TīmeklisPatients were categorized: (1) no NSVT; (2) NSVT; or (3) VHR episodes of uncertain etiology. The primary endpoint was all-cause mortality within 6 months of last follow-up. Conclusion: NSVT detected on routine PPM follow-up in this patient population with a preserved ejection fraction is not associated with long-term mortality. TīmeklisPolymorphic ventricular tachycardia (PMVT) is an unusual ventricular tachyarrhythmia. Perhaps its most unique characteristic is a continuously evolving QRS morphology. …
Tīmeklis2024. gada 24. marts · Ventricular fibrillation (VF) is the most important shockable cardiac arrest rhythm. This rapid and irregular electrical activity renders the ventricles unable to contract in a synchronised manner, resulting in immediate loss of cardiac output. Unless advanced life support is rapidly instituted, this rhythm is invariably fatal. Tīmeklis2024. gada 6. sept. · Bidirectional ventricular tachycardia (BVT) is a rare ventricular dysrhythmia characterised by a beat-to-beat alternation of the frontal QRS axis. It is most commonly associated with severe …
TīmeklisThe goal is to review the literature and pathophysiology regarding DE, and present a new comprehensive treatment regimen, including a truly prophylactic approach without pulpal invasiveness. A case study of a mestizo with DE is documented. Treatment of four affected mandibular premolars exhibiting three distinct diagnostic categories will ... Tīmeklis2024. gada 2. febr. · Left ventricular noncompaction (LVNC) is a type of cardiomyopathy characterized anatomically by prominent ventricular trabeculation and deep intertrabecular recesses. The mortality associated with LVNC ranges from 5% to 47%. The etiology of LVNC is yet to be fully understood, although decades have passed …
TīmeklisMonomorphic VT may be idiopathic, but most of the patients have underlying cardiac disease. VT usually originates from the ventricular myocardium; therefore, ventricular …
TīmeklisVentricular tachycardia ( V-tach or VT) is a fast heart rate arising from the lower chambers of the heart. [3] Although a few seconds of VT may not result in permanent problems, longer periods are dangerous; and multiple episodes over a short period of time are referred to as an electrical storm.
