BACKGROUND PRKAG2 syndrome diagnosis is already well-defined as Wolff-Parkinson-White syndrome (WPW), ventricular hypertrophy (VH) due to glycogen accumulation, and conduction system disease (CSD). Because of its rarity, there is a lack of literature focused on the treatment. The present study aimed to describe appropriate strategies for the treatment of affected family members with PRKAG2 syndrome with a long follow-up period. CASE REPORT We studied 60 selected individuals from 84 family members (32 males, 53...

Calcium channel blockers (CCBs) are responsible for a substantial portion of the mortality associated with cardiovascular medication overdose cases. Amlodipine, a dihydropyridine CCB, can cause prolonged hypotension in overdose. This report describes a severe amlodipine overdose case that was refractory to multiple therapeutic approaches. A 53-year-old male presented after ingesting eighty 10 mg amlodipine tablets in a suicide attempt. The patient was initially managed with calcium boluses, glucagon, multiple vasoactive agents, lipid emulsion infusions and hyperinsulinemic euglycemic therapy...

Whereas cardiac pacing has a very limited role overall in patients with vasovagal syncope (VVS), there are three reasons which support pacing efficacy in tilt-induced asystolic VVS. These are: (1) contrary to mixed and vasodepressor forms, an asystolic tilt response is specific, i.e., diagnostic, of VVS and is unlikely to occur in control patients without history of syncope and in patients with cardiac syncope; (2) contrary to mixed and vasodepressor forms, an asystolic tilt response predicts a similar asystolic event during prolonged ECG monitoring with a positive predictive value of 86%; (3) the available evidence from trials supports the efficacy of dual-chamber pacing with a low recurrence rate of syncope after pacing ranging from 6% up to 23% during 3 years of follow-up...

Central venous catheters are a commonly used medical device which may sometimes cause complications. We present first case who had an asystolic cardiac arrest during insertion of a central venous catheter, needed cardiopulmonary resuscitation (CPR), and was resuscitated successfully. A46-year lady presented to the emergency department due to mushroom poisoning. Acentral venous catheter was inserted through the internal jugular vein. However, the patient suddenly lost consciousness and asystole was seen on the monitor immediately after the insertion of the catheter...

OBJECTIVE: Continuous chest compressions are more effective during resuscitation in adults. Sustained inflation rapidly establishes functional residual capacity in fluid-filled lungs at birth. We sought to compare the hemodynamics and success in achieving return of spontaneous circulation in an asphyxial cardiac arrest lamb model with transitioning fetal circulation and fluid-filled lungs between subjects receiving continuous chest compressions during sustained inflation and those receiving conventional 3:1 compression-to-ventilation resuscitation...

Obesity is a rising epidemic worldwide driving people to search for remedy through nonconventional therapies. Hydroxycut products are popular supplements used as weight loss aids. Many reports revealed serious adverse effects related to their ingestion. We report the case of a 37-year-old healthy male patient who presented following an episode of syncope. On telemetry, he manifested recurrent sinus node arrests, including a symptomatic 24 s sinus pause. The patient admitted to taking Hydroxycut Hardcore for 10 days previously...

A strong evidence of outcomes for vasovagal syncope is not easily identified. It would seem reasonable that the proposed Mayo Clinic technology would be reserved for cases with severe recurrent or refractory syncope. However, recurrence levels are relatively low, and while some predictive methods have been proposed, recurrence is also influenced by the interaction that occurs during screening and examinations, i.e. recurrence diminishes once an initial diagnosis has been made. Finally, a key factor in being able to identify suitable patients relates to understanding the relative significance of the vasodepression and cardioinhibitory components-the therapy is best suited to patients that have a significant level of both components...

BACKGROUND: Paroxysmal atrioventricular block (P-AVB) is a well-known cause of syncope; however, its underlying mechanism is difficult to determine. This study aimed to evaluate a new ECG index, the "vagal score (VS)," to determine the mechanism of P-AVB. METHODS: We evaluated the VS in 20 patients with P-AVB (13 men, 7 women; aged 25-78 years [mean, 59.3 years]). The VS was developed by assigning 1 point each for the following: (1) no AVB or intraventricular conduction disturbance on the baseline ECG, (2) PR prolongation immediately before P-AVB, (3) sinus slowing immediately before P-AVB, (4) initiation of P-AVB by PP prolongation, (5) sinus slowing during ventricular asystole, and (6) resumption of AV conduction with PP shortening, and by assigning -1 point each for (7) the initiation of P-AVB by a premature beat, and (8) resumption of AV conduction by an escape beat...

Reversible acetylcholinesterase inhibitors are used as first-line treatment for myasthenia gravis. They improve symptoms by increasing concentration of acetylcholine at the neuromuscular junction and stimulating nicotinic receptors. Serious bradyarrhythmias can occur from muscarinic stimulation in heart, which in rare cases may progress to asystole. These patients can initially be managed with hyoscyamine, a muscarinic antagonist. Persistence of bradyarrhythmias even after hyoscyamine treatment may warrant pacemaker placement...

The eastern pygmy-possum (Cercartetus nanus) is a small marsupial that can express spontaneous short bouts of torpor, as well as multi-day bouts of deep hibernation. To examine heart rate (HR) control at various stages of torpor in a marsupial hibernator, and to see whether HR variability differs from deep placental hibernators, we used radiotelemetry to measure ECG and Tb while measuring the rate of O2 consumption and ventilation. The HR and rate of O2 consumption during euthermia was at its minimum (321±34 bpm, 0...

Cardiac telemetry, designed to monitor hospitalized patients with active cardiac conditions, is highly utilized outside the intensive care unit but is also resource-intensive and produces many nonactionable alarms. In a hospital setting in which dedicated monitor watchers are set up to be the first responders to system-generated alerts, we conducted a retrospective study of the alerts produced over a continuous 2-month period to evaluate how many were intercepted before nurse notification for being nonactionable, and how many resulted in code team activations...

OBJECTIVE: Sudden unexpected death in epilepsy (SUDEP) is a common cause of death in epilepsy and frequently occurs following generalized tonic-clonic seizures (GTCS) in sleep. Postictal generalized electroencephalography (EEG) suppression (PGES), postictal immobility, and periictal respiratory dysfunction are potential risk factors for SUDEP. We sought to determine whether there was a difference in respiratory dysfunction, PGES, and postictal immobility for GTCS occurring during wakefulness or sleep...

Unintentional intravascular administration of bupivacaine may cause local anesthetic systemic toxicity (LAST). Although many systems are affected in LAST, the cardiovascular effects can be life-threatening. Remifentanil is a selective, ultra-short-acting, µ-opioid receptor agonist opioid. This study assessed the effects of combined pretreatment with intravenous lipid emulsion (ILE) and remifentanil on the cardiotoxicity caused by bupivacaine in an experimental model of anesthetized rats. The rats were divided into three groups...
