Symptoms such as palpitations, fainting, dizziness and unexplained loss of consciousness are often notified by patients in clinical practice. Cardiological causes of these ailments could be various, inter alia, atriaventricular conduction disorders, supraventricular arrythmias or more life-threatening ventricular arrythmias. Diagnostics of these disorders includes a series of basic non-invasive research and more advanced specialistic methods. Presented case report shows problems of arrythmias diagnostics and imperfections of avaible methods...

BACKGROUND: In critically ill patients at risk for organ failure, the administration of intravenous fluids has equal chances of resulting in benefit or harm. While the intent of intravenous fluid is to increase cardiac output and oxygen delivery, unwelcome results in those patients who do not increase their cardiac output are tissue edema, hypoxemia, and excess mortality. Here we briefly review bedside methods to assess fluid responsiveness, focusing upon the strengths and pitfalls of echocardiography in spontaneously breathing mechanically ventilated patients as a means to guide fluid management...

Acute hypocalcaemia is a medical emergency that can have catastrophic implications like tetany, seizures, cardiac arrythmias or laryngospasm if left untreated. We are presenting a case of a 30-year-old female patient undergoing total abdominal hysterectomy with bilateral salpingoopherectomy under spinal anaesthesia. She developed unexpected bilateral carpal spasm intraoperatively which was promptly diagnosed and successfully managed with intravenous calcium administration. We conclude that the anaesthetist should be aware of the clinical presentation of acute hypocalcaemia, its causes and emergency management in the perioperative period to prevent any adverse outcomes...

INTRODUCTION: Myotonic dystrophies are inherited multisystemic diseases characterized by musculopathy, cardiac arrythmias and cognitive disorders. These patients are at increased risk for fatal post-surgical complications from pulmonary hypoventilation. We present a case with myotonic dystrophy and esophageal cancer who had a minimally invasive esophagectomy complicated with gastrobronchial fistulisation. PRESENTATION OF CASE: A 44-year-old male with myotonic dystrophy type 1 and esophageal cancer had a minimally invasive esophagectomy performed instead of open surgery in order to reduce the risk for pulmonary complications...

Direct exposure of cardiomyocytes to ethanol causes cardiac damage such as cardiac arrythmias and apoptotic cell death. Cardiomyocytes are connected to each other through intercalated disks (ID), which are composed of a gap junction (GJ), adherens junction, and desmosome. Changes in the content as well as the subcellular localization of connexin43 (Cx43), the main component of the cardiac GJ, are reportedly involved in cardiac arrythmias and subsequent damage. Recently, the hippo-YAP signaling pathway, which links cellular physical status to cell proliferation, differentiation, and apoptosis, has been implicated in cardiac homeostasis under physiological as well as pathological conditions...

REVIEW
Stéphane Manzo-Silberman
Palpitations: frequent reason for referral to a cardiologist. Arrythmia: rare, mostly benign. Premature extra-beats and sustained tachy-arrhythmias: more frequent or revealed during pregnancy. Hemodynamic changes in expectant women favor an environment conducive to arrhythmogenesis. AF and flutter: very rare unless structural heart disease or hyperthyroidism. Drugs: careful monitoring of the patient and dose adjustments. Cardioversion: only in case of severe symptoms or hemodynamically unstable.

BACKGROUND: Digoxin is the oldest known treatment for heart failure (HF) and has been demonstrated to reduce admissions for worsening heart failure in a large randomized trial recruiting patients in sinus rhythm with heart failure and ejection fraction <45%. This study forms the basis for current international guidelines recommending that digoxin should be considered in patients with symptomatic HF despite optimal doses of angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, β-blockers, and mineralocorticoid receptor antagonists in addition to device therapy, if indicated...

Central venous access devices are routinely used in oncology for delivering chemotherapy of which implantable chemoports are the most common. Spontaneous breakage and migration of the catheters is a very rare but known complication of the procedure. Patients will usually present with cardiac manifestations in form of chest pain or arrythmias. Herein we report a case of spontaneous breakage and cardiac migration in which the patient was asymptomatic. Patient was successfully managed by an interventional cardiologist...

Hypomagnesemia can lead to cardiac arrythmias. Recently, observational data have linked chronic proton pump inhibitor (PPI) exposure to hypomagnesemia. Whether PPI exposure increases the risk for arrhythmias has not been well studied. Using a large, single-center inception cohort of critically ill patients, we examined whether PPI exposure was associated with admission electrocardiogram readings of a cardiac arrhythmia in more than 8000 patients. There were 25.4% PPI users, whereas 6% were taking a histamine 2 antagonist...

Heart disease is common in both humans and chimpanzees, manifesting typically as sudden cardiac arrest or progressive heart failure. Surprisingly, although chimpanzees are our closest evolutionary relatives, the major cause of heart disease is different in the two species. Histopathology data of affected chimpanzee hearts from two primate centers, and analysis of literature indicate that sudden death in chimpanzees (and in gorillas and orangutans) is commonly associated with diffuse interstitial myocardial fibrosis of unknown cause...

An 18-year-old woman ingested 22 g of venlafaxine with suicidal attempt. At admittance two hours after ingestion she had serotonine syndrome, repeated seizures and hypotension. After eight hours malignant arrythmias culminated in cardiac arrest, which was successfully resuscitated. Progressive liver and cardiac failure lead to fatal outcome after 48 hours. It is discussed whether early lipid infusion should be given in case of ingestion of high doses of venlafaxine, before myoclonia, seizures, hypotension, rhabdomyolysis and liver failure developed, since these can only be treated symptomatically...

Due to the characteristics and environmental factors, electrocardiogram (ECG) signals are usually interfered by noises in the course of signal acquisition, so it is crucial for ECG intelligent analysis to eliminate noises in ECG signals. On the basis of wavelet transform, threshold parameters were improved and a more appropriate threshold expression was proposed. The discrete wavelet coefficients were processed using the improved threshold parameters, the accurate wavelet coefficients without noises were gained through inverse discrete wavelet transform, and then more original signal coefficients could be preserved...

Atrial fibrillation (AF) is the most common arrhythmia affecting millions of people in the Western countries and, due to the widespread impact on the population and its medical relevance, is largely investigated in both clinical and bioengineering sciences. However, some important feedback mechanisms are still not clearly established. The present study aims at understanding the global response of the cardiovascular system during paroxysmal AF through a lumped-parameter approach, which is here performed paying particular attention to the stochastic modeling of the irregular heartbeats and the reduced contractility of the heart...

Robotics technology promises an enhanced way of performing off-pump coronary artery bypass graft (CABG) surgery. In the robotic-assisted CABG surgery, surgeon performs the operation with intelligent robotic instruments controlled through teleoperation that replace conventional surgical tools. The robotic tools actively cancel the relative motion between the surgical instruments and the point-of-interest on the beating heart, in contrast to traditional off-pump CABG where the heart is passively constrained to dampen the beating motion...

Catecholaminergic polymorphic ventriculartachycardia (CPVT) is a lethal human arrhythmia provoked by exercise or emotional stress. It is mediated by abnormal calcium release from the sarcoplasmic reticulum through "leaky" ryanodine channels. Beta-adrenergic blockers are the therapy of choice for human CPVT but they fail to achieve complete arrhythmia control in some of the cases. Gene therapy is a potential treatment for genetic and other diseases associated with inadequate expression of a key protein.We established a new gene-delivery system to target CASQ2 knock-out mice suffering from CPVT2...
