- - The study aimed to identify the causes of recurrent syncope in patients with structural heart disease (SHD) who had negative electrophysiology studies (EPS), using head-up tilt tests (HUTT) and insertable loop recorders (ILR).
- - A total of 41 patients with SHD were assessed; 61% showed positive HUTT results indicating reflex syncope, while the remaining had negative results.
- - Follow-up revealed that most patients with positive HUTT results had evidence of reflex syncope, with no serious cardiac events or deaths reported during the monitoring period.
Background: Atrioventricular (AV) block is rare in Takotsubo cardiomyopathy (TC).
Case Report: A 66-year-old female presented with fatigue. Her electrocardiogram revealed 3:2 Mobitz Type II AV block, confirmed to be supra-Hisian by electrophysiological study.
Background: Various protocols exist for performing head-up tilt test (HUTT). Serious ventricular arrhythmias have been reported during HUTT using Isoprenaline (ISO) provocation and their incidence with sublingual Nitroglycerine provocation is unknown. This study aims to assess the efficacy, pattern of response, tolerability, and frequency of arrhythmias during head-up tilt test with sublingual Nitroglycerine (NTG) provocation compared to ISO) provocation.
