Primary outcomes
One year atrial tachycardia episode after pacemaker implantation
Key secondary outcomes
(Before implanting a pacemaker)
Clinical data: age, gender, medical history, arrhythmia type, comorbid heart disease, past history, medications, height, weight, NYHA classification,
Blood sampling: Cre, Hb, UA, BNP, proBNP, Troponin-T
ECG: heart rate, QRS wave form, presence or absence of leg block,
Trans thoracic echocardiography:
Left atrial diameter, left atrial volume, left ventricular wall thickness, LV mass index, left ventricular end diastolic diameter, left ventricular systolic diameter, left ventricular ejection fraction, E wave, deceleration time, E / e` ratio, diastolic wall strain
(Pacemaker implantation technique)
Pacemaker type, setting, lead position (right atrial appendage, right ventricular apex, other)
(After pacemaker implantation)
Atrial hypertachycardia episode (atrial rate of 180 / min or more lasting for 6 minutes or more) at 1 month, 3 months, and 6 months after pacemaker visit.
