RATIONALE: Hemoptysis or hematemesis is a common clinical symptom in adults, but is unusually to be observed in children. Hemoptysis can occur with circulatory diseases, injuries, several types of systemic diseases, or systemic factors including factitious disorder (FD), which is difficult to be diagnosed. Here, we report a case of hemoptysis caused by FD to provide a diagnostic flow chart for such kind of disease. PATIENT CONCERNS: An 11-year-old female patient had a history of hemoptysis or hematemesis for 6 months and suffered with paroxysmal syncope for a month...

Panteleimon E Papakonstantinou, Emmanuel N Simantirakis
Although atrial fibrillation (AF) is an arrhythmia with a variable clinical profile (symptomatic and asymptomatic episodes), the first symptomatic episode leads to its initial diagnosis in most cases. Nowadays, continuous and remote long- term cardiac rhythm monitoring is feasible by the use of implantable loop recorders. The data concerning the AF recurrences and progression after the first ECG- documented clinical AF episode demonstrates that a high percentage of patients may not suffer any other AF recurrence, or may present a low recurrence rate of the arrhythmia in the future...

Background . Though several studies about prevalence, etiology, clinical characteristics, preceding events, clinical management, and outcome of Tako-Tsubo cardiomyopathy (TTC) exist, the current knowledge of TTC remains limited. Objective . In 2006, TTC was classified among the acquired forms of cardiomyopathy. On the basis of pathophysiological implications, we analyzed whether the presence of ST-segment elevation in lead -aVR (i.e., ST-segment depression in aVR) and the simultaneous absence of ST-segment elevation in lead V1 allow a reliable differentiation of TTC from acute anterior ST-segment elevation myocardial infarction (STEMI)...

Takotsubo cardiomyopathy (TC) is acute stress-induced cardiomyopathy with characteristic transient wall motion abnormalities. TC has a clinical presentation similar to an acute coronary syndrome, including chest pain or dyspnoea, ECG changes and elevated cardiac enzymes. TC often occurs after emotional stress. There are approximately 50 TC cases reported related to seizure activity, and our review revealed 15 articles which were associated with status epilepticus. This condition can be a serious complication of seizures...

BACKGROUND/RATIONALE: Atrial fibrillation (AF) is frequent and causes great morbidity in the aging population. While initial events may be symptomatic, many patients have silent AF and are at risk of ischemic embolic complications. Timely detection of asymptomatic patients is paramount. The HECTO-AF trial aims to investigate the efficacy of an electrocardiogram (ECG) handheld device for the detection of AF in patients in hospital without a prior diagnosis of AF. METHODS/DESIGN: The "Handheld ECG tracking of in-hospital atrial fibrillation" (HECTO-AF) study is a single-center, open-label, randomized controlled trial...

Several antimalarial drugs are known to prolong ventricular repolarization as evidenced by QT/QTc interval prolongation. This can lead to Torsades de Pointes, a potentially lethal ventricular arrhythmia. Whether this is the case with artemisinin-based combination therapies (ACTs) remains uncertain. Assessment of the extent of QTc prolongation with antimalarials is hampered by important variations of heart rate during malaria crises and previous studies have reported highly variable values of QTc prolongations with ACTs...

BACKGROUND Acute chest pain is a common presentation in emergency departments worldwide. Ruling out acute coronary syndrome is essential in ensuring patient safety. Workup includes electrocardiogram (ECG) and cardiac biomarkers. Wellens syndrome is characterized by a history of chest pain, normal or minimally elevated biomarkers, no STEMI/Q-waves, and specific ECG changes. These changes consist of biphasic T waves in lead V2 and V3 or deep symmetrically inverted T waves in leads V1-V4. CASE REPORT A 55-year-old male presented to the emergency department with acute chest pain in a background of active smoking, hypertension, and hyperlipidemia...

Elevation of cardiac troponins above the 99th percentile of a healthy reference population is established as a marker for myocardial cell damage and is crucial for the diagnosis of myocardial infarction. In addition, corresponding clinical evidence of acute myocardial ischemia i.e. symptoms, changes in the electrocardiogram (ECG), wall motion abnormalities or suggestive angiographic findings are required for the diagnosis of myocardial infarction. Using modern highly sensitive assays myocardial infarction can be detected more frequently and earlier...
