Performance of electrophysiologic study in an asymptomatic patient with type 2 intermittent Brugada syndrome: To do or not to do?
Authors
Abstract:
Background: Brugada syndrome (BrS) is an inherited channelopathy, which is associated with sudden cardiac death due to rapid polymorphic VT or VF. There is no definite consensus regarding the management of asymptomatic patients. Some experts advocate close follow-up; others propose the programmed stimulation for risk stratification. We aimed to evaluate the benefit of complete atrial and ventricular stimulation in patients with BrS and palpitation. Case Presentation: A 30-year-old man was admitted to our hospital because of a family history of sudden cardiac death (SCD) at age less than 45 years. He complained of self-terminated episodes of palpitation with no history of syncope. Baseline ECG showed incomplete right bundle branch block (RBBB) and saddle-back-like ST deviation in V1. Flecainide challenge test (FCT) revealed Brugada pattern. Complete EPS was done for evaluation of VT/VF inducibility and probable concomitant supraventricular arrhythmias. Programmed atrial stimulation showed inducible typical slow-fast AVNRT with AH jump 75 msec. Successful slow pathway ablation was done. There was no inducible ventricular arrhythmia. Conclusions: Patients with drug-induced BrS, positive family history of SCD and also episodes of palpitation, benefit from complete EPS. However, ICD implementation is not recommended in asymptomatic patients with drug-induced BrS and negative EPS for ventricular stimulation

full textTo do or not to do?
Contrasting an imaginary German laboratory worker who in 1939 sabotaged experiments involving the mentally retarded, and an imaginary American animal liberationist who recently vandalized a primate research facility, Singer discusses civil disobedience by animal rightists. He raises and answers criticisms as to why the German worker and the animal liberationist both were justified in their act...
full textEEG in psychiatric practice : to do or not to do ?
The first electro encephalo graphy (EEG) on a human was reported by Hans Berger in 1920. The fundamental principle of EEG is to record the electrical activity produced by the brain, using electrodes. In considering the role of EEG in psychiatry almost 25 years later, Dennis Williams (1954) observed that studies of EEG recordings had offered the clinical psychiatrist little of positive value. He...
full textVaccination of Hepatitis A; To Do or Not to Do?
This letter was written because of the high incidence of acute hepatitis A in our hospital in this period of time. In December 2016 and January 2017, eight patients with acute hepatitis A were admitted to Gastroenterology Ward of Imam Hospital. Some of them had acute liver failure and fulminant hepatitis. Fulminant hepatic failure is a rare complication of hepatitis A and it occurs in about 1% ...
