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...

Infection with influenza type A virus may cause serious cardiovascular complications, such as myocarditis, heart failure, acute myocardial infarction. Also infection with influenza type AH1N1 may contribute to aggravation of cardiac disorders, i.e. acute coronary syndrome, heart failure, cardiogenic shock, severe ventricular arrythmias. One of the most fatal complication of influenza is pneumonia leading to acute respiratory insufficiency requiring artifitial ventilation. Symptoms of respiratory tract infections durnig influenza epidemy should always be treated with a high index of suspicion...

BACKGROUND: Preconditioning might protect the myocardium against ischemia/ reperfusion injury by reducing infarct size and preventing arrhythmias. Dexmedetomidine (DEX) is a highly selective α2-agonist used for sedoanalgesia in daily anesthetic practice. The cardioprotective effects of DEX on infarct size and on the incidence of arrhythmias observed after regional ischemia/reperfusion injury in vivo have not been reported. OBJECTIVE: The aim of this study was to determine whether DEX exhibits a preconditioning effect and reduces infarct size and the incidence and duration of arrhythmias in a regional cardiac ischemia/reperfusion model in rats...

BACKGROUND: The relationship between seizure activity and arrhythmias is not well established. Sinus tachycardia is commonly seen post seizure. Bradyarrythmias leading to seizure activity is rarely reported in the literature thus far. CASE PRESENTATION: A 62-year-old lady presented with nocturnal seizures and was subsequently started on oral anti-convulsant with no relief of her symptoms. Further investigations led to outpatient ambulatory ECGs which showed marked sinus bradycardia prior to seizure activity and post seizure atrial fibrillation with fast ventricular rate...

Cardiac hemangiomas are extremely rare benign tumors. These tumors are usually asymptomatic but they can present symptoms such as palpitations, shortness of breath, and arrythmia. We report the case of a 73-year-old man who presented with an abnormal shadow on chest computed tomography during follow-up for lung metastatic tumor after resection of his rectal cancer. A cardiac tumor was detected, and surgical resection and right ventricular plasty were successfully performed with the patient under cardiopulmonary bypass...

It is well established that elevated blood pressure constitutes a major risk factor for coronary heart disease, arrythmias, heart failure, cerebrovascular disease, peripheral artery disease and renal failure. Blood pressure level and the duration of arterial hypertension (HTN) impact target organ damage. Many studies in adults have demonstrated the role of antihypertensive therapy in preventing cardiovascular (CV) events. The so-called hard end-points, such as death, myocardial infarction (MI) or stroke, are rarely seen in children, but intermediate target organ damage, including left ventricular hypertrophy, increased intima-media thickness and microalbuminuria, is already detectable during childhood...

Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a type of cardiac arrhythmia that occurs in people with a structurally normal heart. Stress or anxiety-induced release of endogenous catecholamines causes a dysfunction in the myocytic calcium-ion channel, leading to ventricular arrhythmias that can cause dizziness, syncope, or sudden cardiac death. Since dental procedures can be anxiety-provoking, the main purpose of this paper is to report the dental management of a young patient with dental fear and CPVT...

Ventricular arrhythmia induced by drugs (pro-arrythmia) is an uncommon event, whose occurrence is unpredictable but potentially fatal. The ability of a variety of medications to induce these arrhythmias is a significant problem facing the pharmaceutical industry. Genetic variants have been shown to play a role in adverse events and are also known to influence an individual's optimal drug dose. This review provides an overview of the current understanding of the role of genetic variants in modulating the risk of drug induced arrhythmias...

Takotsubo cardiomyopathy or "heart broken syndrome" or transient apical ballooning syndrome is an increasingly reported syndrome characterized by the fact that most patients are women aged over 65 years. The most common electrocardiographic changes are ST-segment elevation and negative T waves in precordial leads. Symptoms at onset are similar to those of acute myocardial infarction; the ventricular dysfunction is shaped like a takotsubo (a Japanese pot for fishing octopus), echocardiography and ventriculography show akinesia, hipokinesia or diskinesia (ballooning) of apical segments of left ventricle and hyperkinesia of the basal; the coronary arteries are normal angiographic; the dysfunction improves rapidly within a few weeks...

BACKGROUND AND OBJECTIVE: Despite recent advances in diagnostic procedures, syncope remains unexplained in 15 to 35% of patients. If implantable loop recorder is a validated diagnostic tool for unexplained syncope, results of this strategy are largely issued from randomized studies. We lack the results of surveys. The aim of this study was to report a single center experience with implantable loop recorders, in patients with unexplained syncope. METHODS AND RESULTS: A device (Medtronic Reveal DX or XT) was implanted in 31 patients between January 2009 and January 2012...

UNLABELLED: Acute or chronic excessive consumption of alcohol can cause cardiac arrhythmias, particularly supraventricular tachyarrhythmias. Experimental and clinical data show that chronic excessive alcohol ingestion has a destructive role on cardiac tissue, which significantly deteriorates the rhythm and contractile activity, manifested by the appearance of cardiac arrythmias and dilated cardiomyopathy. AIM: The aim of this study was to evaluate and analyze the ECG changes and disturbances of cardiac rhythm and conduction in patients after an acute or chronic excessive consumption of alcohol...

It is well-known that hypertension is a very common disease, and severe cerebrovascular accidents might occur if the blood pressure is not properly controlled. However, conditions associated with uncontrolled hypertension may be overlooked, and may become critical and eventually require a surgical intervention on an urgent basis. Coronary artery disease, acute aortic syndrome, congenital and valvular heart disease, and arrhythmias are under this topic of discussion. Of them, coronary artery disease including myocardial infarction and especially postinfarction myocardial rupture, and aortic dissection are major critical situations that physicians may encounter in clinical practice...

A 15 month old boy with a ventricular septal defect (VSD) underwent percutaneous device closure of the VSD. Five days later he collapsed; on arrival to hospital he was asystolic and received prolonged cardio-pulmonary resuscitation (CPR) with intermittent return of spontaneous circulation (ROSC). He had recurrent episodic complete heart block with no ventricular escape rhythm, associated with loss of cardiac output, unresponsive to transcutaneous pacing. He was transferred to theatre, while receiving CPR, for urgent removal of the VSD device...
