Parasystole in a Mahaim Accessory Pathway
Automaticity has been described in Mahaim pathways, both spontaneously and during radiofrequency ablation. We describe an unusual case of automatic rhythm from a Mahaim pathway presenting as parasystole. The parasystolic beats were also found to initiate tachycardia, resulting in initial presentation with incessant tachycardia and tachycardia induced cardiomyopathy.
متن کاملParasystole in a Mahaim Accessory Pathway
Hypertrophic cardiomyopathy's (HCM) association with sudden cardiac death is well recognised. The risk of sudden cardiac death is known to increase when there is a history of unexplained syncope, abnormal blood pressure response during exercise, severe left ventricular hypertrophy or a family history of unexplained death. Implantable Cardioverter Defibrillator (ICD) implantation has been widely...
متن کاملParasystole arising in the accessory pathway.
A 31-year-old man had preexcitation syndrome (WolffParkinson-White, type A ) and recurrent supraventricular tachyarrhythmias. Figure 1A shows atrial fibrillation with rapid ventricular rates (240 to 260!min). The QRS complexes have the morphology characteristic of exclusive conduction through a left-sided accessory pathway. Figure 1B, showing sinus rhythm, was obtained a day later. The 1st, 2nd...

متن کاملRadiofrequency catheter ablation of right atriofascicular (Mahaim) accessory pathways guided by accessory pathway activation potentials.
BACKGROUND Accessory pathways (APs) exhibiting "Mahaim fiber" physiology (antegrade conduction only, long conduction time, and decremental properties) often connect the lateral right atrium to the right bundle branch (right atriofascicular pathways). Potentials from these pathways have not been recorded previously. The purpose of this study was to determine whether AP activation potentials coul...
