Impact of Right Ventricular Pacing Determined by Electrocardiography

Impact of Right Ventricular Pacing Determined by Electrocardiography; Prospective Randomized Trial

Typically pacemaker electrode has been attached to the right ventricular apex. This method lead to Non-physiological Ventricular contraction. It has been reported to cause by ventricular dysfunction. In conclusion, this study demonstrate that impact of right ventricular pacing determined by electrocardiography was planned.

Patients who has Atrioventricular block scheduled for artificial pacemaker Randomized select 1:1 apex beats and ventricular septal beat.

Inclusion Criteria:

• Atrioventricular block, pacemaker scheduled

Exclusion Criteria:

• History of myocardial infarction
• Valvular heart disease (grade ≥ 2 )
• History of Left ventricular dysfunction ( ejection fraction <50% or LV dimension >60 mm in the pre-procedure echocardiogram)
