Repetitive monomorphic ventricular tachycardia originating from the inferior tricuspid annulus

We report a case of an otherwise healthy 63-year-old male with incessant, highly symptomatic ventricular arrhythmia that displayed over 60,000 premature ventricular contractions and 499 runs of non-sustained ventricular tachycardia (VT) during 24 hours of ECG monitoring. The ventricular ectopy had a QRS morphology of the left bundle branch block (LBBB), however, with a superior axis. Structural heart disease was absent and the history was negative. Therefore the arrhythmia was considered to be atypical idiopathic repetitive monomorphic VT. Radiofrequency catheter ablation in an inferior region of the tricuspid ring at a site with good pacemap was successful. We conclude that idiopathic repetitive monomorphic VT may originate from uncommon locations and that QRS morphology (superior axis, LBBB, notching in inferior leads, transition at V4, duration ≥ 160 ms) can help diagnose inferior free wall tricuspid location

Fasciculoventricular accessory pathway : a misleading and unusual bypass tract

We present the case of a 25 year-old man referred for an electrophysiological study due to suspected pre-excitation as the cause of two recent syncopal episodes. The admission electrocardiogram (ECG) showed a borderline PR interval of 120 ms and apparently small delta waves visible in leads V2–V4. Intracardiac recordings showed a short HV interval of 18 ms that was stable despite decremental atrioventricular conduction. A fasciculoventricular accessory pathway was diagnosed. Administration of ajmaline normalized ECG and HV interval. We discuss electrocardiographical features of this rare bypass tract

O pożytkach, jakie płyną ze znajomości wiedzy filozoficznej dla nie-filozofów

About the benefits which come from the familiarity with philosophical knowledge for non-philosophers. Although philosophy as a science does not gain proper social respect, the traditional philosophical dilemmas about human existence in the world did not disappeared from the public discourse. Is it true that science can replace philosophy? Will not they become a quasi-philosophy? What is the value of philosophical knowledge for people who are not engaged in professional philosophy? I am looking for answers to these questions in this article.O pożytkach, jakie płyną ze znajomości wiedzy filozoficznej dla niefilozofów. Chociaż filozofia jako nauka nie cieszy się odpowiednim szacunkiem społecznym, to tradycyjne dylematy filozoficzne dotyczące człowieczej egzystencji w świecie wcale nie zniknęły z przestrzeni społecznego dyskursu. Czy faktycznie nauki przyrodnicze mogą zastąpić filozofię? Czy nie staną się wówczas quasi-filozofią? Jaka jest wartość wiedzy filozoficznej dla niezajmujących się filozofią zawodowo? Odpowiedzi na te pytania szukam w niniejszym artykule
