("ECG" OR " EKG") AND "Rare Syndrome"

Takotsubo cardiomyopathy (TCM) is a rare syndrome characterized by acute and transient distinctive wall motion abnormalities accompanied by other defined objective findings. There are many variants of TCM, including the reverse (or basal) subtype. While the pathogenesis is not fully understood, both endogenous and exogenous catecholamines have been implicated. This case report describes a 30-year-old active-duty military female who developed reverse TCM immediately following local anesthetic with epinephrine administration in preparation for an elective septorhinoplasty...

Kounis syndrome (KS) is a rare syndrome characterized by the co-occurrence of acute coronary syndromes in the setting of mast cell and platelet activation in response to hypersensitivity reactions. It can be manifested as coronary vasospasms, acute myocardial infarction, or stent thrombosis triggered by drugs, vaccines, foods, coronary stents, and insect bites. It is a life-threatening condition that needs to be adequately recognized for early diagnosis and appropriate treatment. In this case report, we present a 71-year-old patient with a history of arterial hypertension and non-ST elevation myocardial infarction six months earlier that was treated percutaneously with angioplasty plus stent implantation in the circumflex artery, who subsequently presented to the emergency department due to generalized itching associated with tongue swelling, dyspnea, and chest pain after ingestion of ciprofloxacin for the treatment of a urogenital infection...

Takotsubo cardiomyopathy (TC), a rare syndrome often preceded by an emotional or physical trigger, which earned the nickname broken heart syndrome, was first diagnosed in 1990. Takotsubo cardiomyopathy can mimic an ST-elevation myocardial infarction (STEMI). Originally, TC was thought to be self-limiting and benign. However, there is a 4%-5% mortality rate, which is associated with serious complications. The majority of people diagnosed with TC are postmenopausal women, but it can affect all ages. Patients will often present to the emergency department with chest pain and dyspnea...

Leopard syndrome is a rare genetic disease complex associated with multiple anomalies. The main anomalies are summarized in the acronym LEOPARD in which each letter corresponds to mnemonic for the major features of this disorder:multiple Lentigines, ECG conduction abnormalities, Ocular hypertelorism, Pulmonic stenosis, Abnormal genitalia, Retardation of growth, and sensory neural Deafness. A Four year old male patient reported with the chief complaint of decayed anterior tooth without any relevant past medical history...

Brugada syndrome is a rare syndrome, with an estimated prevalence in Europe of 1-5/10 000 population, whose initial clinical presentation can be sudden death. Although it has a characteristic electrocardiographic pattern, this can be intermittent. The authors present the case of a 32-year-old man, with no family history of syncope or sudden death, who went to the emergency department for syncope without prodromes. The initial electrocardiogram (ECG) in sinus rhythm documented an isolated and non-specific ST-segment elevation in V2...

OBJECTIVES: A newly discovered heart syndrome mimicking acute coronary syndrome has been termed 'Tako-Tsubo cardiomyopathy' (TTC). Differentiation from acute myocardial infarction using the ECG is an important issue in clinical practice. METHODS: We retrospectively analyzed patients admitted for cardiac catheterization between September 2003 and September 2006. RESULTS: From 26,593 cardiac catheterization procedures, we identified 21 patients with suggested TTC (0...

Short QT syndrome is a newly described cardiologic entity which associates a short OT interval (QT and QTc < or = 300 ms) on the surface ECG to a high risk of syncope or sudden death due to malignant ventricular arrhythmia. This extremely rare syndrome affects mainly young adults or infants and has a wide clinical expression. It is frequently associated with atrial fibrillation. Mutations in 3 different genes KCNQ1, KCNH2, and KCNJ2, all encoding cardiac ionic potassium channels have been identified in affected patients...

Cardiovascular involvement is common in connective tissue diseases (CTD), with relevant implications in terms of morbidity and mortality. Rhythm disturbances, i.e. conduction defects and tachyarrhythmias, represent a frequent clinical manifestation of CTD-associated cardiovascular damage and a possible cause of sudden death. The underlying arrhythmogenic mechanisms are probably multiple and intriguing, even though the myocardial fibrosis frequently observed at the pathological examination seems to play a pivotal role...

Long QT syndrome (LQTS) is a clinically and genetically heterogenous syndrome characterized by a lengthening of the QT interval on the surface ECG and a propensity to severe ventricular arrhythmias such as torsades de pointes and ventricular fibrillation, leading eventually to syncope and sudden death. This rare syndrome with a mendelian inheritance occurs in subjects with otherwise normal cardiac morphological examination. The potentially severe prognosis justifies a presymptomatic diagnosis. The genetic nature of the disease has been confirmed with the identification of at least six loci and five genes...
