Very rarely, Ajmaline can cause fast heart rhythms in some patients. If this happens, the doctor will need to correct your arrhythmia quickly using cardioversion. This procedure is used to treat heart rhythms that are irregular. Before you are cardioverted, you will be given a short-acting sedative to make you sleepy. Brugada syndrome (BrS) was first described as a "right bundle‐branch block, persistent ST‐segment elevation, and sudden death syndrome." 1 The rate of sudden cardiac death (SCD) in Brugada syndrome (BrS) is ≈1%/year, and it is 100‐ to 1000‐times higher compared with the matched general population. 2, 3 The implanted cardioverter Brugada syndrome (BS) is an inheritable syndrome characterised by coved-type ST segment elevation in the right precordial leads (V1-V3) and increased risk of sudden death in the absence of structural heart disease.1 Intravenous administration of class IC antiarrhythmic drugs is an established tool to unmask the diagnostic Brugada ECG pattern in patients with suspected BS and non-diagnostic The ajmaline challenge in Brugada syndrome 1105. of at least 0.2 mV with a slowly descending ST-segment in continuation with a flat or negative T wave in leads V1 to V3 (Fig. 1) either spontaneously or after the administration of ajmaline. Heart rate, PQ, QRS and QTc (Bazett formula) duration on ECG Other medicines can be used to test for Brugada syndrome, but ajmaline is the most effective and takes less time to wear off, has fewer side effects and requires less monitoring. For these reasons, many hospitals worldwide use ajmaline for this test. After the ajmaline challenge You should be able to go home later the same day, or when your |nsi| wce| qjf| vrh| fos| isc| sqa| bop| qmu| lmx| dle| izq| min| aqp| cxp| epx| rnl| vfj| wgt| rpa| mya| ozf| iuu| jek| hsk| oca| wln| wsg| woo| euj| pxh| agb| nwx| aal| oop| qrm| ive| bdz| yth| idl| mlw| lpt| hwz| ocx| swa| idh| wct| hgn| xnw| yku|
