. Associations: Inferior acute myocardial infarction. Sick sinus syndrome. Mobitz type II. Second-degree block plus new bundle branch or fascicular block.[patient.info]
Left Ventricular Hypertrophy
  • Heart rate of 93 beats per minute (bpm) with left atrial diameter (LAD) of 35 mm, left ventricular hypertrophy and inferior vena cava diameter (IVCD) of 8 mm at GW 32 -0/7 decreased to 48 bpm with an expanded IVCD to 25 mm, dilated left atrium (LAD to[ncbi.nlm.nih.gov]

Treatment

  • Here we present the case of a young woman with ovarian cancer who demonstrated significant short-lived cardiotoxicity associated with cisplatin treatment. The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.[ncbi.nlm.nih.gov]
  • After inverse probability treatment weighting, covariates were balanced, and the association between relative bradycardia and survival persisted (p 0.001).[ncbi.nlm.nih.gov]
  • CONTEXT: Donepezil is a centrally-acting, reversible acetylcholinesterase inhibitor that is used in the treatment of Alzheimer disease.[ncbi.nlm.nih.gov]
  • Treatment When an arrhythmia is serious, you may need urgent treatment to restore a normal rhythm.[mountsinai.org]
  • However, the incidence of hypotension needing ephedrine treatment showed no significant difference between the 2 groups (P .7).[ncbi.nlm.nih.gov]

Prognosis

  • BACKGROUND: The prognosis of super-elderly patients (age 85 years) who undergo bradycardia pacemaker (PM) implantation remains unknown.[ncbi.nlm.nih.gov]
  • The lower the fetal heart rate, the worse the prognosis.[radiopaedia.org]
  • Bradycardia can also be produced by drugs such as digitalis or morphine and is a common abnormality in heart attack victims, for whom it often indicates a favourable prognosis.[britannica.com]
  • Prognosis Prognosis varies depending on what’s causing bradycardia. Some conditions can be reversed or managed through medication, lifestyle changes and regular monitoring. Others may require a pacemaker or implantable cardioverter defibrillator.[baptisthealth.com]
  • Outlook (Prognosis) The outcome depends on several factors: The kind of arrhythmia you have. (Some abnormal heart rhythms may be life threatening if not treated right away, or DO NOT respond well to treatment.)[mountsinai.org]

Etiology

  • Amisulpride-induced bradycardia is a rare condition of unknown etiology and mechanism. Asymptomatic bradycardia has been associated with amisulpride in only two cases.[ncbi.nlm.nih.gov]
  • BACKGROUND AND OBJECTIVES: Exaggerated emotional reactivity is supposed to be essential in the etiology of borderline personality disorder (BPD).[ncbi.nlm.nih.gov]
  • , although the numbers are small, in patients with presumed nonasphyxial arrest (ie, a presumed arrest of cardiac etiology), compression-only CPR was as effective as conventional CPR.[doi.org]

Epidemiology

  • He has since completed further training in emergency medicine, clinical toxicology, clinical epidemiology and health professional education.[lifeinthefastlane.com]
  • Epidemiology It is impossible to give meaningful figures on incidence and prevalence. In most young people bradycardia is physiological and represents athletic training.[patient.info]

Pathophysiology

  • This case report highlights the occurrence of this complication during a routine removal of a true vocal fold lesion at a tertiary medical center and discusses the potential pathophysiological mechanisms and proposed management options for this phenomenon[ncbi.nlm.nih.gov]
  • In this article, we will briefly review the clinical presentation, pathophysiology, diagnostic evaluation, and treatment of patients with bradycardia.Clinical PresentationCardiac output is the left ventricular forward stroke volume multiplied by the heart[doi.org]
  • The pathophysiology of sinus bradycardia is dependent on the underlying cause. [1] Commonly, sinus bradycardia is an incidental finding in otherwise healthy individuals, particularly in young adults, athletes or sleeping patients. [2] Other causes of[emedicine.com]

Prevention

  • Prevention Taking steps to prevent coronary artery disease may reduce your chance of developing an arrhythmia.[mountsinai.org]
  • Loss of Rgs5 provoked dramatically exaggerated bradycardia and significantly (P CONCLUSION: The results of this study indicate that, as a critical regulator of parasympathetic activation in the heart, Rgs5 prevents vagal-related bradycardia and AT through[ncbi.nlm.nih.gov]

  • […] withdrawn first, leading to the risk of severe bradycardia that is probably favored by the reverse Trendelenburg position as described in our case.Postoperative severe hemodynamic changes can occur even under stable spinal anesthesia; however, can be prevented[ncbi.nlm.nih.gov]
