Characteristics of right atrial activation during coronary sinus pacing.

abstract：INTRODUCTION:The advent of signal-averaged ECG (SAECG) systems for P wave analysis has made it important to determine if the use of different filtering techniques in these systems is diagnostically equivalent. METHODS AND RESULTS:Three different high-pass filtering techniques and two cutoff frequency values were used:...
