Resting ECG | HUT* | CSM* | External ECG monitoring | ILR | Total | |
SA or asystolic reflex*, n | 1 | 33 | 26 | 6 | 6 | 72 |
Atrioventricular block, n | 7 | 8 | 5 | 3 | 6 | 29 |
Slow AF, n | 0 | 0 | 1 | 1 | 1 | 3 |
SA plus VT/VF, n |
0 | 0 | 0 | 1 | 1 | 2 |
Total | 8 | 41 | 32 | 11 | 14 | 106 |
*In the cases where HUT or CSM were applied, the diagnosis was asystolic (cardioinhibitory) reflex and the absence of p-waves.
AF, atrial fibrillation;CSM, carotid-sinus massage; HUT, head-up tilt test; ILR, implantable loop recorderSA, sinus arrest;VF, ventricular fibrillation; VT, ventricular tachycardia;VVS, vasovagal syncope.
