BACKGROUND: Complete atrioventricular block in fetuses is known to be mostly associated with autoimmune disease and can be irreversible if no steroids treatment is provided. Conventional methods used in clinical practice for diagnosing fetal arrhythmia are limited since they do not reflect the primary electrophysiological conduction processes that take place in the myocardium. The non-invasive fetal electrocardiogram has the potential to better support fetal arrhythmias diagnosis through the continuous analysis of the beat to beat variation of the fetal heart rate and morphological analysis of the PQRST complex...

BACKGROUND: Charted vital signs and laboratory results represent intermittent samples of a patient's dynamic physiologic state and have been used to calculate early warning scores to identify patients at risk of clinical deterioration. We hypothesized that the addition of cardiorespiratory dynamics measured from continuous electrocardiography (ECG) monitoring to intermittently sampled data improves the predictive validity of models trained to detect clinical deterioration prior to intensive care unit (ICU) transfer or unanticipated death...

Troponin is a specific cardiac infarction isoform (TnIc, TnTc) and its determination is used for the diagnosis of myocardial infarction even with normal Electrocardiography. The increase of cardiac troponins occurs in a variety of clinical situations without an acute coronary syndrome (ACS), cardiologists and emergency physicians are often confronted with positive troponins that are difficult to interpret. Few data exist about the occurrence, the clinical characteristics and the predictive value in case of absence of ACS...

BACKGROUND: In Bangladesh, each emergency physician faces amitriptyline overdose nearly a day. An acute cardiovascular complication, one of the worst complications is mainly responsible for the mortality in tricyclic overdose. Recently, we managed ventricular tachycardia in a young female presented with an impaired consciousness 10 h after intentionally ingesting 2500 mg amitriptyline. Here, we report it, discuss how the electrocardiography is vital to acknowledge and predict it and its' complications and also the recent update of the management of it...

The optimal method of temperature management after cardiac arrest remains unknown. Methods that are most effective are usually invasive and expensive. Noninvasive methods are not as effective and obstruct access to the patient. Temperature management via rectal cooling offers some potential advantages in survivors of cardiac arrest, namely, relatively large volumes of temperature-controlled fluids can be instilled, access to the patient is not obstructed, and fluid overload can be ameliorated by removal of a fraction of instilled fluid...

The brain is a central component of cognitive and physical human performance. Measures including functional brain activation, cerebral perfusion, cerebral oxygenation, evoked electrical responses, and resting hemodynamic and electrical activity are all related to, or can predict health status or performance decrements. However, measuring brain physiology typically requires large, stationary machines that are not suitable for mobile or self-monitoring. Moreover, when individuals are ambulatory, systemic physiological fluctuations-e...

Cardiac amyloidosis (CA) is relatively rare and frequently misdiagnosed. Other disorders presenting with increased left ventricular (LV) mass can mimic its diagnosis. This case illustrates unique findings of primary light chain (AL) amyloidosis in a patient with remarkable signs of CA. Here, we report a 49-year-old man with prior diagnosis of hypertrophy cardiomyopathy (HCM) based on an echocardiogram performed 1 year earlier that presented with 8 weeks of periorbital rash. He had numbness in the past 3 years...
