  1. Postural blood pressure electrocardiographic changes are associated with falls in older people
    Saedon NI, Zainal-Abidin I, Chee KH, Khor HM, Tan KM, Kamaruzzaman SK, et al.
    Clin Auton Res, 2016 Feb;26(1):41-8.
    PMID: 26695401 DOI: 10.1007/s10286-015-0327-5
    To determine the magnitude of postural blood pressure change, differences in ECG between fallers and non-fallers were measured. Postural blood pressure change is associated with symptoms of dizziness, presyncope, and syncope.

  2. Fulltext Swallow syncope: a case report and review of literature
    Siew KSW, Tan MP, Hilmi IN, Loch A
    BMC Cardiovasc Disord, 2019 08 07;19(1):191.
    PMID: 31391000 DOI: 10.1186/s12872-019-1174-4
    BACKGROUND: Swallow or deglutition syncope is an unusual type of neurally-mediated syncope associated with life-threatening bradyarrhythmia and hypotension. It is a difficult condition to diagnose with commonly delayed diagnosis and management. There is lack of review articles that elucidate the basic demographics, clinical characteristics and management of this rare condition. This publication systematically reviews the 101 case reports published since 1793 on swallow syncope.

    CASE PRESENTATION: A 59-year-old man presented with the complaint of recurrent dizziness associated with meals. A 24-h ambulatory ECG recording confirmed an episode of p-wave asystole at the time of food intake. Oesophagogastroduodenoscopy with balloon inflation in the mid to lower oesophagus resulted in a 5.6 s sinus pause. The patient's symptoms resolved completely following insertion of a permanent dual chamber pacemaker.

    CONCLUSIONS: Swallow syncope is extremely rare, but still needs to be considered during diagnostic workup. It is commonly associated with gastro-intestinal disease. Permanent pacemaker implantation is the first line treatment.

  3. Fulltext Symptomatic presentation of carotid sinus hypersensitivity is associated with impaired cerebral autoregulation
    Tan MP, Chadwick TJ, Kerr SR, Parry SW
    J Am Heart Assoc, 2014 Jun;3(3):e000514.
    PMID: 24947997 DOI: 10.1161/JAHA.113.000514
    Carotid sinus hypersensitivity (CSH) is associated with syncope, unexplained falls, and drop attacks in older people but occurs asymptomatically in 35% of community-dwelling elders. We hypothesized that impaired cerebral autoregulation is associated with the conversion of asymptomatic CSH to symptomatic CSH. We therefore conducted a case-control study evaluating individuals with CSH with and without the symptoms of syncope or unexplained falls, as well as non-CSH controls, to determine whether the blood pressure and heart rate changes associated with CSH are associated with symptoms only when cerebral autoregulation is altered.
