Shownotes "Identification of the exact mechanism of syncope is difficult due to its paroxysmal nature. Some provocative tests, including electrophysiologic and tilt testing are recommended although they have limitations concerning sensitivity and specificity. Haemodynamic and electrocardiographic recordings during syncope are the gold standard. Conventional 24-hr Holter recording has limited yield due to the low frequency of syncope, event recorders have a higher yield but have limitations in terms of patient compliance. Implantable loop recorders (ILR) could potentially play an important role. Initially, ILRs only recorded the ECG when activated by the patient in case of syncope. Current generations also can store the ECG after automatically detected arrhythmias. Data is shown which demonstrates that automatical detection of asymptomatic arrhythmias predict syncopal events to be caused by the same type of arrhythmias. In contrast, presence of normal sinus rhythm during pre-syncope or in automatically detected episodes does not exclude arrhythmias as the mechanism of syncopal events."
