The difference between men and women is clear even just by looking at an electrocardiogram: females present higher resting heart rate, a shorter QRS complex length and greater corrected QT interval. The development of these differences from pubertal age onward suggests that sexual hormones play a key role, although their effect is far from being completely understood. Different incidences between sexes have been reported for many arrhythmias, both ventricular and supraventricular, and also for sudden cardiac death...

BACKGROUND: Patients with Eisenmenger syndrome have a shorter lifespan than the general population. A significant proportion develop arrhythmia and some, sudden death. OBJECTIVE: The aims of this study were to characterize the frequency, type and effects of arrhythmias in adult patients with Eisenmenger's syndrome and to identify risk factors for arrhythmias. METHODS: This retrospective study included patients aged ≥ 18 years of age with Eisenmenger's syndrome from three institutions...

Use of cardiac implantable devices and catheter ablation is steadily increasing in Western countries following the positive results of clinical trials. Despite the advances in scientific knowledge, tools development, and techniques improvement we still have some grey area in the field of electrical therapies for the heart. In particular, several reports highlighted differences both in medical behaviour and procedural outcomes between female and male candidates. Women are referred later for catheter ablation of supraventricular arrhythmias, especially atrial fibrillation, leading to suboptimal results...

Scimitar syndrome is the constellation of malformations including an abnormal venous drainage of the right lung into the inferior vena cava, associated with the right lung and systemic supply to the right lung. The anomalous vein looks like the curved, Turkish sword (scimitar), hence the name.The adult form of scimitar syndrome is rare, and it is usually an incidental diagnosis based on the characteristic finding on radiological imaging since the patients are usually asymptomatic or with minimal symptoms.Our patient presented with a rare presentation of scimitar syndrome, which is tachyarrhythmia (sinus tachycardia, with episodes of supraventricular tachycardia)...

Swallowing-induced supraventricular tachyarrhythmia is an extremely rare entity with unclear pathophysiology. A 55-year-old man presented with a 2-year history of worsening presyncopal symptoms triggered only by drinking liquids of any temperature. Results of a physical examination were unremarkable except for reproducible atrial tachycardias to 180 to 210 beats/minute documented on rhythm strips when the patient was given water to drink. He underwent radiofrequency ablation with complete resolution of symptoms...

BACKGROUND: Supraventricular ectopic complexes (SVEC) originating in the pulmonary veins are known triggers of atrial fibrillation (AF) which led to the development of pulmonary vein isolation for AF. However, the long-term prevalence of SVEC after catheter ablation (CA) as compared to antiarrhythmic medication (AAD) is unknown. Our aims were to compare the prevalence of SVEC after AAD and CA and to estimate the association between baseline SVEC burden and AF burden during 24months of follow-up...

Acute stressor states are linked to neurohormonal activation that includes the adrenergic nervous system. Elevations in circulating epinephrine and norepinephrine unmask an interdependency that exists between K(+) and Mg(2+) based on their regulation of a large number of Mg(2+)-dependent Na(+)-K(+)-ATPase pumps present in skeletal muscle. The hyperadrenergic state accounts for a sudden translocation of cations into muscle with the rapid appearance of hypokalemia and hypomagnesemia. The resultant hypokalemia and hypomagnesemia will cause a delay in myocardial repolarization and electrocardiographic QTc prolongation raising the propensity for supraventricular and ventricular arrhythmias...

Cavernous angiomas are central nervous system malformations. Most common manifestations are seizures and acute focal neurological deficits. We present a case report of a seventy-one year-old man with a two-month history of behavior changes, attention deficit and indifference followed by gait unsteadiness. Neuropsychological evaluation showed severe cognitive impairment and executive dysfunction. Head computed tomography depicted a supraventricular hydrocephaly. Magnetic resonance imaging revealed a small hemorrhage, contiguous to a mesencephalic cavernous angioma, obstructing the Sylvius aqueduct, causing secondary hydrocephalus...

PURPOSE: Clinicians must balance the risks from hypotension with the potential adverse effects of vasopressors. Experts have recommended a mean arterial pressure (MAP) target of at least 65 mmHg, and higher in older patients and in patients with chronic hypertension or atherosclerosis. We conducted a systematic review of randomized-controlled trials comparing higher vs lower blood pressure targets for vasopressor therapy administered to hypotensive critically ill patients. METHODS: We searched MEDLINE®, EMBASE™, and the Cochrane Central Register of Controlled Trials for studies of higher vs lower blood pressure targets for vasopressor therapy in critically ill hypotensive adult patients...

Early repolarization (ER) is a common electrocardiographic (ECG) finding that is associated with an increased risk of idiopathic ventricular fibrillation and sudden cardiac death. This study investigated whether the presence of ER is a predictor of ventricular and supraventricular ectopy as a marker for electrical instability. Standard 12-lead electrocardiograms of the first follow-up in the population-based Study of Health in Pomerania (SHIP-1) (n = 3,300, age 20 to 79 years) were analyzed to identify subjects with an ER pattern...

This study evaluated the safety and clinical benefit of ecromeximab (KW2871) combined with high-dose interferon-α2b (HDI) in patients with metastatic melanoma. We also carried out pharmacokinetic and immune monitoring studies of this combination. This was an open-label, phase 1/2 study of ecromeximab plus HDI in patients with measurable metastatic melanoma. Eligible patients received ecromeximab-HDI combination therapy: ecromeximab administered intravenously once every 2 weeks and HDI at a dose of 20 million units (MU)/m administered intravenously for 5 consecutive days per week for the first 4 weeks (induction phase) and then at 10 MU/m subcutaneously thrice weekly through week 14 (maintenance phase)...

A boy aged 7 years presented with his parents to the emergency department (ED). He had a known diagnosis of paroxysmal supraventricular tachycardia (SVT) and was under the care of paediatricians. He had been suffering episodes of palpitations and chest pain for over a year and had been prescribed atenolol 25 mg ON, though the side effects meant he had not taken it for a month prior to presentation. He had 2 previous confirmed episodes of SVT, one that reverted with Valsalva manoeuvres, and the other with intravenous adenosine...

Asthma is a chronic airway disease in which the pathological mechanisms are reversible airway obstruction, bronchial hyper reactivity, and constriction of the lower airways. Supraventricular tachycardia (SVT) is a common arrhythmia which originates above the bundle of His and causing heart rates exceeding 150 beats/min. SVT patients present with palpitation, chest pain, chest discomfort, dyspnea, hyperventilation, and lightheadedness, occasionally. Besides, extraordinary presentations of SVT are available in literature...

Differentiation of a wide complex arrhythmia can pose as a clinical challenge in the acute care setting. Two broad differentials exist including ventricular tachycardia versus supraventricular tachycardia with aberrancy, underlying bundle branch block or intrinsic conduction defect. To aid in distinguishing between supraventricular tachycardia and ventricular tachycardia, Brugada criteria is commonly used, albeit new algorithms have become more common. Marriott's sign, a taller peak in the first R wave when compared to R' is considered a specific criterion for distinguishing between these two entities and strongly favors the diagnosis of ventricular tachycardia...

PURPOSE: The occurence of supraventricular arrhythmias associate with an unfavourable prognosis in septic shock. Propafenone could be a feasible antiarrhythmic. MATERIALS AND METHODS: Patients collected over a period of 24months were divided into the three groups based on antiarrhythmic: Group1(amiodarone), Group2(propafenone), Group3(metoprolol). Type of arrhythmia, cardioversion rates, demographic, haemodynamic, laboratory parameters were recorded in the first 24h...

The efficacy of pulmonary vein antral isolation for patients with prolonged sinus pauses (PSP) on termination of atrial fibrillation has been reported. We studied the right atrial (RA) electrophysiologic and electroanatomic characteristics in such patients. Forty patients underwent electroanatomic mapping of the RA: 13 had PSP (group A), 13 had no PSP (group B), and 14 had paroxysmal supraventricular tachycardia (control group C). Group A had longer P-wave durations in lead II than did groups B and C (115.5 ± 15...

BACKGROUND: The PANARrhythMia and Heart Failure Registry (PANARM HF) characterized demographic, clinical and interventional therapy indication profiles of cardiac arrhythmia (CA) and heart failure (HF) patients in India. METHODS: Consulting Physicians (CP) who medically manage CA and HF patients enrolled patients with one or more of the following: syncope, pre-syncope, dyspnea, palpitation, fatigue and LV dysfunction. The CPs were trained by interventional cardiologists (IC) to identify CA/HF patients indicated for implantable device/radiofrequency ablation (RFA)...

REVIEW
Natasja M S de Groot, Ad J J C Bogers
Patients with a Fontan circulation are at a high risk of developing a variety of cardiac dysrhythmias after cardiac surgery. These dysrhythmias are most often supraventricular tachyarrhythmias (SVT), but ventricular tachyarrhythmias (VT) may also occur. Mechanisms underlying SVT are variable, including both ectopic activity and reentry. Over time, successive SVT may be caused by different mechanisms. The acute success rate of ablative therapy of atrial tachyarrhythmias is considerably high yet during long-term follow-up 'recurrences' frequently occur...
